Using icons in Bootstrap 4.5 - javascript

I'm trying to figure out how to use the icons in Bootstrap 4.5 via CSS. Are there any code examples you can point me to? Ideally I'd like to know what CSS declarations are needed to be able to use them like Font Awesome e.g.
<i class="fas fa-info-circle"></i>.
The documentation at bootstrap https://icons.getbootstrap.com/#usage is not sufficient for me to figure out how to use them in a similar fashion. In other words, I'd like to be able to use jquery to set a class on an object to add an icon dynamically but I don't understand the CSS I need to do this.

CSS:
.bi-headphones::before {
display: inline-block;
content: "";
background-image: url("data:image/svg+xml,%3Csvg width='1em' height='1em' viewBox='0 0 16 16' class='bi bi-headphones' fill='currentColor' xmlns='http://www.w3.org/2000/svg'%3E%3Cpath fill-rule='evenodd' d='M8 3a5 5 0 0 0-5 5v4.5H2V8a6 6 0 1 1 12 0v4.5h-1V8a5 5 0 0 0-5-5z'/%3E%3Cpath d='M11 10a1 1 0 0 1 1-1h2v4a1 1 0 0 1-1 1h-1a1 1 0 0 1-1-1v-3zm-6 0a1 1 0 0 0-1-1H2v4a1 1 0 0 0 1 1h1a1 1 0 0 0 1-1v-3z'/%3E%3C/svg%3E");
background-repeat: no-repeat;
background-size: 1rem 1rem;
width:1rem; height:1rem;
}
Usage:
<i class="bi-headphones"></i>
I use URl SVG encoder to prepare svg for css: https://yoksel.github.io/url-encoder/

i cant find in the doc that bootstrap icon is fontawesome icon
after you install it you use it as a svg like this one
<svg class="bi bi-app" width="1em" height="1em" viewBox="0 0 16 16" fill="currentColor" xmlns="http://www.w3.org/2000/svg">
<path fill-rule="evenodd" d="M11 2H5a3 3 0 0 0-3 3v6a3 3 0 0 0 3 3h6a3 3 0 0 0 3-3V5a3 3 0 0 0-3-3zM5 1a4 4 0 0 0-4 4v6a4 4 0 0 0 4 4h6a4 4 0 0 0 4-4V5a4 4 0 0 0-4-4H5z"/>
</svg>
or you can use it this way after you download the svg to you project
<img src="/assets/img/bootstrap.svg" alt="" width="32" height="32" title="Bootstrap">
or on your css
.bi::before {
display: inline-block;
content: "";
background-image: url("data:image/svg+xml,<svg viewBox='0 0 16 16' fill='%23333' xmlns='http://www.w3.org/2000/svg'><path fill-rule='evenodd' d='M8 9.5a1.5 1.5 0 1 0 0-3 1.5 1.5 0 0 0 0 3z' clip-rule='evenodd'/></svg>");
background-repeat: no-repeat;
background-size: 1rem 1rem;
}

SVG is not showing on my localhost Apache v3.3.0

I tried to use a Search Icon in my header section,h but it is not shown . I tried everything but still no chance !
I added AddType image/svg+xml .svg .svgz I tried AddType image/svg+xml svg svgz and a few other lines I found on the net but still no chance . Can someone tell me what exactly should I do now ? My other SVGs are shown however and It is very strange !

AND HERE IS MY SVG FILE :

Instead of using it as a background-image, you can just insert the svg-tag into your body:

I need to implement this as doughnut chart - I looked around for css/svg/canvas solutions but couldn't find any reliable way of doing it.
I know I could have fully rounded corners of each segment, but that's not what I'm looking for.
I would use this answer combined with this one
.palette {
--g:20px; /* The gap between shapes*/
--s:50px; /* the size*/
height: 300px;

filter: url('#goo');
}

SVG Filter: Only working in Chrome, not other browsers

Simple demo of bug here: https://codepen.io/mknepprath/pen/mKeObo
Open in Chrome to see how it should look.
Issues:
In Safari, the filter seems to not apply or only apply partially...
it's different.
In Firefox, nothing shows up at all - it seems to
hide the filter and the div that the filter is applied to.
How do I get this to work consistently across browsers?
html:
<svg class='a'>
<defs>
<filter id='hey'>
<feColorMatrix
type='matrix'
result='darken'
x='0'
y='0'
width='200px'
height='100px'
values='.2 .05 .05 0 .35
.05 .2 .05 0 .35
.05 .05 .2 0 .35
0 0 0 1 0'
/>
<feColorMatrix
type='matrix'
result='node'
x='0'
y='0'
width='200px'
height='100px'
values='1 0 0 0 0
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0'
/>
<feMerge>
<feMergeNode in='darken' />
<feMergeNode in='node' />
</feMerge>
</filter>
</defs>
</svg>
<div class='b' style='filter: url(#hey)'></div>
css:
.a {
display: none;
}
.b {
width: 200px;
height: 100px;
background: peachpuff;
}
Chrome accepts bad syntax and tries to make the best of it, Firefox generally does not.
Using display:none takes the SVG out of the DOM so the CSS can't find the style anymore. Make the SVG zero sized, put it below your content or use visbility: hidden
In SVG 1.1 at least, you shouldn't' be able to use "px", "em" etc. to dimension your filter elements. (And there should be no need to size your feColorMatrixes - sizes are autocalculated by default.)
.a {
width: 0;
height: 0;
}
.b {
width: 200px;
height: 100px;
background: peachpuff;
}
<svg class="a">
<defs>
<filter id="hey">
<feColorMatrix

Make a div that go somewhat curved

This question have been asked a billion times I think, but just another case.
How to make this with HTML / CSS (and, if no other option, JS - I'm thinking of canvas or SVG) :
Notes : the div should be able to contain a scrolling background image on the whole green part. And this should work on IE9+ and common mobile devices (default browser). Also, the space around the shape needs to stay transparent (no white element to create the rounded shape can be used)
What's the better option ?
CSS Implementation
You can create a border shape within a container and hide the unwanted parts. I have used view port sized units to be scalable. It can be further improved to your requirement by manipulating with the values.
body {
background: #F5F5F5;
}
.container {
height: 70vh;
overflow: hidden;
display: inline-block;
width: 30vh;
background: white;
margin: 0 10px;
box-shadow: 0 2px 2px 0 rgba(0, 0, 0, 0.14), 0 3px 1px -2px rgba(0, 0, 0, 0.2), 0 1px 5px 0 rgba(0, 0, 0, 0.12);
}
.curve {
background: transparent;
border: 20vh solid #7cc576;
border-radius: 35%;
height: 100vh;
transform: translateY(-20vh);
width: 50vh;
}
.container-left-curved {
transform: rotateY(180deg);
}
.container-right-curved {
transform: rotateY(0deg);
}
<div class="container container-left-curved">
<div class="curve">
</div>
</div>
<div class="container container-right-curved">
<div class="curve">
</div>
</div>
SVG Implementation
I saved your image and generated the optimized SVG code through Inkscape editor. This looks a lot better than a pure CSS solution.
body {
background: lightgray;
}

Finally, after looking for the good way to achieve that, here's my notes:
1. RaphaelJS
I think RaphaelJS makes it easy and offers extended compatibility (I tested on IE8 and IE7, it works, even if I don't need it) and easier manipulation.
Here's a live example : http://jsfiddle.net/bkfssykp/
As you can see, this is somewhat a SVG based solution :
paper.path("M0,0h259.478c0,0,42.939,36.419,42.939,88.694 c0,132.905,0,368.306,0,368.306H42.939c0,0,0-235.587,0-368.464C42.939,36.345,0,0,0,0z");
I just pasted the code of my svg shape directly into it. Now, I can play with it : animation, modification, etc.
2. SVG clip-path
My first attempt was an SVG image with a SVG clip-path, as said in the article mentionned by #Deepak : https://css-tricks.com/clipping-masking-css/
Here's a live example : http://jsfiddle.net/xptycnkg/3/
Still SVG : this looks like CSS clip-path, but applied on SVG element. Works on IE9.

Animated Ripples using jquery

I would like to create an animated visualisation (responsive if possible) where the ripples are originating from a central point and when those ripples reach outer nodes in a circle, those nodes create similar ripples of variable size.
So far, I have found these libraries:
https://github.com/mbostock/d3/wiki/Gallery
http://flare.prefuse.org/
But none of them seem to have exactly what I am after and they also seem like an overkill.
What is be the best approach to achieve this?
P.S: I am open to using Adobe's Edge Animate if it offers an easy solution since I create a lot of data visualisations for the new company I am working with.
I think the best approach would be either to use some CSS animations or possibly to use HTML5 canvas and JavaScript with requestAnimationFrame
here is an example of creating a ripple effect with CSS animations on CodePen
.ripple:before,.ripple:after {
content:'';
position:absolute;
}
.ripple:before {
-webkit-animation-delay:.2s;-moz-animation-delay:.2s;top:5px;left:25px;
}
.ripple:after {
-webkit-animation-delay:.8s;-moz-animation-delay:.8s;top:25px;left:0;
}
#-webkit-keyframes rip
{
0% {
box-shadow:0 0 0 0 transparent,
0 0 0 0 transparent,
0 0 0 0 transparent,
0 0 0 0 transparent;
}
5% {
box-shadow:0 0 0 0 #45c2c5,
0 0 0 0 rgba(255,255,255,0.4),
0 0 0 0 #45c2c5,
0 0 0 0 rgba(0,0,0,0.08);
}
100% {
box-shadow:0 0 40px 200px #45c2c5,
0 0 10px 210px transparent,
0 0 30px 220px #45c2c5,
0 0 5px 230px transparent;
}
}
