I have searched this website to find progress bars, but the ones I have been able to found show animated circles that go to the full 100%.
I would like it to stop at certain percentages like in the screenshot below. Is there any way I can do that using only CSS?
I created a fiddle using only CSS.
.wrapper {
width: 100px; /* Set the size of the progress bar */
height: 100px;
position: absolute; /* Enable clipping */
clip: rect(0px, 100px, 100px, 50px); /* Hide half of the progress bar */
}
/* Set the sizes of the elements that make up the progress bar */
.circle {
width: 80px;
height: 80px;
border: 10px solid green;
border-radius: 50px;
position: absolute;
clip: rect(0px, 50px, 100px, 0px);
}
/* Using the data attributes for the animation selectors. */
/* Base settings for all animated elements */
div[data-anim~=base] {
-webkit-animation-iteration-count: 1; /* Only run once */
-webkit-animation-fill-mode: forwards; /* Hold the last keyframe */
-webkit-animation-timing-function:linear; /* Linear animation */
}
.wrapper[data-anim~=wrapper] {
-webkit-animation-duration: 0.01s; /* Complete keyframes asap */
-webkit-animation-delay: 3s; /* Wait half of the animation */
-webkit-animation-name: close-wrapper; /* Keyframes name */
}
.circle[data-anim~=left] {
-webkit-animation-duration: 6s; /* Full animation time */
-webkit-animation-name: left-spin;
}
.circle[data-anim~=right] {
-webkit-animation-duration: 3s; /* Half animation time */
-webkit-animation-name: right-spin;
}
/* Rotate the right side of the progress bar from 0 to 180 degrees */
#-webkit-keyframes right-spin {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(180deg);
}
}
/* Rotate the left side of the progress bar from 0 to 360 degrees */
#-webkit-keyframes left-spin {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(360deg);
}
}
/* Set the wrapper clip to auto, effectively removing the clip */
#-webkit-keyframes close-wrapper {
to {
clip: rect(auto, auto, auto, auto);
}
}
<div class="wrapper" data-anim="base wrapper">

Or this beautiful round progress bar with HTML5, CSS3 and JavaScript.
What about that?
HTML
<div class="chart" id="graph" data-percent="88"></div>
Javascript
var el = document.getElementById('graph'); // get canvas
var options = {
percent: el.getAttribute('data-percent') || 25,
size: el.getAttribute('data-size') || 220,
lineWidth: el.getAttribute('data-line') || 15,
rotate: el.getAttribute('data-rotate') || 0
}
var canvas = document.createElement('canvas');
var span = document.createElement('span');
span.textContent = options.percent + '%';
if (typeof(G_vmlCanvasManager) !== 'undefined') {
G_vmlCanvasManager.initElement(canvas);
}
var ctx = canvas.getContext('2d');
canvas.width = canvas.height = options.size;
el.appendChild(span);
el.appendChild(canvas);
ctx.translate(options.size / 2, options.size / 2); // change center
ctx.rotate((-1 / 2 + options.rotate / 180) * Math.PI); // rotate -90 deg
//imd = ctx.getImageData(0, 0, 240, 240);
var radius = (options.size - options.lineWidth) / 2;
var drawCircle = function(color, lineWidth, percent) {
percent = Math.min(Math.max(0, percent || 1), 1);
ctx.beginPath();
ctx.arc(0, 0, radius, 0, Math.PI * 2 * percent, false);
ctx.strokeStyle = color;
ctx.lineCap = 'round'; // butt, round or square
ctx.lineWidth = lineWidth
ctx.stroke();
};
drawCircle('#efefef', options.lineWidth, 100 / 100);
drawCircle('#555555', options.lineWidth, options.percent / 100);
and CSS
div {
position:relative;
margin:80px;
width:220px; height:220px;
}
canvas {
display: block;
position:absolute;
top:0;

Basic code was taken from Simple PIE Chart http://rendro.github.io/easy-pie-chart/
Check this out :)
I made this one using conic-gradient.
background: conic-gradient(
SomeColor1 80%,
SomeColor2 80%
);
You can create a pie chart using conic-gradient.
div {
background: conic-gradient(
red 36deg, orange 36deg 170deg, yellow 170deg);
border-radius: 50%
}
I select only two colors for the pie chart.
background: conic-gradient(
rgb(3, 133, 255) 80%,
rgb(242, 242, 242) 80%
);
then place a div on top of the pie chart to make it looks like a circular progress indicator. Then set progress using HTML DOM innerHTML option.
Then you can use incrementProgress() and decrementProgress() fuctions to change progress dynamically.
Follow my complete example to get some idea :)
You can make upload/download progress indicators, charts for dashboards, etc. using this.

Another pure css based solution that is based on two clipped rounded elements that i rotate to get to the right angle:
http://jsfiddle.net/maayan/byT76/
That's the basic css that enables it:
.clip1 {
position:absolute;
top:0;left:0;
width:200px;
height:200px;
clip:rect(0px,200px,200px,100px);
}
.slice1 {
position:absolute;
width:200px;
height:200px;
clip:rect(0px,100px,200px,0px);
-moz-border-radius:100px;
-webkit-border-radius:100px;
border-radius:100px;
background-color:#f7e5e1;
border-color:#f7e5e1;
-moz-transform:rotate(0);
-webkit-transform:rotate(0);
-o-transform:rotate(0);
transform:rotate(0);
}
.clip2
{
position:absolute;
top:0;left:0;
width:200px;
height:200px;
clip:rect(0,100px,200px,0px);
}
.slice2
{
position:absolute;
width:200px;
height:200px;
clip:rect(0px,200px,200px,100px);
-moz-border-radius:100px;
-webkit-border-radius:100px;
border-radius:100px;
background-color:#f7e5e1;
border-color:#f7e5e1;
-moz-transform:rotate(0);
-webkit-transform:rotate(0);
-o-transform:rotate(0);
transform:rotate(0);
}
and the js rotates it as required.
quite easy to understand..
Hope it helps,

A minimalistic approach using just one element and a couple of attributes:
Use data-progress to define the internal label and --progress to define the progress from 0deg to 360deg.
<div data-progress="36" style="--progress: 36deg;">36%</div>
div {
display: flex;
width: 100px;
height: 100px;
border-radius: 50%;
background: conic-gradient(red var(--progress), gray 0deg);
font-size: 0;
}
div::after {
content: attr(data-progress) '%';
display: flex;
justify-content: center;
flex-direction: column;
width: 100%;
margin: 10px;
border-radius: 50%;
background: white;
font-size: 1rem;
text-align: center;
}
<div data-progress="36" style="--progress: 36deg;">36%</div>
Here's a naïve approach to the animation, again all CSS, no JS and just one element:
div {
display: flex;
width: 100px;
height: 100px;
border-radius: 50%;
background: conic-gradient(red var(--progress), gray 0deg);
font-size: 0;
animation: .4s ease-out turn_in reverse;
}
div::after {
content: attr(data-progress);
display: flex;
justify-content: center;
flex-direction: column;
width: 100%;
margin: 10px;
border-radius: 50%;
background: white;
font-size: 1rem;
text-align: center;
}
#keyframes turn_in {
5% {
background: conic-gradient(red calc(var(--progress) * .95), gray 0deg);
}
10% {
background: conic-gradient(red calc(var(--progress) * .9), gray 0deg);
}
15% {
background: conic-gradient(red calc(var(--progress) * .85), gray 0deg);
}
20% {
background: conic-gradient(red calc(var(--progress) * .8), gray 0deg);
}
25% {
background: conic-gradient(red calc(var(--progress) * .75), gray 0deg);
}
30% {
background: conic-gradient(red calc(var(--progress) * .7), gray 0deg);
}
35% {
background: conic-gradient(red calc(var(--progress) * .65), gray 0deg);
}
40% {
background: conic-gradient(red calc(var(--progress) * .6), gray 0deg);
}
45% {
background: conic-gradient(red calc(var(--progress) * .55), gray 0deg);
}
50% {
background: conic-gradient(red calc(var(--progress) * .5), gray 0deg);
}
55% {
background: conic-gradient(red calc(var(--progress) * .45), gray 0deg);
}
60% {
background: conic-gradient(red calc(var(--progress) * .4), gray 0deg);
}
65% {
background: conic-gradient(red calc(var(--progress) * .35), gray 0deg);
}
70% {
background: conic-gradient(red calc(var(--progress) * 0.3), gray 0deg);
}
75% {
background: conic-gradient(red calc(var(--progress) * 0.25), gray 0deg);
}
80% {
background: conic-gradient(red calc(var(--progress) * .2), gray 0deg);
}
85% {
background: conic-gradient(red calc(var(--progress) * .15), gray 0deg);
}
90% {
background: conic-gradient(red calc(var(--progress) * .1), gray 0deg);
}
95% {
background: conic-gradient(red calc(var(--progress) * .05), gray 0deg);
}
100% {
background: conic-gradient(gray 0deg);
}
}
<div data-progress="85%" style="--progress: 85%;">85%</div>
Disclaimer: cross-browsing not tested.
A different idea with new #property. See the support table
#property --a {
syntax: '<angle>';
inherits: false;
initial-value: 90deg;
}
.circle {
width: 120px;
height: 120px;
padding: 12px;
box-sizing: border-box;
-webkit-mask:
conic-gradient(#000 var(--a), transparent var(--a)),
linear-gradient(#000, #000) content-box;
-webkit-mask-composite: source-out;
mask-composite: subtract;
background: tomato;
border-radius: 50%;
animation: progress 1s .3s linear forwards;
}
#keyframes progress {
to {
--a: 250deg;
}
}
<div class="circle"></div>
And I saw a more powerful example by Alvaro Montoro. Be sure to check this out.
acceding your data you can change process like <div ... data-num="50"> output 50% that go to the show fully animated circles and number.
change in data-num="/* 0-100 */".
you can add multiple process like 5,10.
using Javascript,CSS,Html with animated circle and number.
Output
Code
let items = document.querySelectorAll('.progress-item');
const counters = Array(items.length);
const intervals = Array(items.length);
counters.fill(0);
items.forEach((number,index) => {
intervals[index] = setInterval(() => {
if(counters[index] == parseInt(number.dataset.num)){
clearInterval(intervals[index]);
}else{
counters[index] += 1;
number.style.background = "conic-gradient(red calc(" + counters[index] + "%), gray 0deg)";
number.setAttribute('data-value', counters[index] + "%");
number.innerHTML = counters[index] + "%";
}

I made a circular div with class .seg and used linear-gradient to make the circular segments. Then I rotated these segments to create aperture but the last segment is the hurdle.
I then tried to used conic-gradient to cut off the corners of the segments on the left but this just forms an Octagon in the middle :(

I make the 8 triangles as child one of other, so we don't need to apply a specific rotation and position to each one, as each is relative to it's parent.
I also use :before pseudo element inside each <i>, so we don't need more elements on the html code and we can add extra transformation to the triangles without deform the logo.
The size is relative to the #logo's font-size value, so change it and all is relative.
I also put a closing animation when you hover it with the mouse.
I don't need to hide pieces with other elements, so we can place it over anything and just works. (like the gradient that i put on this example.)

I don't know if this helps, but I would recommend using an <svg> to do the task.
I have a circle progress bar, only with HTML and CSS, I used keyframes for loading (animation). But the loading is from right to left I wanna reverse it. I edit my CSS keyframes but nothing at all. I try also animation reverse again nothing.

By the way here is another idea that rely on less code. The trick is to consider clip-path where you will adjust the position of the different points in order to create the needed animation
.box {
width:150px;
height:150px;
margin:20px;
box-sizing:border-box;
font-size:30px;
display:flex;
align-items:center;
justify-content:center;
position:relative;
z-index:0;
}
.box:before {
content:"";
position:absolute;
z-index:-1;
top:0;
left:0;
right:0;
bottom:0;
border:5px solid #000;
border-radius:50%;
transform:rotate(45deg);
clip-path:polygon(50% 50%,0 0,0 0,0 0, 0 0,0 0);
animation:change 2s linear forwards;
}
#keyframes change {
25% {
clip-path:polygon(50% 50%,0 0, 0 100%,0 100%,0 100%,0 100%);
}
50% {
clip-path:polygon(50% 50%,0 0,0 100%, 100% 100%, 100% 100%,100% 100%);
}
75% {
clip-path:polygon(50% 50%,0 0,0 100%,100% 100%, 100% 0,100% 0);
}
100% {
clip-path:polygon(50% 50%,0 0,0 100%,100% 100%, 100% 0, 0% 0%);
}
}
body {
background:pink;
}
<div class="box">

To better understand the animation, add background and remove the radius. We basically have 6 points in the polygon where 2 are fixed (the center (50% 50%) and top one (0 0)) then we move the 4 others to put them in the corners. The trick is to move them together and we leave one at each corner (each state of the animation).
.box {
width:100px;
height:100px;
margin:50px;
box-sizing:border-box;
font-size:30px;
display:flex;
align-items:center;
justify-content:center;
position:relative;
z-index:0;
background:rgba(0,0,0,0.5);
}
.box:before {

z-index:-1;

bottom:0;
border:5px solid #000;
background:red;
transform:rotate(45deg);
clip-path:polygon(50% 50%,0 0,0 0,0 0, 0 0,0 0);
animation:change 5s linear forwards;
}
#keyframes change {
25% {
clip-path:polygon(50% 50%,0 0, 0 100%,0 100%,0 100%,0 100%);
}
50% {
clip-path:polygon(50% 50%,0 0,0 100%, 100% 100%, 100% 100%,100% 100%);
}
75% {
clip-path:polygon(50% 50%,0 0,0 100%,100% 100%, 100% 0,100% 0);
}
100% {
clip-path:polygon(50% 50%,0 0,0 100%,100% 100%, 100% 0, 0% 0%);
}
}
body {

}
<div class="box">

With this code you have the full animation, simply adjust the final state or remove some states to stop it where you want.
Ex with 75% (we remove the last state)
.box {
width:150px;
height:150px;
margin:20px;
box-sizing:border-box;
font-size:30px;
display:flex;
align-items:center;
justify-content:center;
position:relative;
z-index:0;
}
.box:before {
content:"";
position:absolute;
z-index:-1;
top:0;
left:0;
right:0;
bottom:0;
border:5px solid #000;
border-radius:50%;
transform:rotate(45deg);
clip-path:polygon(50% 50%,0 0,0 0,0 0, 0 0,0 0);
animation:change 3s linear forwards;
}
#keyframes change {
33% {
clip-path:polygon(50% 50%,0 0, 0 100%,0 100%,0 100%,0 100%);
}
66% {
clip-path:polygon(50% 50%,0 0,0 100%, 100% 100%, 100% 100%,100% 100%);
}
100% {
clip-path:polygon(50% 50%,0 0,0 100%,100% 100%, 100% 0,100% 0);
}
}
body {
background:pink;
}
<div class="box">
75%
</div>
With 66% (we remove the last state and we change the percentage of the third one)
.box {
width:150px;
height:150px;
margin:20px;
box-sizing:border-box;
font-size:30px;
display:flex;

}
.box:before {

z-index:-1;
top:0;
left:0;
right:0;
bottom:0;
border:5px solid #000;
border-radius:50%;
transform:rotate(45deg);
clip-path:polygon(50% 50%,0 0,0 0,0 0, 0 0,0 0);
animation:change 2s linear forwards;
}
#keyframes change {
33% {
clip-path:polygon(50% 50%,0 0, 0 100%,0 100%,0 100%,0 100%);
}
66% {
clip-path:polygon(50% 50%,0 0,0 100%, 100% 100%, 100% 100%,100% 100%);
}
100% {
clip-path:polygon(50% 50%,0 0,0 100%,100% 100%, 100% 0,100% 40%);
}
}
<div class="box">
75%
</div>
with 10% (only one state)
.box {
width:150px;
height:150px;
margin:20px;
box-sizing:border-box;
font-size:30px;
display:flex;

This progress works in new blink/webkit browsers since it uses conic-gradient(). In addition, to change the progress we use css variables, so animation will require JS.
The idea is to create a conic gradient of black to transparent, and change the degrees according to the progress. To get a line instead of a circle, I use an inner gradient from white to white, that doesn't cover the border (background-clip: content-box) as suggested by #TemaniAfif.
Play with the values of the input box to see the progress.
const progress = document.querySelector('.circular-progress')
const updateProgress = value => {
progress.style.setProperty('--percentage', `${value * 3.6}deg`)
progress.innerText = `${value}%`
}
updateProgress(36)
document.querySelector('input')
.addEventListener('input', e => {
updateProgress(e.currentTarget.value)
})
.circular-progress {
display: flex;
width: 150px;
height: 150px;
border:5px solid transparent;
border-radius: 50%;
align-items: center;
justify-content: center;
font-size: 1.5em;
background:
linear-gradient(#fff, #fff) content-box no-repeat,
conic-gradient(black var(--percentage,0), transparent var(--percentage,0)) border-box;
--percentage: 0deg;
}
<div class="circular-progress"></div>
<br />
Progress value: <input type="number" min="0" max="100" value="36">
And for the other direction (added by #TemaniAfif):
const progress = document.querySelector('.circular-progress')
const updateProgress = value => {
progress.style.setProperty('--percentage', `${value * 3.6}deg`)
progress.innerText = `${value}%`
}
updateProgress(36)
document.querySelector('input')
.addEventListener('input', e => {
updateProgress(e.currentTarget.value)
})
.circular-progress {
display: flex;
width: 150px;
height: 150px;
border:5px solid transparent;
border-radius: 50%;
align-items: center;
justify-content: center;
font-size: 1.5em;
background:
linear-gradient(#fff, #fff) content-box no-repeat,
conic-gradient(from calc(-1*var(--percentage)), black var(--percentage,0), transparent var(--percentage,0)) border-box;
--percentage: 0deg;
}
<div class="circular-progress"></div>
<br />
Progress value: <input type="number" min="0" max="100" value="36">
A variation on the same idea, is to create progress circle with multiple colors, and then hide it using a gradient from transparent to white. Make the transparent area bigger to expose the colored line.
const progress = document.querySelector('.circular-progress')
const updateProgress = value => {
progress.style.setProperty('--percentage', `${value * 3.6}deg`)
progress.innerText = `${value}%`
}
updateProgress(80)
document.querySelector('input')
.addEventListener('input', e => {
updateProgress(e.currentTarget.value)
})
.circular-progress {
display: flex;
width: 150px;
height: 150px;
border: 5px solid transparent;
border-radius: 50%;
align-items: center;
justify-content: center;
font-size: 1.5em;
background:
linear-gradient(#fff, #fff) content-box no-repeat,
conic-gradient(transparent var(--percentage, 0), white var(--percentage, 0)) border-box,
conic-gradient(green 120deg, yellow 120deg 240deg, red 240deg) border-box;
--percentage: 0deg;
}
<div class="circular-progress"></div>
<br /> Progress value: <input type="number" min="0" max="100" value="80">
I want to have a straight line in my header, and then a few seconds after the page loads, I want those lines to slowly move down until they look like the one in the image below:
I thought of using css transform property to rotate two rotate two divs, but that does not seem to be a solution as you can see the result in my pen here
HTML:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
<div id="big">
<div class="arrow-box">
<div class="line line-1"></div>
<div class="line line-2"></div>
</div>
</div>
CSS:
#big{
background: red;
height: 200px;
}
.arrow-box{
max-width: 200px;
margin: 0 auto;
padding-top: 10px;
}
.line{
background: white;
width: 60px;
height: 1px;
}
.line-1{
transform: rotate(20deg);
}
.line-2{
transform: rotate(-20deg);
}
How can I make a/the line look like the icon on the image after the page loads?
You could do this using css animation. You could use rotateZ transform to create arrow shape and also scale to keep increasing width of the lines as animation goes.
You also need to use transform-origin for both parts to transform at the right point.
.line {
position: relative;
width: 100px;
}
.line:after,
.line:before {
background: black;
position: absolute;
content: "";
height: 2px;
width: 50%;
bottom: 0;
}
.line:before {
left: 0;
animation: moveBefore 1s linear forwards;
transform-origin: center left;
}
.line:after {
right: 0;
animation: moveAfter 1s linear forwards;
transform-origin: center right;
}
#keyframes moveBefore {
0% {
transform: rotateZ(0) scale(1, 1);
}
50% {
transform: rotateZ(15deg) scale(1.05, 1);
}
100% {
transform: rotateZ(30deg) scale(1.16, 1);
}
}
#keyframes moveAfter {
0% {
transform: rotateZ(0) scale(1, 1);
}
50% {
transform: rotateZ(-15deg) scale(1.05, 1);
}
100% {
transform: rotateZ(-30deg) scale(1.16, 1);
}
}
<div class="line"></div>
You could also do this with svg using line element and some javascript to move y position left and right line parts. To increase angle gradually you can use setInterval method.
let step = 0;
const left = document.querySelector('.left-line');
const right = document.querySelector('.right-line');
function move(el, prop, size) {
el.setAttribute(prop, +el.getAttribute(prop) + size);
}
setInterval(() => {
if (step <= 40) {
move(left, 'y2', 0.8);
move(right, 'y1', 0.8)
step += 1;

While the accepted answer works just fine the artist in me can't take the overlapping of the lines in the center due to the scaling. Here's a few alternate options:
Option 1 - clip-path
Using clip-path, animate the mid-points of a rectangle to transform the polygon into a chevron. This works by masking the background color of the element outside of the animated shape.
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.line {
display: inline-block;
width: 200px;
height: 50px;
background-color: black;
clip-path: polygon(0 0, 100% 0, 100% 2px, 0 2px);
animation: 2s infinite linear;
}
.line.down {
animation-name: chevron-down;
}
.line.up {
animation-name: chevron-up;
}
#keyframes chevron-down {
from {
clip-path: polygon(0 0, 50% 0, 100% 0, 100% 2px, 50% 2px, 0 2px);
}
to {
clip-path: polygon(0 0, 50% 48px, 100% 0, 100% 2px, 50% 50px, 0 2px);
}
}
#keyframes chevron-up {
from {
clip-path: polygon(0 48px, 50% 48px, 100% 48px, 100% 50px, 50% 50px, 0 50px);
}
to {
clip-path: polygon(0 0, 50% 48px, 100% 0, 100% 2px, 50% 50px, 0 2px);
}
}
<div class="line down"></div>
<div class="line up"></div>
Support for clip-path is spotty, however.
Option 2 - pseudo-elements
If you can't use clip-path or prefer to use pseudo elements, change their placement and origins of transform to come from the center (and not the upper corners):
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.line {
position: relative;
width: 200px;
height: 50px;
overflow: hidden;
}
.line::before,
.line::after {
position: absolute;
content: '';
display: block;
bottom: 0;
height: 2px;
width: 50%;
background-color: black;
animation: 2s linear infinite;
}
.line::before {
transform-origin: bottom right;
left: 0;
animation-name: before;
}
.line::after {
transform-origin: bottom left;
right: 0;
animation-name: after;
}
#keyframes before {
to { transform: rotateZ(30deg); }
}
#keyframes after {
to { transform: rotateZ(-30deg); }
}
<div class="line"></div>
I have searched this website to find progress bars, but the ones I have been able to found show animated circles that go to the full 100%.
I would like it to stop at certain percentages like in the screenshot below. Is there any way I can do that using only CSS?
I created a fiddle using only CSS.
.wrapper {
width: 100px; /* Set the size of the progress bar */
height: 100px;
position: absolute; /* Enable clipping */
clip: rect(0px, 100px, 100px, 50px); /* Hide half of the progress bar */
}
/* Set the sizes of the elements that make up the progress bar */
.circle {
width: 80px;
height: 80px;
border: 10px solid green;
border-radius: 50px;
position: absolute;
clip: rect(0px, 50px, 100px, 0px);
}
/* Using the data attributes for the animation selectors. */
/* Base settings for all animated elements */
div[data-anim~=base] {
-webkit-animation-iteration-count: 1; /* Only run once */
-webkit-animation-fill-mode: forwards; /* Hold the last keyframe */
-webkit-animation-timing-function:linear; /* Linear animation */
}
.wrapper[data-anim~=wrapper] {
-webkit-animation-duration: 0.01s; /* Complete keyframes asap */
-webkit-animation-delay: 3s; /* Wait half of the animation */
-webkit-animation-name: close-wrapper; /* Keyframes name */
}
.circle[data-anim~=left] {
-webkit-animation-duration: 6s; /* Full animation time */
-webkit-animation-name: left-spin;
}
.circle[data-anim~=right] {
-webkit-animation-duration: 3s; /* Half animation time */
-webkit-animation-name: right-spin;
}
/* Rotate the right side of the progress bar from 0 to 180 degrees */
#-webkit-keyframes right-spin {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(180deg);
}
}
/* Rotate the left side of the progress bar from 0 to 360 degrees */
#-webkit-keyframes left-spin {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(360deg);
}
}
/* Set the wrapper clip to auto, effectively removing the clip */
#-webkit-keyframes close-wrapper {
to {
clip: rect(auto, auto, auto, auto);
}
}
<div class="wrapper" data-anim="base wrapper">

Or this beautiful round progress bar with HTML5, CSS3 and JavaScript.
What about that?
HTML
<div class="chart" id="graph" data-percent="88"></div>
Javascript
var el = document.getElementById('graph'); // get canvas
var options = {
percent: el.getAttribute('data-percent') || 25,

lineWidth: el.getAttribute('data-line') || 15,
rotate: el.getAttribute('data-rotate') || 0
}
var canvas = document.createElement('canvas');
var span = document.createElement('span');
span.textContent = options.percent + '%';
if (typeof(G_vmlCanvasManager) !== 'undefined') {
G_vmlCanvasManager.initElement(canvas);
}
var ctx = canvas.getContext('2d');
canvas.width = canvas.height = options.size;
el.appendChild(span);
el.appendChild(canvas);
ctx.translate(options.size / 2, options.size / 2); // change center
ctx.rotate((-1 / 2 + options.rotate / 180) * Math.PI); // rotate -90 deg
//imd = ctx.getImageData(0, 0, 240, 240);
var radius = (options.size - options.lineWidth) / 2;
var drawCircle = function(color, lineWidth, percent) {
percent = Math.min(Math.max(0, percent || 1), 1);
ctx.beginPath();
ctx.arc(0, 0, radius, 0, Math.PI * 2 * percent, false);
ctx.strokeStyle = color;
ctx.lineCap = 'round'; // butt, round or square
ctx.lineWidth = lineWidth
ctx.stroke();
};
drawCircle('#efefef', options.lineWidth, 100 / 100);
drawCircle('#555555', options.lineWidth, options.percent / 100);

Basic code was taken from Simple PIE Chart http://rendro.github.io/easy-pie-chart/
Check this out :)
I made this one using conic-gradient.
background: conic-gradient(
SomeColor1 80%,
SomeColor2 80%
);
You can create a pie chart using conic-gradient.
div {
background: conic-gradient(
red 36deg, orange 36deg 170deg, yellow 170deg);
border-radius: 50%
}
I select only two colors for the pie chart.
background: conic-gradient(
rgb(3, 133, 255) 80%,
rgb(242, 242, 242) 80%
);
then place a div on top of the pie chart to make it looks like a circular progress indicator. Then set progress using HTML DOM innerHTML option.
Then you can use incrementProgress() and decrementProgress() fuctions to change progress dynamically.
Follow my complete example to get some idea :)
You can make upload/download progress indicators, charts for dashboards, etc. using this.

Another pure css based solution that is based on two clipped rounded elements that i rotate to get to the right angle:
http://jsfiddle.net/maayan/byT76/
That's the basic css that enables it:
.clip1 {
position:absolute;
top:0;left:0;
width:200px;
height:200px;
clip:rect(0px,200px,200px,100px);
}
.slice1 {
position:absolute;
width:200px;
height:200px;
clip:rect(0px,100px,200px,0px);
-moz-border-radius:100px;
-webkit-border-radius:100px;
border-radius:100px;
background-color:#f7e5e1;
border-color:#f7e5e1;
-moz-transform:rotate(0);
-webkit-transform:rotate(0);
-o-transform:rotate(0);
transform:rotate(0);
}
.clip2
{
position:absolute;
top:0;left:0;
width:200px;
height:200px;
clip:rect(0,100px,200px,0px);
}
.slice2
{
position:absolute;
width:200px;
height:200px;
clip:rect(0px,200px,200px,100px);
-moz-border-radius:100px;
-webkit-border-radius:100px;
border-radius:100px;
background-color:#f7e5e1;
border-color:#f7e5e1;
-moz-transform:rotate(0);
-webkit-transform:rotate(0);
-o-transform:rotate(0);
transform:rotate(0);
}
and the js rotates it as required.
quite easy to understand..
Hope it helps,
Maayan
A minimalistic approach using just one element and a couple of attributes:
Use data-progress to define the internal label and --progress to define the progress from 0deg to 360deg.
<div data-progress="36" style="--progress: 36deg;">36%</div>
div {
display: flex;
width: 100px;
height: 100px;
border-radius: 50%;
background: conic-gradient(red var(--progress), gray 0deg);
font-size: 0;
}
div::after {
content: attr(data-progress) '%';
display: flex;
justify-content: center;
flex-direction: column;
width: 100%;
margin: 10px;
border-radius: 50%;
background: white;
font-size: 1rem;
text-align: center;
}
<div data-progress="36" style="--progress: 36deg;">36%</div>
Here's a naïve approach to the animation, again all CSS, no JS and just one element:
div {
display: flex;
width: 100px;
height: 100px;
border-radius: 50%;
background: conic-gradient(red var(--progress), gray 0deg);
font-size: 0;
animation: .4s ease-out turn_in reverse;
}
div::after {
content: attr(data-progress);
display: flex;
justify-content: center;
flex-direction: column;
width: 100%;
margin: 10px;
border-radius: 50%;
background: white;
font-size: 1rem;
text-align: center;
}
#keyframes turn_in {
5% {
background: conic-gradient(red calc(var(--progress) * .95), gray 0deg);
}
10% {
background: conic-gradient(red calc(var(--progress) * .9), gray 0deg);
}
15% {
background: conic-gradient(red calc(var(--progress) * .85), gray 0deg);
}
20% {
background: conic-gradient(red calc(var(--progress) * .8), gray 0deg);
}
25% {
background: conic-gradient(red calc(var(--progress) * .75), gray 0deg);
}
30% {
background: conic-gradient(red calc(var(--progress) * .7), gray 0deg);
}
35% {
background: conic-gradient(red calc(var(--progress) * .65), gray 0deg);
}
40% {
background: conic-gradient(red calc(var(--progress) * .6), gray 0deg);
}
45% {
background: conic-gradient(red calc(var(--progress) * .55), gray 0deg);
}
50% {
background: conic-gradient(red calc(var(--progress) * .5), gray 0deg);
}
55% {
background: conic-gradient(red calc(var(--progress) * .45), gray 0deg);
}
60% {
background: conic-gradient(red calc(var(--progress) * .4), gray 0deg);
}
65% {
background: conic-gradient(red calc(var(--progress) * .35), gray 0deg);
}
70% {
background: conic-gradient(red calc(var(--progress) * 0.3), gray 0deg);
}
75% {
background: conic-gradient(red calc(var(--progress) * 0.25), gray 0deg);
}
80% {
background: conic-gradient(red calc(var(--progress) * .2), gray 0deg);
}
85% {
background: conic-gradient(red calc(var(--progress) * .15), gray 0deg);
}
90% {
background: conic-gradient(red calc(var(--progress) * .1), gray 0deg);
}
95% {
background: conic-gradient(red calc(var(--progress) * .05), gray 0deg);
}
100% {
background: conic-gradient(gray 0deg);
}
}
<div data-progress="85%" style="--progress: 85%;">85%</div>

And I saw a more powerful example by Alvaro Montoro. Be sure to check this out.
acceding your data you can change process like <div ... data-num="50"> output 50% that go to the show fully animated circles and number.
change in data-num="/* 0-100 */".
you can add multiple process like 5,10.
using Javascript,CSS,Html with animated circle and number.
Output
Code
let items = document.querySelectorAll('.progress-item');
const counters = Array(items.length);
const intervals = Array(items.length);
counters.fill(0);
items.forEach((number,index) => {
intervals[index] = setInterval(() => {
if(counters[index] == parseInt(number.dataset.num)){
clearInterval(intervals[index]);
}else{
counters[index] += 1;
number.style.background = "conic-gradient(red calc(" + counters[index] + "%), gray 0deg)";
number.setAttribute('data-value', counters[index] + "%");
number.innerHTML = counters[index] + "%";
}

I have a disc whose size can change, and some icons arranged around that disc. The icons should always be on the border of the disc, and the intervals between each icon should always stay the same.
Can this be done in pure css without having to compute each icon's position whenever the disc grows or shrinks?
Expected result:
.container:nth-child(1)
{
position: absolute;
top: 20px;
left: 30px;
height: 280px;
width: 280px;

Without a preprocessor, I believe you'll need a script to achieve this. Here I've used jQuery in order to compute the intervals on hover.
Note
this would also support a dynamic number of .circle elements
+ function() {
var to;
$(".wrap").on('mouseenter', function() {
var circles = $(this).find(".circle");
var degree = (2 * Math.PI) / circles.length; //calc delta angle
var transforms = [];
// Calculate the position for each circle
circles.each(function(index) {
var x = 100 * Math.cos(-0.5 * Math.PI + degree * (-1 * index - 0.5));
var y = 100 * Math.sin(-0.5 * Math.PI + degree * (-1 * index - 0.5));
transforms.push('translate(' + x + 'px,' + y + 'px)');
});
// Function to moves all the circles
// We'll pop a circle each time and than call this function recursively
function moveCircles() {
var transform = transforms.shift();
circles.css('transform', transform);
circles.splice(0, 1);
if (circles.length) to = setTimeout(moveCircles, 400);
}
moveCircles();
});
$(".wrap").on('mouseleave', function() {
var circles = $(this).children().css('transform', '');
clearTimeout(to);
});
}();

There is a way to do it programmatically, but only with CSS3. What you have to do is have an element inside it that takes the full width and can rotate, and then counterrotate the inner containers of those rotating elements.
So you would have to define the circles by using :nth-child. In order to achieve the correct effect and not apply a style twice, we will have to count down from our last element in order to only attract elements at a certain position. This is because :nth-child(2n) applies to :nth-child(4n) as well, which might create overlapping styles. Skip to the snippet if this seems a bit too complicated - it's actually quite simple.
So your basic HTML would be:
<wrapper> <!-- This is your disc -->
<rotation> <!-- A rotation element. -->
<counter> <!-- A counter-rotation element. This contains your content. -->
The first element has to have a position enabled. The second element needs to overlap with all the other secondary elements, so it needs a position of absolute, and the third element, well, that's up to you. It's just there to counter rotate it again.
Heres an implementation:
/*The following animation shows that the outer frame is resizeable.*/
#-webkit-keyframes sizeBounce { 0% {width: 50vw; height: 50vw; } 50% {width: 20vw; height: 20vw; } 100% {width: 50vw; height: 50vw; }}
#keyframes sizeBounce { 0% {width: 50vw; height: 50vw; } 50% {width: 20vw; height: 20vw; } 100% {width: 50vw; height: 50vw; }}
div {
position: relative;
/* Any height you want here */
width: 20vw;
height: 20vw;
border-radius: 50%;
border: 1px solid #000;
-webkit-animation: sizeBounce 2s infinite;
animation: sizeBounce 2s infinite;
/* You can do anything you want with this circle! */
position: absolute;
top: 50%;
left: 50%;
-webkit-transform: translate(-50%,-50%);
transform: translate(-50%,-50%);
}
div > span {
position: absolute;
display: block;
width: 100%;
height: 100%;
top: 0;
left: 0;
transform: rotateZ(0deg);
transform-origin: 50% 50%;
}
div > span > em {
display: block;
position: absolute;
left: 0;
top: 0;
width: 20%;
height: 20%;
border-radius: 50%;
border: 1px solid #dd0300;
text-align: center;
}
div > span:nth-child(6n-6) {
-webkit-transform: rotateZ(0deg);
transform: rotateZ(0deg);
}
div > span:nth-child(6n-6) > em {
-webkit-transform: rotateZ(0deg);
transform: rotateZ(0deg);
}
div > span:nth-child(6n-4) {
-webkit-transform: rotateZ(60deg);
transform: rotateZ(60deg);
}
div > span:nth-child(6n-4) > em {
-webkit-transform: rotateZ(-60deg);
transform: rotateZ(-60deg);
}
div > span:nth-child(6n-3) {
-webkit-transform: rotateZ(120deg);
transform: rotateZ(120deg);
}
div > span:nth-child(6n-3) > em {
-webkit-transform: rotateZ(-120deg);
transform: rotateZ(-120deg);
}
div > span:nth-child(6n-2) {
-webkit-transform: rotateZ(180deg);
transform: rotateZ(180deg);
}
div > span:nth-child(6n-2) > em {
-webkit-transform: rotateZ(-180deg);
transform: rotateZ(-180deg);
}
div > span:nth-child(6n-1) {
-webkit-transform: rotateZ(240deg);
transform: rotateZ(240deg);
}
div > span:nth-child(6n-1) > em {
-webkit-transform: rotateZ(-240deg);
transform: rotateZ(-240deg);
}
div > span:nth-child(6n) {
-webkit-transform: rotateZ(300deg);
transform: rotateZ(300deg);
}
div > span:nth-child(6n) > em {
-webkit-transform: rotateZ(-300deg);
transform: rotateZ(-300deg);
}
<div>
<span><em>1</em></span>
<span><em>2</em></span>
<span><em>3</em></span>
<span><em>4</em></span>
<span><em>5</em></span>
<span><em>6</em></span>
</div>
There is a way to automate this is SASS as well and it looks something like this:
#mixin rotatePiecemeally($pieces:6,$wrapper:span,$container:em){
/* First calculate the angle between each piece */
$degrees : 360 / $pieces;
/* We want to count back from the amount of pieces to 0
* The counting is because simple counting 2n, 3n, 4n, ...
* will result in 4n inheriting from 2n - to keep things clean,
* we want to avoid that. */
#for $i from 0 through ($pieces - 1){
& #{$wrapper}:nth-child(#{$pieces}n-#{$i}){
transform: rotateZ(#{$i * $degrees}deg);
}
& #{$wrapper}:nth-child(#{$pieces}n-#{$i}) > #{$container}{
transform: rotateZ(#{-$i * $degrees}deg);
}
}
}
You can call it by doing the following:
#mycircle {
#include rotatePiecemeally(6);
}
And you can optionally include which elements you want to use as the children. Don't forget they all need some absolute positioning for this to work. Don't forget to add any prefixes you need (I added them to the snippet because I am using Safari)
