How to segment a circle with different colors using CSS

Question

I want to be able to draw a circle with a segment of it another colour, I would like the amount of a segment covered to be able to be increased in increments of 10% from 0% to 100%.

Any examples on Google are all sectors not segments.

So far this is the best I have been able to come up with:

div.outerClass {
    position: absolute;
    left: 10px;
    top: 10px;
    height: 2.5px;
    overflow: hidden;
    -ms-transform: rotate(270deg); /* IE 9 */
    -webkit-transform: rotate(270deg); /* Chrome, Safari, Opera */
    transform: rotate(270deg);
}

div.innerClass {
    width: 10px;
    height: 10px;
    border: 5px solid green;
    border-radius: 36px;
}

<div class="outerClass">
    <div class="innerClass"></div>
</div>

0%, 50% and 100% I can all do.

The cross-browser solution:

JSFiddle

.circle {
    border-radius: 50%;
    background: gray;
    width: 300px;
    height: 300px;
    overflow: hidden;
}
.segment {
    float: left;
    width: 10%;
    height: 100%;
}
    .segment_1 {
        background: red;
    }
    .segment_2 {
        background: green;
    }
    .segment_3 {
        background: yellow;
    }
    .segment_4 {
        background: blue;
    }

<div class="circle">
    <div class="segment segment_1"></div>
    <div class="segment segment_2"></div>
    <div class="segment segment_3"></div>
    <div class="segment segment_4"></div>
</div>

Another approach would be to use SVG. The segments are made with <rect /> elements and they are clipped to a circle using the <clipPath/> element :

svg{width:40%;display:block;margin:0 auto;}
use:hover{fill:#000;}

<svg viewBox="0 0 10 10">
  <defs>
    <clipPath id="circle">
      <circle cx="5" cy="5" r="5" />
    </clipPath>
    <rect id="seg" y="0" width="1" height="10" />
  </defs>  
  <g clip-path="url(#circle)">
    <use xlink:href="#seg" x="0" fill="pink"/>
    <use xlink:href="#seg" x="1" fill="green" />
    <use xlink:href="#seg" x="2" fill="orange" />
    <use xlink:href="#seg" x="3" fill="teal" />
    <use xlink:href="#seg" x="4" fill="tomato"/>
    <use xlink:href="#seg" x="5" fill="gold"/>
    <use xlink:href="#seg" x="6" fill="darkorange" />
    <use xlink:href="#seg" x="7" fill="pink" />
    <use xlink:href="#seg" x="8" fill="red" />
    <use xlink:href="#seg" x="9" fill="yellow" />
  </g>
</svg>

BOX SHADOW

Another approach could be using one element and box-shadows.

• The main element is a circle (border-radius: 50%;) and has an aspect ratio of 1:1.

• The pseudoelement is positioned left: -100%;, or just left of the main element.

• 10 box shadows are applied to the pseudoelement, with different colour and different abscissae. I have put abscissae as 30px, as 30px is 10% of 300px ...

• 10% of width was chosen because 10 stripes are needed.

div {
  height: 300px;
  width: 300px;
  border: 1px solid black;
  position: relative;
  border-radius: 50%;
  overflow: hidden;
}
div:before {
  position: absolute;
  content: '';
  height: inherit;
  width: inherit;
  left: -100%;
  background: red;
  box-shadow: 
    30px 0 0 chocolate,
    60px 0 0 hotpink,
    90px 0 0 indigo,
    120px 0 0 orangered,
    150px 0 0 gold,
    180px 0 0 deepskyblue,
    210px 0 0 springgreen,
    240px 0 0 darkslategray,
    270px 0 0 gold,
    300px 0 0 navy;
}

You can do it using linear-gradient

.circle{
  position:absolute;
  width:80px;
  height:80px;
  border-radius:50%;
  background: linear-gradient(
    to right,
    yellow  0%, yellow 10%,
    orange 10%, orange 20%,
    yellow 20%, yellow 30%,
    orange 30%, orange 40%,
    yellow 40%, yellow 50%,
    orange 50%, orange 60%,
    yellow 60%, yellow 70%,
    orange 70%, orange 80%,
    yellow 80%, yellow 90%,
    orange 90%, orange 100%
  );
}

<div class="circle"></div>

otherwise you can put 10 child elements inside your overflow:hidden circle parent:

.circle{
  position:absolute;
  width:80px;
  height:80px;
  border-radius:50%;
  overflow:hidden;
}
.circle > span{
  width:10%;
  height:100%;
  float:left;
}

.circle > span:nth-child(1){ background: yellow;}
.circle > span:nth-child(2){ background: orange;}
.circle > span:nth-child(3){ background: blue;}
.circle > span:nth-child(4){ background: green;}
.circle > span:nth-child(5){ background: fuchsia;}
.circle > span:nth-child(6){ background: orange;}
.circle > span:nth-child(7){ background: gold;}
.circle > span:nth-child(8){ background: tan;}
.circle > span:nth-child(9){ background: navy;}
.circle > span:nth-child(10){background: brown;}

<div class="circle">
  <span></span><span></span><span></span><span></span><span></span>
  <span></span><span></span><span></span><span></span><span></span>
</div>
