CSS3 simple donut chart

Question

What I'm trying to do is create a simple donut chart. I'm currently using CSS(3) only but I don't know if it's possible without javascript.

What I have so far: http://jsfiddle.net/aBP5Q/

HTML:

<div class="donut-container" style="background: #9C0;">
    <div class="donut-inner">
        <div class="donut-label">HTML</div>
    </div>
</div>

CSS:

.donut-container {
    width: 150px;
    height: 150px;
    float: left;
    -webkit-border-radius: 75px;
    -moz-border-radius: 75px;
    border-radius: 75px;
    margin-right: 20px;
}

.donut-inner {
    width: 134px;
    height: 134px;
    position: relative;
    top: 8px;
    left: 8px;
    background: #FFF;
    -webkit-border-radius: 65px;
    -moz-border-radius: 65px;
    border-radius: 65px;
}

.donut-label {
    line-height: 130px;
    text-align: center;
    font-size: 20px;
}

I would like to display the green and blue colors as the precentage. So no green is 0% and full green (360 degrees) is 100%. Maybe even with a simple animation when the chart is loaded if its possible.

Your help is much appreciated.

Answer 1

SVG for the win!

.item {
    position: relative;
    float: left;
}

.item h2 {
    text-align:center;
    position: absolute;
    line-height: 125px;
    width: 100%;
}

svg {
   -webkit-transform: rotate(-90deg);
    transform: rotate(-90deg);
}

.circle_animation {
  stroke-dasharray: 440; /* this value is the pixel circumference of the circle */
  stroke-dashoffset: 440;
}

.html .circle_animation {
    -webkit-animation: html 1s ease-out forwards;
    animation: html 1s ease-out forwards;
}

.css .circle_animation {
    -webkit-animation: css 1s ease-out forwards;
    animation: css 1s ease-out forwards;
}

@-webkit-keyframes html {
  to {
    stroke-dashoffset: 80; /* 50% would be 220 (half the initial value specified above) */
  }
}

@keyframes html {
  to {
    stroke-dashoffset: 80;
  }
}

@-webkit-keyframes css {
  to {
    stroke-dashoffset: 160;
  }
}

@keyframes css {
  to {
    stroke-dashoffset: 160;
  }
}

<div class="item html">
    <h2>HTML</h2>
    <svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">
     <g>

      <circle class="circle_animation" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#6fdb6f" fill="none"/>
     </g>
    </svg>
</div>

<div class="item css">

Here is a version with background circles as requested in the comments:

    transform: rotate(-90deg);
}

.circle_animation {
  stroke-dasharray: 440; /* this value is the pixel circumference of the circle */
  stroke-dashoffset: 440;
}

.html .circle_animation {
    -webkit-animation: html 1s ease-out forwards;
    animation: html 1s ease-out forwards;
}

.css .circle_animation {

How does it work?

stroke-dasharray is used to define the 'pattern' a dashed line uses (MDN). By providing a single value you create a pattern with a dash of 440px and a space of 440px. (440px is roughly the circumference of the circle).

stroke-dashoffset effectively moves the starting point of the dash pattern (MDN).

A dash-offset of 220 (half of the stroke-dasharray) would produce a half-circle. 110 = quarter circle etc.

Answer 2

i wrote this as a comment reply but it was too long :

hm... well, here is a fiddle for the second circle http://jsfiddle.net/LgtV2/ .... it has 3 pie parts. the first circle (100%) has 5 parts. you should play with the fiddle to learn how it works and so you can replicate it. i've never done this before and am just looking at link San posted, but it looks like this just uses multiple Divs with the css3 TRANSFORM to form the curves, and the pseudo selectors :before and :after for animations. The animations occur as the page itself is loading... EG: :before div1 loads it has a transform of 5, it loads and has a transform of 8, :after it loads it has a transform of 11.

code:

<div class="half_pie">
    <div class="half_part_pie_one half_bar_color half_percentage" data-percentage="35"></div>
    <div class="half_part_pie_two"></div>
    <div class="half_part_pie_three"></div> <span class="half_pie_icon iconfont-android"></span>

Answer 3

This answer is only possible because of Turnip's answer, but I made a few significant changes, and I'll explain how it works as well:

.donutContainer {
    position: relative;
    float: left;
}

.donutContainer h2 {
    text-align:center;
    position: absolute;
    line-height: 125px;
    width: 100%;
}

svg {
    transform: rotate(-90deg);
}

.donut {
  stroke-dasharray: 440;
  -webkit-animation: donut 1s ease-out forwards;
  animation: donut 1s ease-out forwards;
}

@-webkit-keyframes donut {
  from {
    stroke-dashoffset: 440;
  }
}

@keyframes donut {
  from {
    stroke-dashoffset: 440;
  }
}

<div class="donutContainer">
    <h2>donut</h2>
    <svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">
     <g>
      <title>Layer 1</title>
      <circle id="circle" style="stroke-dashoffset: 160;/* 160 of 440 */" class="donut" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#69aff4" fill="none"/>
     </g>
    </svg>
</div>
<div class="donutContainer">
    <h2>donut 2</h2>
    <svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">
     <g>
      <title>Layer 1</title>
      <circle id="circle" style="stroke-dashoffset: 220;/* 220 of 440 */" class="donut" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#FEC007" fill="none"/>
     </g>
    </svg>
</div>

Because the animation uses from instead of to to create the animation, browsers that don't support the animation will show the donut chart complete, instead of not at all. This also makes it possible to change the colored in portion of the donut chart with just inline CSS, and the same single CSS animation can work for any number of donut charts.

An explaination for the svg stuff:

stroke-dasharray: In this case, basically the total circumference of the circle.

stroke-dashoffset: the portion of the circle that is colored in. Zero (0) means all colored in (100%), 440 (or whatever you set the circumference) for none of it colored in (0%)

Attributes on the circle element:

r: radius of the circle

cx: "center X". the center of the circle (X coordinate from bottom left of svg element)

cy: "center Y". the center of the circle (Y coordinate from bottom left of svg element)

stroke-width: width of the stroke that will draw the donut

stroke: color of the donut

Answer 4

In case you need to create a donut chart animation (just plain css) and also need multiple colors for it then check the codepen example I have created.

http://codepen.io/hilar47/pen/RprXev

<div class="container">
  <div class="donut-chart-block block"> 
    <div class="donut-chart">
        <div id="part1" class="portion-block"><div class="circle"></div></div>
        <div id="part2" class="portion-block"><div class="circle"></div></div>
        <div id="part3" class="portion-block"><div class="circle"></div></div>
        <p class="center"></p>        
    </div>

Answer 5

I have modified a snippet I found on the web to make a simple doughnut chart using only HTML and CSS, here is the result:

.block {
  margin: 25px 25px 0 0;
  background: #394264;
  border-radius: 5px;
  float: left;
  width: 300px;
  overflow: hidden;
}

.donut-chart-block {
  overflow: hidden;
}

.donut-chart {
  position: relative;
  width: 200px;
  height: 200px;
  margin: 2rem auto;
  border-radius: 100%
}

.donut-chart .center {
  background: #394264;
  position: absolute;
  top: 30px;
  left: 30px;
  height: 140px;
  width: 140px;
  border-radius: 70px;
}

.clip {
  border-radius: 50%;
  clip: rect(0px, 200px, 200px, 100px);
  height: 100%;
  position: absolute;
  width: 100%;
}

.item {
  border-radius: 50%;
  clip: rect(0px, 100px, 200px, 0px);
  height: 100%;
  position: absolute;
  width: 100%;
  font-family: monospace;
  font-size: 1.5rem;
}

#section1 {
  transform: rotate(0deg);
}

#section1 .item {
  background-color: #E64C65;
  transform: rotate(76deg);
}

#section2 {
  transform: rotate(76deg);
}

#section2 .item {
  background-color: #11A8AB;
  transform: rotate(140deg);
}

#section3 {
  transform: rotate(215deg);
}

#section3 .item {
  background-color: #4FC4F6;
  transform: rotate(113deg);
}

#section4 {
  transform: rotate(-32deg);
}

#section4 .item {
  background-color: #FCB150;
  transform: rotate(32deg);
}
