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:

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;
  }
}

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

.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;
  }
}

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.
