Webkit scrolling too much? - javascript

I have some content which can have only specific height (no more), and I added some scroll on that content.
This is my CSS:
.value {
max-height: 60px;
overflow-y: auto;
color: black;
font-size: 16px;
}
/* width */
.value::-webkit-scrollbar {
width: 3px;
}
/* Track */
.value::-webkit-scrollbar-track {
box-shadow: inset 0 0 5px rgb(163, 163, 163);
border-radius: 5px;
}
/* Handle */
.value::-webkit-scrollbar-thumb {
background: linear-gradient(60deg, #b95aca, #8c15ad);
border-radius: 5px;
}
And This is my Subtitle content:
<div
class="value"
*ngIf="courseData.sub_title"
> {{courseData.sub_title}}
</div>
This is the image:
So, when I want to scroll down or up using mouse wheel it's scrolling too much and user can not be able read full text (part of text was going up or down with scrolling).
How can I change scroll step?

Change color of bootstrap scrollbar - scrollspy?

I have a working scrollbar using Bootstrap scrollspy but can't figure out how to change the color of the bar (thumb?).
HTML:
<body>
<div class="container, scrollbar" id="myScrollspy">
<div class="panel-group" id="accordion">
...
CSS:
.scrollbar::-webkit-scrollbar-track
{
border-radius: 10px;
background-color: #F5F5F5;
}
.scrollbar::-webkit-scrollbar
{
width: 12px;
background-color: #F5F5F5;
}
.scrollbar::-webkit-scrollbar-thumb
{
border-radius: 10px;
background-color: #D62929;
}
This isn't changing the color of the bar in the scrollbar. Is there something different in the way bootstrap styles a scrollbar?
If you need to change the color of scrollbar thumb this will be helpful.Be more specific with a sample code or a screenshot.
/* width */
::-webkit-scrollbar {
width: 10px;
}
/* Track */
::-webkit-scrollbar-track {
background: #f1f1f1;
}
/* Handle */
::-webkit-scrollbar-thumb {
background: #888;
}
/* Handle on hover */
::-webkit-scrollbar-thumb:hover {
background: #555;
}

Enforce key size on virtual keyboard

This is the layout I am trying to achieve: https://jsfiddle.net/h0oa3Lps/ All keys are the same size.
In my application I have this code. The js is at the bottom of my jade file:
$('.keyboard')
.keyboard({
layout: 'custom',
customLayout: {
'default' : [
'1 2 3 {c}',
'4 5 6 {b}',
'7 8 9 {dec}',
'{left} {right} 0 {a}'
]
},
maxLength : 6,
restrictInput : true,
useCombos : false,
acceptValid : true,
validate : function(keyboard, value, isClosing){
// only make valid if input is between 0 and 100 inclusive
return value >= 0.0 && value <= 100.0;
}
})
.addTyping();
When using css/keyboard.min.css, the left arrow, right arrow and backspace keys are slightly larger than the other keys. Also the text positioning is off. Image:
If I switch to css/keyboard-basic.min.css the arrow keys are the same size as regular keys but the esc, backspace, and accept keys are twice the size as the regular keys. Also this takes up half of the screen (since it's not using the jquery-ui positioning). Image:
How do I enforce uniform key size?
If it makes any difference I am using Node, Express and Foundation v5.5.3 plus I have just updated to the latest versions of jQuery, jQuery-ui and jQuery.keyboard.
To fix this issue I copied the unminified css of keyboard.css to a keyboard-butchered.css. I then started experimenting with the styles in keyboard-basic.css and eventually came up with the following that partially answered my question:
.ui-keyboard {
/* adjust overall keyboard size using "font-size" */
font-size: 28px; /* increase button size for small screen */
text-align: center;
background: #fefefe;
border: 1px solid #aaa;
padding: 4px;
/* include the following setting to place the
keyboard at the bottom of the browser window */
left: 0px;
top: auto;
/*position: fixed;*/
position: absolute;
white-space: nowrap;
overflow-x: auto;
/* see issue #484 */
-ms-touch-action: manipulation;
touch-action: manipulation;
}
I then mixed in the style for the keyboard button. This gives the correct style as seen in the jsfiddle demo (but jumbo sized).
.ui-keyboard-button {
border: 1px solid #aaa;
padding: 0 0.5em;
margin: 1px;
min-width: 3em;
height: 3em;
line-height: 3em;
vertical-align: top;
font-family: Helvetica, Arial, sans-serif;
color: #333;
text-align: center;
border-radius: 5px;
-webkit-box-shadow: 1px 1px 3px 0 rgba(0, 0, 0, 0.5);
box-shadow: 1px 1px 3px 0 rgba(0, 0, 0, 0.5);
background: white;
background-image: -webkit-linear-gradient(-90deg, white 0%, #e3e3e3 100%);
background-image: linear-gradient(-90deg, white 0%, #e3e3e3 100%);
cursor: pointer;
overflow: hidden;
-moz-user-focus: ignore;
}

JS newsticker issues

I have a site that wanted a TV credits-style ticker & I just went back to revisit & check up on them & noticed that the display was starting to break down. I'm hoping that those of you more experienced JS veterans can help me figure out where I've gone wrong, here.
My JS is as follows:
$('.sidescroll').totemticker({
row_height : '120px',
next : '#ticker-next',
previous : '#ticker-previous',
stop : '#stop',
start : '#start',
mousestop : true
});
jQuery(".sidescroll li").append("<hr />");
and the my CSS for it is as follows:
.sidescroll {
height: 100% !important;
display: block;
}
.sidescroll li {
margin: 10px;
text-align: left;
height: 120px;
}
.sidescroll hr {
height: 3px;
border: 0;
box-shadow: inset 0 3px 3px -3px rgba(92, 71, 112, 0.75);
}
.sidescroll li a {
font-family: 'lulo' !important;
}
.sidescroll li a:hover {
text-decoration: none;
color: #5c4770;
}
The ticker is for their blog posts, sort of a running list of posts, which is being pulled by the list category plugin & is limited to 20 characters for the excerpt. The issue that I noticed was that the horizontal row is starting to interact with a couple of the posts, which was not the case when the site was set up.
Turns out it's fairly simple. There is sometimes too much content in the boxes and they overflow into the one below. Either too much text or the word wrapping is splitting over too many lines.
Bonus (completely optional)
We can elegantly suppress this behavior (assuming the use of CSS3 to generate a gradient).
First we modify the javascript to insert the horizontal line as first child, then we insert a div with a class as a last child:
jQuery(".sidescroll li").prepend('<hr />');
jQuery(".sidescroll li").append('<div class="fadeToWhite"></div>');
Then we modify the css:
.sidescroll {
height: 100% !important;
display: block;
}
.sidescroll li {
margin: 10px;
text-align: left;
height: 120px;
/* additions: */
position: relative;
overflow: hidden;
}
.sidescroll hr {
height: 3px;
border: 0;
box-shadow: inset 0 3px 3px -3px rgba(92, 71, 112, 0.75);
}
.sidescroll li a {
font-family: 'lulo' !important;
}
.sidescroll li a:hover {
text-decoration: none;
color: #5c4770;
}
/* additions */
.sidescroll li div.fadeToWhite {
width: 100%;
height: 20px;
position: absolute;
bottom: 0;
background: linear-gradient(transparent, white);
}
This will hide any overflowing text while turning the additional div into a fade-to-white bar at the bottom of each list element to avoid a hard text-cut.

div display none breaks style

I have a textarea for comments and a button to show or hide it (toggle). If I want to hide it by default (display: none) when I click the button to show it, the style is broken but if it's not hidden (display: block) I can click without problems, the style will be fine.
html:
<a id="1" class="comment_button a_button" title="Dejar un comentario">Comentar</a>
<div id="hide_1" class="rows" style="display: none;">
<ul id="UL_101">
<!-- New comment row -->
<li class="newComment_row">
<div class="userComments_photo">
<img class="photo" src="/images/profile/' . $_SESSION['photo'] .'" alt="" />
</div>
<textarea id="' . $imgID . '" class="textarea" rows="1" placeholder="Escribe un comentario..." title="Escribe un comentario..."></textarea>
</li>
</ul>
</div>
css:
.rows {
height: auto;
width: 494px;
background: rgb(246, 247, 248) none repeat scroll 0% 0% / auto padding-box border-box;
border-radius: 0 0 3px 3px;
margin: 8px -12px -12px;
}
#UL_101 {
width: 494px;
list-style: none outside none;
margin: 0px;
padding: 0px;
border-top: 1px solid rgb(225, 226, 227);
}
/* li */
.newComment_row {
height: auto;
position: relative;
width: 470px;
background: rgb(246, 247, 248) none repeat scroll 0% 0% / auto padding-box border-box;
border-radius: 0 0 2px 2px;
list-style: none outside none;
margin: 0px 12px;
padding: 4px 0px 8px 0px;
}
.textarea {
resize: none;
width: 416px;
font: normal normal normal 12px/15.3599996566772px Helvetica, Arial, 'lucida grande', tahoma, verdana, arial, sans-serif;
position: initial;
padding: 8px 3px 0 3px;
margin: 0 7px;
overflow: hidden;
}
and jquery:
// show rows
$('.comment_button').on('click', function () {
$('#hide_' + this.id).slideToggle('fast');
});
function h(e) {
$(e).css({
'height': 'auto',
'overflow-y': 'hidden'
}).height(e.scrollHeight);
}
$('textarea').each(function () {
h(this);
}).on('input', function () {
h(this);
});
display: none breaks the style: http://jsfiddle.net/cb41hmpo/
display: block does not break it: http://jsfiddle.net/cb41hmpo/1/
It seems the problem is the auto-height function... Is there a way to fix this?
I'd like to keep that textarea size if possible, whatever the changes are.
It's not a big deal but if display is set to block and I click the button, the textarea placeholder text appears some fuzzy or blurred for a second, is that a normal thing or can it be fixed?
If we go through your code
function h(e) {
alert(e.scrollHeight);
$(e).css({
'height': 'auto',
'overflow-y': 'hidden'
}).**height(e.scrollHeight)**;
}
If you look at the bold section here you are assigning the scrollHeight to $e. If we do an alert we can see that the height of textarea when the parent div is hidden is 0 and it is 23 when the div is shown it is 23 px. Now in the (star marked -->height(e.scrollHeight) text we are assigning explicitly that height to the textarea (bold text). Hence, it is smaller in size. Hence your height auto is not coming into picture as you are assigning height by e.scrollHeight.
Try removing the bold text from both the snippets. The result you will get will be the same.
Hope this be of some help.
Happy Learning :)

Adding a rounded similar to border-radius to outline [duplicate]

Is there any way of getting rounded corners on the outline of a div element, similar to border-radius?
I had an input field with rounded border and wanted to change colour of focus outline. I couldn't tame the horrid square outline to the input control.
So instead, I used box-shadow. I actually preferred the smooth look of the shadow, but the shadow can be hardened to simulate a rounded outline:
input, input:focus {
border: none;
border-radius: 2pt;
box-shadow: 0 0 0 1pt grey;
outline: none;
transition: .1s;
}
/* Smooth outline with box-shadow: */
.text1:focus {
box-shadow: 0 0 3pt 2pt cornflowerblue;
}
/* Hard "outline" with box-shadow: */
.text2:focus {
box-shadow: 0 0 0 2pt red;
}
<input class="text1">
<br>
<br>
<input type=text class="text2">
I usually accomplish this using the :after pseudo-element:
of course it depends on usage, this method allows control over individual borders, rather than using the hard shadow method.
you could also set -1px offsets and use a background linear gradient (no border) for a different effect once again.
body {
margin: 20px;
}
a {
background: #999;
padding: 10px 20px;
border-radius: 5px;
text-decoration: none;
color: #fff;
position: relative;
border: 2px solid #000;
}
a:after {
content: '';
display: block;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
border-radius: 5px;
border: 2px solid #ccc;
}
Button
Similar to Lea Hayes above, but here's how I did it:
div {
background: #999;
height: 100px;
width: 200px;
border: #999 solid 1px;
border-radius: 10px;
margin: 15px;
box-shadow: 0px 0px 0px 1px #fff inset;
}
<div></div>
No nesting of DIVs or jQuery necessary, Altho for brevity I have left out the -moz and -webkit variants of some of the CSS. You can see the result above
Use this one:
box-shadow: 0px 0px 0px 1px red;
I wanted some nice focus accessibility for dropdown menus in a Bootstrap navbar, and was pretty happy with this:
a.dropdown-toggle:focus {
display: inline-block;
box-shadow: 0 0 0 2px #88b8ff;
border-radius: 2px;
}
Visit Stackoverflow
We may see our wishes soonish by setting outline-style: auto It's on WebKits radar: http://trac.webkit.org/changeset/198062/webkit
See ya in 2030.
You're looking for something like this, I think.
div {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid black;
background-color: #CCC;
height: 100px;
width: 160px;
}
Edit
There is a Firefox-only -moz-outline-radius properly, but that won't work on IE/Chrome/Safari/Opera/etc. So, it looks like the most cross-browser-compatible way* to get a curved line around a border is to use a wrapper div:
div.inner {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid black;
background-color: #CCC;
height: 100px;
width: 160px;
}
div.outer {
display: inline-block;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid red;
}
<div class="outer">
<div class="inner"></div>
</div>
*aside from using images
Firefox 88+: border-radius
From April 2021 you will be able to use a simple CSS for Firefox:
.actual {
outline: solid red;
border-radius: 10px;
}
.expected {
border: solid red;
border-radius: 10px;
}
In Firefox 88+,
<span class="actual">this outline</span>
should look like
<span class="expected">this border</span>
Current behaviour in Firefox 86.0:
Webkit: no solution
Using outline-style: auto will tell the «user agent to render a custom outline style»: see [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/outline-style(.
Webkit-based browsers will then draw the outline over the border, when you use outline-style: auto. It's difficult to style it properly.
.actual {
outline: auto red;
border-radius: 10px;
}
.expected {
border: solid red;
border-radius: 10px;
}
In WebKit browsers (Chrome, Edge),
<span class="actual">this outline</span>
should look close to
<span class="expected">this border</span>
Current behaviour in Chrome 89.0:
More information
From Firefox 88 (to be released April 20 2021), outline will follow the shape of border-radius.
The current -moz-outline-radius will become redundant and will be removed.
See MDN's entry about -moz-outline-radius:
From Firefox 88 onwards, the standard outline property will follow the shape of border-radius, making -moz-outline-radius properties redundant. As such, this property will be removed.
(Feb 2023)
As far as I know, the Outline radius is only supported by Firefox and Firefox for android.
-moz-outline-radius: 1em;
I just found a great solution for this, and after looking at all the responses so far, I haven't seen it posted yet. So, here's what I did:
I created a CSS Rule for the class and used a pseudo-class of :focus for that rule. I set outline: none to get rid of that default light-blue non-border-radius-able 'outline' that Chrome uses by default. Then, in that same :focus pseudo-class, where that outline no longer exists, I added my radius and border properties. Leading to the following
outline: none;
border-radius: 5px;
border: 2px solid maroon;
to have a maroon-colored outline with a border radius that now appears when the element is tab-selected by the user.
If you want to get an embossed look you could do something like the following:
.embossed {
background: #e5e5e5;
height: 100px;
width: 200px;
border: #FFFFFF solid 1px;
outline: #d0d0d0 solid 1px;
margin: 15px;
}
.border-radius {
border-radius: 20px 20px 20px 20px;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
-khtml-border-radius: 20px;
}
.outline-radius {
-moz-outline-radius: 21px;
}
<div class="embossed"></div>
<div class="embossed border-radius"></div>
<div class="embossed border-radius outline-radius">-MOZ ONLY</div>
I have not found a work around to have this work in other browsers.
EDIT: The only other way you can do this is to use box-shadow, but then this wont work if you already have a box shadow on that element.
Chrome 94.0+
I tested it in chrome 94.0 and it seems that the outline property honors the border-radius now.
.outline {
outline: 2px solid red;
}
.border {
border: 2px solid red;
}
.outline-10 {
border-radius: 10px;
}
.border-2 {
border-radius: 2px;
}
.outline-2 {
border-radius: 2px;
}
.border-10 {
border-radius: 10px;
}
.outline-50 {
border-radius: 50%;
}
.border-50 {
border-radius: 50%;
}
.circle {
display: inline-block;
width:50px;
height: 50px;
}
<strong>Test this in chrome 94.0+</strong>
<br/><br/>
border-radius: 2px
<span class="outline outline-2">outline</span>
<span class="border border-2">border</span>
<br/><br/>
border-radius: 10px
<span class="outline outline-10">outline</span>
<span class="border border-10">border</span>
<br/><br/>
border-radius: 50%
<span class="outline outline-50">outline</span>
<span class="border border-50">border</span>
<span class="outline circle outline-50">outline</span>
<span class="border circle border-50">border</span>
As others have said, only firefox supports this. Here is a work around that does the same thing, and even works with dashed outlines.
.has-outline {
display: inline-block;
background: #51ab9f;
border-radius: 10px;
padding: 5px;
position: relative;
}
.has-outline:after {
border-radius: 10px;
padding: 5px;
border: 2px dashed #9dd5cf;
position: absolute;
content: '';
top: -2px;
left: -2px;
bottom: -2px;
right: -2px;
}
<div class="has-outline">
I can haz outline
</div>
No. Borders sit on the outside of the element and on the inside of the box-model margin area. Outlines sit on the inside of the element and the box-model padding area ignores it. It isn't intended for aesthetics. It's just to show the designer the outlines of the elements. In the early stages of developing an html document for example, a developer might need to quickly discern if they have put all of the skeletal divs in the correct place. Later on they may need to check if various buttons and forms are the correct number of pixels apart from each other.
Borders are aesthetic in nature. Unlike outlines they are actually apart of the box-model, which means they do not overlap text set to margin: 0; and each side of the border can be styled individually.
If you're trying to apply a corner radius to outline I assume you are using it the way most people use border. So if you don't mind me asking, what property of outline makes it desirable over border?
COMBINING BOX SHADOW AND OUTLINE.
A slight twist on Lea Hayes answer
I found
input[type=text]:focus {
box-shadow: 0 0 0 1pt red;
outline-width: 1px;
outline-color: red;
}
gets a really nice clean finish. No jumping in size which you get when using border-radius
There is the solution if you need only outline without border. It's not mine. I got if from Bootstrap css file. If you specify outline: 1px auto certain_color, you'll get thin outer line around div of certain color. In this case the specified width has no matter, even if you specify 10 px width, anyway it will be thin line. The key word in mentioned rule is "auto".
If you need outline with rounded corners and certain width, you may add css rule on border with needed width and same color. It makes outline thicker.
I was making custom radio buttons and the best customisable way i've found is using pseudo elements like this: Codepen
/*CSS is compiled from SCSS*/
.product-colors {
margin-bottom: 1em;
display: flex;
align-items: center;
}
.product-colors label {
position: relative;
width: 2.1em;
height: 2.1em;
margin-right: 0.8em;
cursor: pointer;
}
.product-colors label:before {
opacity: 0;
width: inherit;
height: inherit;
padding: 2px;
border: 2px solid red;
border-radius: 0.2em;
content: "";
position: absolute;
z-index: 1;
background: transparent;
top: -4px;
left: -4px;
}
.product-colors input {
position: absolute;
opacity: 0;
width: 0;
height: 0;
}
.product-colors input:checked + label:before, .product-colors input:focus + label:before {
opacity: 1;
}
<div class="product-colors">
<input type="radio" name="cs" id="cs1" value="black">
<label for="cs1" style="background:black"></label>
<input type="radio" name="cs" id="cs2" value="green">
<label for="cs2" style="background:green"></label>
<input type="radio" name="cs" id="cs3" value="blue">
<label for="cs3" style="background:blue"></label>
<input type="radio" name="cs" id="cs4" value="yellow">
<label for="cs4" style="background:yellow"></label>
</div>
clip-path: circle(100px at center);
This will actually make clickable only circle, while border-radius still makes a square, but looks as circle.
The simple answer to the basic question is no. The only cross-browser option is to create a hack that accomplishes what you want. This approach does carry with it certain potential issues when it comes to styling pre-existing content, but it provides for more customization of the outline (offset, width, line style) than many of the other solutions.
On a basic level, consider the following static example (run the snippent for demo):
.outline {
border: 2px dotted transparent;
border-radius: 5px;
display: inline-block;
padding: 2px;
margin: -4px;
}
/* :focus-within does not work in Edge or IE */
.outline:focus-within, .outline.edge {
border-color: blue;
}
br {
margin-bottom: 0.75rem;
}
<h3>Javascript-Free Demo</h3>
<div class="outline edge"><input type="text" placeholder="I always have an outline"/></div><br><div class="outline"><input type="text" placeholder="I have an outline when focused"/></div> *<i>Doesn't work in Edge or IE</i><br><input type="text" placeholder="I have never have an outline" />
<p>Note that the outline does not increase the spacing between the outlined input and other elements around it. The margin (-4px) compensates for the space that the outlines padding (-2px) and width (2px) take up, a total of 4px.</p>
Now, on a more advanced level, it would be possible to use JavaScript to bootstrap elements of a given type or class so that they are wrapped inside a div that simulates an outline on page load. Furthermore, event bindings could be established to show or hide the outline on user interactions like this (run the snippet below or open in JSFiddle):
h3 {
margin: 0;
}
div {
box-sizing: border-box;
}
.flex {
display: flex;
}
.clickable {
cursor: pointer;
}
.box {
background: red;
border: 1px solid black;
border-radius: 10px;
height: 5rem;
display: flex;
align-items: center;
text-align: center;
color: white;
font-weight: bold;
padding: 0.5rem;
margin: 1rem;
}
<h3>Javascript-Enabled Demo</h3>
<div class="flex">
<div class="box outline-me">I'm outlined because I contain<br>the "outline-me" class</div>
<div class="box clickable">Click me to toggle outline</div>
</div>
<hr>
<input type="text" placeholder="I'm outlined when focused" />
<script>
// Called on an element to wrap with an outline and passed a styleObject
// the styleObject can contain the following outline properties:
// style, width, color, offset, radius, bottomLeftRadius,
// bottomRightRadius, topLeftRadius, topRightRadius
// It then creates a new div with the properties specified and
// moves the calling element into the div
// The newly created wrapper div receives the class "simulated-outline"
Element.prototype.addOutline = function (styleObject, hideOutline = true) {
var element = this;
// create a div for simulating an outline

In closing, let me reiterate, that implementing this approach may require more styling than what I have included in my demos, especially if you have already styled the element you want outlined.
outline-style: auto has had full browser support for ages now.
Shorthand is:
outline: auto blue;
This let's you set a custom color, but not a custom thickness, unfortunately (although I think the browser default thickness is a good default).
You can also set a custom outline-offset when using outline-style: auto.
outline: auto blue;
outline-offset: 0px;
you can use box-shadow instead of outline like this
box-shadow: 0 0 1px #000000;
border-radius: 50px;
outline: none;
Try using padding and a background color for the border, then a border for the outline:
.round_outline {
padding: 8px;
background-color: white;
border-radius: 50%;
border: 1px solid black;
}
Worked in my case.
I just set outline transparent.
input[type=text] {
outline: rgba(0, 0, 0, 0);
border-radius: 10px;
}
input[type=text]:focus {
border-color: #0079ff;
}
I like this way.
.circle:before {
content: "";
width: 14px;
height: 14px;
border: 3px solid #fff;
background-color: #ced4da;
border-radius: 7px;
display: inline-block;
margin-bottom: -2px;
margin-right: 7px;
box-shadow: 0px 0px 0px 1px #ced4da;
}
It will create gray circle with wit border around it and again 1px around border!
