如何使用CSS分割不同颜色的圆圈

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.

Answer 1

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> 

Answer 2

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> 

Answer 3

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; } 

 <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>
