How to change the width of elements based on container? - javascript

Hi in my website I have one container with Registration form elements. Now I want to change the size of labels, Text fields and button based on the container size.
My requirement is The textboxes should be on the right of the labels (and expand up to 40px before the right border of the grey container - 40px is the container's padding anyway) when the width of the screen is >=1024px .
If the width of the screen is <1024, the textboxes should be under the labels and their width should be as long as that of the grey container minus the container's padding on the left and on the right side.
Please suggest me the way to do this.
I have also attached a screenshot:
Here background with grey color is the container in website.
.dnnForm .dnnFormItem {
clear: both;
width: 100%;
display: block;
position: relative;
text-align: left;
}
#media screen and (min-width: 1025px)
#rox-custom-box-06 .dnnForm {
width: 100%;
}
#media screen and (min-width: 1025px)
#rox-custom-box-06 .dnnFormInput, .password-strength-container, .password-strength {
display: inline-block;
width: 35% !important;
}

To accomplish this you are going to need to think a bit more granular in nature with your solution.
The Container &/or form will need to have specific CSS classes applied so that you can then make things work. You might also look at using Bootstrap or similar in your skin to assist as it looks like you are trying to make a responsive design, but without having any supporting framework.
Otherwise, a more detailed example with your HTML could assist.

How to set 100 % height without having a vertical scrollbar?

Context
I have a navbar with a fixed height. I want the space underneath to fill the rest of the screen vertically. I also need to have a fixed height because I have a container inside the page that has a list that is scrollable but without scrolling the whole page overflow: hidden
The Problem
When I set a height on all parent elements of 100% I get a vertical scrollbar. I found some answers on SO about "margin collapse" but nothing that could solve my problem.
100vh also won't work without having a scrollbar.
Here is the css for setup the height (#__next is just a div where next.js renders the page):
html,
body,
#__next {
height: 100%;
width: 100%;
}
The navbar is just a fixed pixel height, and the space below has height: 100%
Here is a screenshot that shows the vertical scrollbar:
I can't find any problems on the chrome inspector.
This is how it should look (design file):
Do you know how to solve this? I need to have both containers from screen "SippetPanel" and "SnippetContent" to take the remaining height without adding a scrollbar. It should also work to have a inner scrollbar with overflow hidden (later on when there are many items in the list like from design file)
Be aware that percentual heights refer to the height of the parent.
You can use calc() to solve your issue:
#__next{
height: calc(100% - navbarpx);
...
}
calc()
For the padding issue you can look into border-box.
I usually just try different vh values, that means 90vh, 95.5vh etc. so it all sits perfectly. You can try to meddle with body position: absolute etc., but that would push everything into the navbar, so then you would need to fix it with additional margin-top.
So the best solution I see is to try different vh values for the height and find the sweet spot. You will need to do the same for different phone types as well with media queries, but it shoudn't really be hard.
One of the ways is to use flex-box, it allows you to explicitly say(take all available height.
.body {
display: flex;
flex-direction: column;
}
.navbar {
flex: 30px 0 0;
/* 30px height and do not grow or shint */
background: red;
}
.content {
flex-grow: 1;
/* take all available space */
background: blue;
}
.body, html, body {
width: 100%;
height: 100%;
}
<div class="body">
<div class="navbar"></div>
<div class="content"></div>
</div>

Unable to scroll mobile dropdown menu inside of fixed header

So I made a fixed dropdown menu that changes to a hamburger menu for mobile. Everything works fine on desktop but on mobile I'm unable to scroll the menu items. I have tried a plethora of suggested fixes for this but none of them fix my issue. Most of the fixes I've come across have included some form of the following but have not worked:
max-height: 300px;
overflow-y: scroll;
Here is a fiddle of what I have right now:
https://jsfiddle.net/doitliketyler/2gqd0hLs/3/
The black square is the mobile hamburger button. Does anyone know how to get this working properly and smoothly for mobile? Any help would be greatly appreciated. Thanks so much.
A position of static will prevent scrolling.
So to fix this, you have to set your menu to a position of something like relative for mobile.
So for the .header selector inside the #media only screen and (max-width:960px) media query, set the position to relative.
#media only screen and (max-width: 960px) {
.header {
padding-bottom: 0;
position: relative;
}
}
Edit 1:
To keep the fixed menu, one option is to set the dropdown portion to be a position of absolute with an overflow-y.
#media only screen and (max-width: 960px)
.header .header__column--navigation {
margin-top: 80px;
position: absolute; //Added
min-height: calc(100vh - 110px); //Added: set the second parameter of calc to the height of your header. ex: https://c.flm.pw/2018-06/6oiip.png
height: 100%; //Added: Tell the absolute div to take up as much height as it needs.
overflow-y: auto; //Added: Make the absolute div have the ability to scroll, but hide the scrollbar when it doesn't.
}

Removing vertical white space between divs, especially after hitting a breakpoint

I'm working on a responsive page design at the moment and I'm running into an issue with white-space between the divs, especially after hitting breakpoints.
body, html {
padding: 0;
margin: 0;
}
.header {
padding-top: 5px;
background-color: red;
width: 100%;
}
.sub-header {
padding: 5px;
margin: 0px;
background-color: yellow;
width: 100%;
}
.main-content {
padding: 5px;
background-color: blue;
width: 100%;
}
.footer {
position: absolute;
bottom: 0;
padding: 5px;
background-color: green;
width: 100%;
}
#media screen and (max-width: 320px) {
.sub-header {
display: none;
}
}
}
<div class="header">Header
<div class="sub-header">Sub-Header</div>
</div>
<div class="main-content">Auto adjust size</div>
I want to have the blue div take up the remaining space in this white space, as well as after the sub-header is removed at the break point.
<div class="footer">footer</div>
Here's a quick mock up of what I'm experiencing: http://jsfiddle.net/gaych7vp/6/
I understand what I have to do in order to make it take up the remainder of the white space before it hits a breakpoint (I'm assuming just tweaking the height values), but how would I go about making the blue div take up the remaining white space that gets created when the yellow div gets hidden after hitting the breakpoint?
I'm still really new to javascript but from other answers I've read it could be done by creation a function that finds the height of the browser and then subtracts it from the other divs. Is that possible and if so, how could I accomplish that?
Use position:absolute with different top values
.main-content {
position:absolute;
top:51px;
bottom:0px;
}
and
#media screen and (max-width: 320px) {
.main-content {
top: 23px;
}
}
fiddle
Another approach is using display:table and display:table-row
body, html{
width:100%;
height: 100%;
}
body{
display:table;
}
.main-content {
width: 100%;
height: 100%;
display:table-row;
}
fiddle
Make a div fill the height of the remaining screen space
You can use calc on the .main-content div to calculate the size, but you would need to set the heights of the header, footer, and subheader divs. Seems to me though you could just give the body a background color of blue, and achieve the same thing?
Change
#media screen and (max-width: 320px) {
.sub-header {
display: none;
}
}
to
#media screen and (max-width: 320px) {
.sub-header {
visibility: hidden;
}
}
I think this is what you meant. Fiddle.
There's no need for a JavaScript solution here.
The white area is caused because you are using position: absolute to force the footer to the bottom of the window, regardless of the content.
This isn't the normal way to achieve this, you'll run into issues later on when you do add content to your main-content div. You'll find that the footer will be positioned over this content (this will also happen if you shrink the window vertically).
I think what you'd like to do, is give the main-content div a min-height:, this way, the page won't collapse and look terrible if there is little content, but it will stretch naturally when more content is added.
You can also and remove the position: absolute from the footer div.
Here is a demonstration:
http://jsfiddle.net/t46aopas/
** UPDATE **
If you'd like a dynamic solution, I've created a heavily annotated JavaScript example here: http://jsfiddle.net/nahgdkaw/
(I included lots of comments since you said you were new to JavaScript ;) )
That should hopefully help you along the way a little.
Be aware that if the content inside the .main-content div is larger than the .main-content div area, the div will NOT expand to accommodate it.
You can however use the code provided and add in an if statement to, before resizing the .main-content div, check if the .main-content content
is larger than the available area (you may need to add a wrapper div around the .main-content content). If so, then resize the .main-content div to match the .main-content content height (otherwise, perform the resize as it currently is).
(Also, I strongly advise against using HTML tables for anything other than tabular data)

Image max-height

I have got a tiny problem, im creating a website and i want to give an image a max-height. The image may only have the same height of another div.
You can check the layout here: http://bit.ly/1OAGsLR
Its about the 1920x1080 image, and i needs to be the same height as the div with class box left to it. If right the image should scale well.
But im trying all i know but i dont get it working, can someone get this working with CSS or do i need to use Javascript for this?
Thanks in advance!
Your image is looking the way you want when the screen width is at or above 1400px. You should consider using css media queries to move or adjust the image at different screen widths. Your layout could easily be handled using a css framework like foundation or bootstrap which would take care of css media query breakpoints for you.
If you are intentionally trying to not use a css framework, I'd check out this css media queries tutorial to get you started.
You need to make your container div wider.
Your container is 1200px wide, and your boxes are 560 + 40 padding wide each.
That means that the max width of you image is 560px.
Now to conserve it's aspect ratio of 16:9, the max height of the image is 560 / 16 * 9 = 315 pixels.
Okay, your main problem is that heights don't like to be defined this way. I have a solution for you that will 'solve' this issue, but its not very pretty and you might want to look into doing this with javascript anyhow. Below is a very rough example mockup.
body > div {
width: 100%;
max-width: 500px;
background: green;
padding: 10px;
position: relative;
}
body > div > div {
width: 50%;
padding: 20px;
}
body > div > img {
position: absolute;
right: 20px;
top: 20px;
max-width: 50%;
/* make sure to fall back to 80% so theres at least some gutter for older browsers */
max-height: 80%;
/* use calc to make the image the height of the relative parent minus padding */
max-height: calc(100% - 40px);
}
<div>
<div>Push<br />Push<br />Push<br />Push<br />Push<br /></div>
<img src="http://placehold.it/350x150" />
</div>
In short, this will place your image to the right of your box, give it a max-height (because positioning can do that) and a max-width (so smaller screen sizes don't freak out).
Now you could easily translate this a more general system where .box + .boxget a absolute position, or you could define a class for the box that has to push content and add that to the first box, making all other boxes absolute.
I fixed it by using JS, im using the following script:
<script type="text/javascript">
function changeheight(){
var Height = document.getElementById('box').clientHeight;
document.getElementById('imagebox').style.height = Height+'px';
}
</script>

Centering Two Dynamic-Width Divs On The Same Line and

Okay I apologize if this is a repeat - but I couldn't find any working answers anywhere.
I want to have two divs (50% width each) side by side... so a left and a right - inside of a content div (see photo below).
I want them to have min-widths at 300px and once the page gets smaller than 600px (which is when both divs will reach their mins) I want to divs to wrap.. so one on top the other.
I've tried to do that here: fiddle but am having problems.
Here is EXACTLY what I want:
You're making things hard for yourself! This can be done quickly and easily with inline-blocks. Have a nice JSfiddle.
Lets explain the code:
.wrapper
{
text-align: center; /* specifies that the inline-blocks (which are treated
like text here) will be centered. */
font-size: 0; /* Explained later */
max-width: 1000px; /* Your desired max-width */
position: relative; /* These two lines center your wrapper in the page. */
margin: 0 auto;
}
Now for the inside 50% elements:
.left, .right{
display: inline-block; /* This will treat these divs like a text element.
This will work with the parent's "text-align: center" to center the element. */
min-width: 300px;
width: 50%;
font-size: 16px; /* Explained below */
vertical-align: text-top; /* Explained below */
}
You might be wondering why font-size is included. It is because with this method comes a little quirk - if a font size is kept at default, the div's will have an annoying gap between them that can not be eliminated with margin.
However, adding font-size: 0; to the parent element eliminates this gap. It's weird, and you then have to specify the font-size for your children elements, but it's well worth it for the ease of use.
But there's still a problem - the blue element is pushed down, and isn't flush on the top. This can be remedied with vertical-align: text-top; This will make sure all Div elements are aligned by the tops, so they lay in a more pleasant pattern. This is just another little quirk to remember when using inline-blocks. I know it seems like a lot of things to fix just for something this simple, but compared to your other options using inline-block is the cleanest and easiest way of going about this. (Though if you prefer, jshanley offers a very good alternative using float elements)
Also, because these children are now treated like text, they will automatically reposition themselves when the window gets too small! No media-queries needed. Yay.
Good luck.
Instead of using inline-block which causes some sizing quirks, you can use block elements, and float both .left and .right to the left, giving each a width of 50%.
Then to make them stack you need to do a little calculating. Since you specified that the wrapper is 80% of the page width, and the break point for the content is at 600px (each element 300px) the page's breakpoint would be at 750px since 80% of 750 is 600.
You can make a media query that will only apply styles when the page width is less than 750px and set .left and .right to width 100% to make them stack.
#media only screen and (max-width: 750px) {
.left, .right {
width: 100%;
}
}
It's very simple to implement, and gives a good result, here's the fiddle.
I think both #jshanley and #emn178's answers do the trick, but I want to point something out:
The display: inline-block; css property doesn't work with float: right nor float: left, since when you use the float property, it ALWAYS automatically set the display property to block.
Since you're doing this:
.right{
min-width:100px;
background-color:purple;
height:100%;
margin-left:50%;
display:inline-block;
}
The display: inline-block; property is doing nothing.
left and right could have same layout, so I add a class block.
To use float:left and width:50%, it should work.
http://jsfiddle.net/emn178/mzbku/7/
I add media query, it should be what you want.
But you need to calculate how to set the size.
