I'm trying to learn javascript on my own, so I'm lacking a lot. I'm trying to change the color of multiples elements depending on the color in the css of another element.
I want the javascript to detect the <div id> with a specific color, and then change the id of another <div id2>
I tried this :
if (document.getElementById("name").css('color') == "#7a5cd4") {
document.getElementById('border').setAttribute('id', 'red');
document.getElementById('line').setAttribute('id', 'linered');
}
#name {
font-size: 35px;
color: #7a5cd4;
}
#border {
width: 25px;
height: 25px;
border: 3px solid black;
padding: 10px;
margin: 10px;
border-radius: 100%
}
#red {
width: 25px;
height: 25px;
border: 3px solid red;
padding: 10px;
margin: 10px;
border-radius: 100%
}
#line {
width: 200px;
height: 20px;
border: 1px solid black
}
#linered {
width: 200px;
height: 20px;
border: 1px solid red
}
<center>
<div id="name">name</div>
<div id="border"></div>
<div id="line"></div>
</center>
window.getComputedStyle is a function that takes an element as a parameter and returns an object containing all of the styles that are being used on that object. We can then call getPropertyValue on the result to get the value of a css property.
These functions return colours in the form rgb(r, g, b), so we will need to compare the value to rgb(122, 92, 212), instead of #7a5cd4.
HTMLElement.style, however, would not work in your case as it only gets the inline style, which is when you specify the style in your html, like <div style="color: red">.
Also, it is recommended to use classes for selecting elements, instead of ids, as you can place multiple of them on the same element.
const element = document.getElementById('name');
const styles = window.getComputedStyle(element);
if (styles.getPropertyValue('color') == 'rgb(122, 92, 212)') {
document.getElementById('border').setAttribute('id', 'red');
document.getElementById('line').setAttribute('id', 'linered');
}
In order to change the id of element you:
document.getElementById('oldid').id = 'newid'
This rest of this answer fit to inline style (element style="color: value") while #BenjaminDavies answer fit more to your original question:
In order to check/change color property you:
var divOldColor = document.getElementById('oldid').style.color; // get the color to variable
if (divOldColor == '#7a5cd4') { // do something }
Put it all together we get something like this:
if (document.getElementById('name').style.color == '#7a5cd4') {
document.getElementById('border').id = 'red';
document.getElementById('line').id = 'linered';
}
.css() is not a vanilla JS function. Use .style.cssPropertyName instead.
if (document.getElementById("name").style.color === "#7a5cd4") {
document.getElementById('border').setAttribute('id', 'red');
document.getElementById('line').setAttribute('id', 'linered');
}
My goal is to make alert the user that whichever shape they click on will correspond with an appropriate message.
My problem at the moment is that I am using an if statement that if the user clicks on something with the background color of blue, it will alert them saying they clicked on a circle. Otherwise they have clicked on a square.
The results are that clicking on the blue circle will alert that we have clicked on a square.
$("div").click(function() {
if ($(this).css("background-color") == "blue") {
alert("This is a circle!");
} else {
alert("This is a square!");
}
});
#circle {
width: 100px;
height: 100px;
border-radius: 50%;
background-color: blue;
margin: 10px;
}
.square {
width: 100px;
height: 100px;
background-color: green;
margin: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="circle"></div>
<div class="square"></div>
<div class="square"></div>
.css() returns an RGB value for background colors.
$("div").click(function() {
if ($(this).css("background-color") == "rgb(0, 0, 255)") {
alert("This is a circle!");
} else {
alert("This is a square!");
}
});
#circle {
width: 100px;
height: 100px;
border-radius: 50%;
background-color: blue;
margin: 10px;
}
.square {
width: 100px;
height: 100px;
background-color: green;
margin: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="circle"></div>
<div class="square"></div>
<div class="square"></div>
You get response back as rgb values, not the actual English word.
$("div").click(function() {
if ($(this).css("background-color") == "rgb(0, 0, 255)") {
alert("This is a circle!");
} else {
alert("This is a square!");
}
});
#circle {
width: 100px;
height: 100px;
border-radius: 50%;
background-color: blue;
margin: 10px;
}
.square {
width: 100px;
height: 100px;
background-color: green;
margin: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="circle"></div>
<div class="square"></div>
<div class="square"></div>
$("div").click(function() {
console.log($(this).css("background-color"));
if ($(this).css("background-color") == "rgb(0, 0, 255)") {
alert("This is a circle!");
} else {
alert("This is a square!");
}
});
#circle {
width: 100px;
height: 100px;
border-radius: 50%;
background-color: blue;
margin: 10px;
}
.square {
width: 100px;
height: 100px;
background-color: green;
margin: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="circle"></div>
<div class="square"></div>
<div class="square"></div>
To make it even more extensible, you could use the class name as the thing you alert:
$("div").click(function() {
alert('This is a ' + $(this).prop('class'))
}
The CSS is assigned by the class not directly, the .css("background-color") will returns the rgb() value, It's better to check the class or the id attributes in your condition instead, check the sample below :
$("div").click(function() {
if ( $(this).hasClass("square") ) {
alert("This is a square!");
} else {
alert("This is a circle!");
}
});
Hope this helps.
$("div").click(function() {
if ( $(this).hasClass("square") ) {
alert("This is a square!");
} else {
alert("This is a circle!");
}
});
#circle {
width: 100px;
height: 100px;
border-radius: 50%;
background-color: blue;
margin: 10px;
}
.square {
width: 100px;
height: 100px;
background-color: green;
margin: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="circle"></div>
<div class="square"></div>
<div class="square"></div>
# is not the same as . in CSS, nor their corresponding HTML properties. This is not a distinction that is here to make problems for you, it is one introduced intentionally with a purposeful design that you must reflect in your applications to benefit from.
# or the id attribute is only for user-defined identifiers that are unique within the document. The behavior of the document element's namespace dictionary allows one to address sub-document fragments with URIs. If you want generalities in presentation or behavior, id is not the attribute one should use in the document's markup. The level at which this anti-pattern emerges as an error is arbitrary, and your case is an example.
The class atrribute of an element is for user-defined identifiers that distinguish between elements of the same semantic meaning for the purpose of behavior or presentation. The unordered collection of class identifiers that pertain to an element is not bounded, in theory. Thus, when you are designing your application and have to distinguish between elements, there is a simple, linear process for deciding whether a user-defined identifer is necessary and/or which attributes are involved:
Is there an element or attribute other than id or class that semantically makes this distinction already? The HTML standard rigorously defines many tags and attributes, and by using them in a way that is consistent with the definitions, your application gains the benefits of all new related advances without duplication of work. If new advances break your work, you will know when this will happen in advance by keeping up with the standard.
Is there any possibility that the distinction will not be applicable in a given document or will be applicable to two or more elements? The id attribute is defined as one per document; if it is useful in the static document, it could be referenced in a URI, but it must respect that one-to-one mapping or it just is not an id. The shape of an element is thus appropriate if and only if the document relates some quality one-to-one with various shapes.
If the above 2 clauses are ruled out, the distinction belongs to the class or data attribute. If a distinction may have some representational correspondence that can be expressed in CSS, the class attribute is attractive. If, however, the distinction is more quantifiable, continuous, or abstract, it may be better expressed as a data attribute.
In your case, the distinctions are shape of element and user-clicked. Because shape of element is explicitly defined as not covered by HTML but deferred to CSS, a CSS construct is required to make that distinction. This means there are few paths in your design: style attribute, class attribute, or entirely CSS implementation. Since there is more logic involved than what CSS does and you are perhaps not wanting to define shapes in geometric terms, we can rule out style and pure CSS. The class attribute is where both shapes of element should be distinguished.
Because the HTML standard does define the DOM concept of user-clicked and you have no further complications in time, your application should make use of the onclick event directly or through jQuery or your other favorite API.
Part of the evil magic of $ is that learning it is much easier than learning the underlying parts, allowing you to succeed with incomplete understandings of the system up to a finite depth, then dumping you into the arms of stackoverflow.com when you first exceed that depth. You must read the actual standards now. Write up a working app without $ at all and the mistake will be glaring so brightly that it will be seared into your eyeballs forever. $ is for people who have written enough DOM-based code to know that there just has to be a simpler easier way. It should come as a relief when first used, not as a milder introduction to HTML app design. Once you reach this epiphany, you are ready to get back to $ and whatever else, but the DOM is not a black box or a class you can skip with footnotes.
I'm trying to make little progress indicators for a form that change depending on the page you are on. I thought the easiest way to do this would be to create the circle ID's, style them, and then just add a class list with one or two stylistic changes to show something different as a specific page was brought up.
When my function executes, the new class with the changes is being added -- the dom is proving that -- but, the style is not overtaking the original.
I've tried classList.Add, classList.toggle, className.add/Classname.toggle. Nothing seems to work.
Why might that be?
function nextPage()
{
var step2 = document.getElementById("step2");
step2.classList.toggle("newClass");
};
#step2
{
height: 27px;
width: 27px;
border: 1px solid #e5e5e5;
background: linear-gradient(#f2f2f2, #e9e9e9);
border-radius: 50%;
content: "";
margin-left: 95.5px;
float: left;
}
.newClass
{
background: linear-gradient(#f2f2f2, #8c66ff);
}
<div id="step2"></div>
<br />
<p id="next" onclick="nextPage()">Next</p>
Calculating CSS Specificity Value:
As we know, it was because simply using the class name by itself had a lower specificity value and was trumped by the other selector which targeted the unordered list with the ID value. The important words in that sentence were class and ID. CSS applies vastly different specificity weights to classes and IDs. In fact, an ID has infinitely more specificity value! That is, no amount of classes alone can outweigh an ID.
For more info https://css-tricks.com/specifics-on-css-specificity/
So, more specificity use Class aswell as IDs.
!importent, also works but it note a good practice.
Hope this will help you..
Your id step2 will always override your class newClass.
Easiest solution is just to change .newClass { ... } to #step2.newClass { ... } in your CSS to make it more specific
function nextPage()
{
var step2 = document.getElementById("step2");
step2.classList.toggle("newClass");
};
#step2
{
height: 27px;
width: 27px;
border: 1px solid #e5e5e5;
background: linear-gradient(#f2f2f2, #e9e9e9);
border-radius: 50%;
content: "";
margin-left: 95.5px;
float: left;
}
#step2.newClass
{
background: linear-gradient(#f2f2f2, #8c66ff);
}
<div id="step2"></div>
<br />
<p id="next" onclick="nextPage()">Next</p>
I have not had much success finding how to style Google's new recaptcha (v2). The eventual goal is to make it responsive, but I am having difficulty applying styling for even simple things like width.
Their API documentation does not appear to give any specifics on how to control styling at all other than the theme parameter, and simple CSS & JavaScript solutions haven't worked for me.
Basically, I need to be able to apply CSS to Google's new version of reCaptcha. Using JavaScript with it is acceptable.
Overview:
Sorry to be the answerer of bad news, but after research and debugging, it's pretty clear that there is no way to customize the styling of the new reCAPTCHA controls. The controls are wrapped in an iframe, which prevents the use of CSS to style them, and Same-Origin Policy prevents JavaScript from accessing the contents, ruling out even a hacky solution.
Why No Customize API?:
Unlike reCAPTCHA API Version 1.0, there are no customize options in API Version 2.0. If we consider how this new API works, it's no surprise why.
Excerpt from Are you a robot? Introducing “No CAPTCHA reCAPTCHA”:
While the new reCAPTCHA API may sound simple, there is a high degree of sophistication behind that modest checkbox. CAPTCHAs have long relied on the inability of robots to solve distorted text. However, our research recently showed that today’s Artificial Intelligence technology can solve even the most difficult variant of distorted text at 99.8% accuracy. Thus distorted text, on its own, is no longer a dependable test.
To counter this, last year we developed an Advanced Risk Analysis backend for reCAPTCHA that actively considers a user’s entire engagement with the CAPTCHA—before, during, and after—to determine whether that user is a human. This enables us to rely less on typing distorted text and, in turn, offer a better experience for users. We talked about this in our Valentine’s Day post earlier this year.
If you were able to directly manipulate the styling of the control elements, you could easily interfere with the user-profiling logic that makes the new reCAPTCHA possible.
What About a Custom Theme?:
Now the new API does offer a theme option, by which you can choose a preset theme such as light and dark. However there is not presently a way to create a custom theme. If we inspect the iframe, we will find the theme name is passed in the query string of the src attribute. This URL looks something like the following.
https://www.google.com/recaptcha/api2/anchor?...&theme=dark&...
This parameter determines what CSS class name is used on the wrapper element in the iframe and determines the preset theme to use.
Digging through the minified source, I found that there are actually 4 valid theme values, which is more than the 2 listed in the documentation, but default and standard are the same as light.
We can see the code that selects the class name from this object here.
There is no code for a custom theme, and if any other theme value is specified, it will use the standard theme.
In Conclusion:
At present, there is no way to fully style the new reCAPTCHA elements, only the wrapper elements around the iframe can be stylized. This was almost-certainly done intentionally, to prevent users from breaking the user profiling logic that makes the new captcha-free checkbox possible. It is possible that Google could implement a limited custom theme API, perhaps allowing you to choose custom colors for existing elements, but I would not expect Google to implement full CSS styling.
As guys mentioned above, there is no way ATM. but still if anyone interested, then by adding in just two lines you can at least make it look reasonable, if it break on any screen. you can assign different value in #media query.
<div id="recaptchaContainer" style="transform:scale(0.8);transform-origin:0 0"></div>
Hope this helps anyone :-).
I use below trick to make it responsive and remove borders. this tricks maybe hide recaptcha message/error.
This style is for rtl lang but you can change it easy.
.g-recaptcha {
position: relative;
width: 100%;
background: #f9f9f9;
overflow: hidden;
}
.g-recaptcha > * {
float: right;
right: 0;
margin: -2px -2px -10px;/*remove borders*/
}
.g-recaptcha::after{
display: block;
content: "";
position: absolute;
left:0;
right:150px;
top: 0;
bottom:0;
background-color: #f9f9f9;
clear: both;
}
<div class="g-recaptcha" data-sitekey="Your Api Key"></div>
<script src='https://www.google.com/recaptcha/api.js?hl=fa'></script>
Unfortunately we cant style reCaptcha v2, but it is possible to make it look better, here is the code:
Click here to preview
.g-recaptcha-outer{
text-align: center;
border-radius: 2px;
background: #f9f9f9;
border-style: solid;
border-color: #37474f;
border-width: 1px;
border-bottom-width: 2px;
}
.g-recaptcha-inner{
width: 154px;
height: 82px;
overflow: hidden;
margin: 0 auto;
}
.g-recaptcha{
position:relative;
left: -2px;
top: -1px;
}
<div class="g-recaptcha-outer">
<div class="g-recaptcha-inner">
<div class="g-recaptcha" data-size="compact" data-sitekey="YOUR KEY"></div>
</div>
</div>
Add a data-size property to the google recaptcha element and make it equal to "compact" in case of mobile.
Refer: google recaptcha docs
What you can do is to hide the ReCaptcha Control behind a div. Then make your styling on this div. And set the css "pointer-events: none" on it, so you can click through the div (Click through a DIV to underlying elements).
The checkbox should be in a place where the user is clicking.
You can recreate recaptcha , wrap it in a container and only let the checkbox visible. My main problem was that I couldn't take the full width so now it expands to the container width. The only problem is the expiration you can see a flick but as soon it happens I reset it.
See this demo http://codepen.io/alejandrolechuga/pen/YpmOJX

Great!
Now here is styling available for reCaptcha..
I just use inline styling like:
<div class="g-recaptcha" data-sitekey="XXXXXXXXXXXXXXX" style="transform: scale(1.08); margin-left: 14px;"></div>
whatever you wanna to do small customize in inline styling...
Hope it will help you!!
I came across this answer trying to style the ReCaptcha v2 for a site that has a light and a dark mode. Played around some more and discovered that besides transform, filter is also applied to iframe elements so ended up using the default/light ReCaptcha and doing this when the user is in dark mode:
.g-recaptcha {
filter: invert(1) hue-rotate(180deg);
}
The hue-rotate(180deg) makes it so that the logo is still blue and the check-mark is still green when the user clicks it, while keeping white invert()'ed to black and vice versa.
Didn't see this in any answer or comment so decided to share even if this is an old thread.
Just adding a hack-ish solution to make it responsive.
Wrap the recaptcha in an extra div:
<div class="recaptcha-wrap">
<div id="g-recaptcha"></div>
</div>
Add styles. This assumes the dark theme.
// Recaptcha
.recaptcha-wrap {
position: relative;
height: 76px;
padding:1px 0 0 1px;
background:#222;
> div {
position: absolute;
bottom: 2px;
right:2px;
font-size:10px;
color:#ccc;
}
}
// Hides top border
.recaptcha-wrap:after {
content:'';
display: block;
background-color: #222;
height: 2px;
width: 100%;
top: -1px;
left: 0px;
position: absolute;
}
// Hides left border
.recaptcha-wrap:before {
content:'';
display: block;
background-color: #222;
height: 100%;
width: 2px;
top: 0;
left: -1px;
position: absolute;
z-index: 1;
}
// Makes it responsive & hides cut-off elements
#g-recaptcha {
overflow: hidden;
height: 76px;
border-right: 60px solid #222222;
border-top: 1px solid #222222;
border-bottom: 1px solid #222;
position: relative;
box-sizing: border-box;
max-width: 294px;
}
This yields the following:
It will now resize horizontally, and doesn't have a border. The recaptcha logo would get cut off on the right, so I am hiding it with a border-right. It's also hiding the privacy and terms links, so you may want to add those back in.
I attempted to set a height on the wrapper element, and then vertically center the recaptcha to reduce the height. Unfortunately, any combo of overflow:hidden and a smaller height seems to kill the iframe.
in the V2.0 it's not possible. The iframe blocks all styling out of this. It's difficult to add a custom theme instead of the dark or light one.
Late to the party, but maybe my solution will help somebody.
I haven't found any solution that works on a responsive website when the viewport changes or the layout is fluid.
So I've created a jQuery script for django-cms that is dynamically adapting to a changing viewport.
I'm going to update this response as soon as I have the need for a modern variant of it that is more modular and has no jQuery dependency.

With the integration of the invisible reCAPTCHA you can do the following:
To enable the Invisible reCAPTCHA, rather than put the parameters in a div, you can add them directly to an html button.
a. data-callback=””. This works just like the checkbox captcha, but is required for invisible.
b. data-badge: This allows you to reposition the reCAPTCHA badge (i.e. logo and
‘protected by reCAPTCHA’ text) . Valid options as ‘bottomright’ (the default),
‘bottomleft’ or ‘inline’ which will put the badge directly above the button. If you
make the badge inline, you can control the CSS of the badge directly.
In case someone struggling with the recaptcha of contact form 7 (wordpress) here is a solution working for me
.wpcf7-recaptcha{
clear: both;
float: left;
}
.wpcf7-recaptcha{
margin-right: 6px;
width: 206px;
height: 65px;
overflow: hidden;
border-right: 1px solid #D3D3D3;
}
.wpcf7-recaptcha iframe{
padding-bottom: 15px;
border-bottom: 1px solid #D3D3D3;
background: #F9F9F9;
border-left: 1px solid #d3d3d3;
}
if you use scss, that worked for me:
.recaptcha > div{
transform: scale(0.84);
transform-origin: 0;
}
If someone is still interested, there is a simple javascript library (no jQuery dependency), named custom recaptcha. It lets you customize the button with css and implement some js events (ready/checked). The idea is to make the default recaptcha "invisible" and put a button over it. Just change the id of the recaptcha and that's it.

I am just adding this kind of solution / quick fix so it won't get lost in case of a broken link.
Link to this solution "Want to add link How to resize the Google noCAPTCHA reCAPTCHA | The Geek Goddess" was provided by Vikram Singh Saini and simply outlines that you could use inline CSS to enforce framing of the iframe.
// Scale the frame using inline CSS
<div class="g-recaptcha" data-theme="light"
data-sitekey="XXXXXXXXXXXXX"
style="transform:scale(0.77);
-webkit-transform:scale(0.77);
transform-origin:0 0;
-webkit-transform-origin:0 0;
">
</div>
// Scale the images using a stylesheet
<style>
#rc-imageselect, .g-recaptcha {
transform:scale(0.77);
-webkit-transform:scale(0.77);
transform-origin:0 0;
-webkit-transform-origin:0 0;
}
</style>
You can use some CSS for Google reCAPTCHA v2 styling on your website:
– Change background, color of Google reCAPTCHA v2 widget:
.rc-anchor-light {
background: #fff!important;
color: #fff!important; }
or
.rc-anchor-normal{
background: #000 !important;
color: #000 !important; }
– Resize the Google reCAPTCHA v2 widget by using this snippet:
.rc-anchor-light {
transform:scale(0.9);
-webkit-transform:scale(0.9); }
– Responsive your Google reCAPTCHA v2:
#media only screen and (min-width: 768px) {
.rc-anchor-light {
transform:scale(0.85);
-webkit-transform:scale(0.85); }
}
All elements, property of CSS above that’s just for your reference. You can change them by yourself (only using CSS class selector).
Refer on OIW Blog - How To Edit CSS of Google reCAPTCHA (Re-style, Change Position, Resize reCAPTCHA Badge)
You can also find out Google reCAPTCHA v3's styling there.
A bit late but I tried this and it worked to make the Recaptcha responsive on screens smaller than 460px width. You can't use css selector to select elements inside the iframe. So, better use the outermost parent element which is the class g-recaptcha to basically zoom-out i.e transform the size of the entire container. Here's my code which worked:
#media(max-width:459.99px) {
.modal .g-recaptcha {
transform:scale(0.75);
-webkit-transform:scale(0.75); }
}
}
Incase someone wants to resize recaptcha for small devices.
I was using recaptcha V2 with primeng p-captcha (for angular). The issue was that for smaller screens it would go out of the screen.
Although you can't actually resize it (the external thing and all everyone has explained it above) but there is a way with transform property (scaling the the container)
this was my code below the way, I achieved it
p-captcha div div {
transform:scale(0.9) !important;
-webkit-transform:scale(0.9) !important;
transform-origin:0 0 !important;
-webkit-transform-origin:0 0 !important;
}
Other than p-captcha you can use this code snippet below
.g-recaptcha {
transform:scale(0.9);
transform-origin:0 0;
}

Topic is old, but I also wanted to scale the reCAPTCHA widget -- but to make it bigger for phone users, unlike many others who wanted it smaller. The only way that worked was transform: scale(x), but that seemed to make the widget too wide for my page, thus shrinking the rest of the form on the page. Using a container div as shown below fixed my problem, and hopefully it will help someone else who thinks a bigger version is better on a small screen.
<style>
:root {
/* factor to scale the Google widget in potrait mode (on a phone) */
--recaptcha-scale: 2;
}
#media screen and (orientation: portrait) {
/* needed to rein in the width of inner div when it is scaled */
#g_recaptcha_div_container {
width: calc(100vmin / var(--recaptcha-scale));
}
#g_recaptcha_div {
transform: scale(var(--recaptcha-scale));
transform-origin: 0 0;
}
#submit_button {
width: 65vmin;
height: 9vmin;
font-size: 7vmin;
/* needed to scoot the button out from under the scaled div */
margin-top: 10vmin;
}
}
</style>
<html>
<!-- top of form with a bunch of fields to create an acct -->
<div id="g_recaptcha_div_container">
<div id="g_recaptcha_div" class="g-recaptcha" data-sitekey="foo">
</div>
</div>
<input id="submit_button" type="submit" value="Create Account">
<!-- bottom of form -->
</html>
You can try to color it with this css filter hack:
.colorize-pink {
filter: brightness(0.5) sepia(1) hue-rotate(-70deg) saturate(5);
}
.colorize-navy {
filter: brightness(0.2) sepia(1) hue-rotate(180deg) saturate(5);
}
and for the size, use transform css hack
.captcha-size {
transform:scale(0.8);transform-origin:0 0
}
Lets play a little with JavaScript:
First at all, we know that recaptcha badget include all the shit from the most crazy people on Google, so you can only make changes with theme "dark" and "light" on your web.
Take a look to my website
SantiagoSoñora.
let recaptcha = document.querySelector('.g-recaptcha');
With this, you only can touch simple settings of the badge, like z-index and size, but no much more...
So far, i made two functions that set data-theme to light or dark mode at innit. Note that its neccessary assign the "light" because Google not include that by default.
function reCaptchaDark() {
document.addEventListener('DOMContentLoaded', (event) => {
recaptcha.setAttribute("data-theme", "dark");
})
}
function reCaptchaLight() {
document.addEventListener('DOMContentLoaded', (event) => {
recaptcha.setAttribute("data-theme", "light");
})
}
Then, for example, my web looks if user prefers a dark or a light theme, and set that configurations to the recaptcha bag:
(theme.onLoad = function() {
if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) {
reCaptchaDark();
toggleTheme();
}
else {
reCaptchaLight();
}
})();
Note that my code for toggle from dark to light is on the toggleTheme() function.
Keep doing magic: You should configure a class on the html tag or something else on your web for made the change between dark and light theme, and with that we now modify the src on the iframe so when we toggle dark/light mode ,with our button it changes:
theme.onclick = function() {
toggleTheme();
if (html.classList.contains('dark')) {
recaptcha.setAttribute("data-theme", "dark");
setTimeout(function() {
let iframes = document.querySelectorAll('iframe');
iframes[0].src = iframes[0].src.replace('&theme=light', '&theme=dark');
}, 0);
}
else {
recaptcha.setAttribute("data-theme", "light");
setTimeout(function() {
let iframes = document.querySelectorAll('iframe');
iframes[0].src = iframes[0].src.replace('&theme=dark', '&theme=light');
}, 0);
}
}
And here you go, the recaptcha badge change from dark to light "preassigned" themes by Google bad guys.
And last but not least, a function that updates the page to change if your theme is dark by default.
This update the LocalStorage
(function() {
if( window.localStorage ) {
if( !localStorage.getItem('firstLoad') ) {
localStorage['firstLoad'] = true;
window.location.reload();
}
else
localStorage.removeItem('firstLoad');
}
})();
You can use the class .grecaptcha-badge for some css changes, like opacity and box-shadow, -> (use !important)
Thats all, hope you can implement on your site
