我想做的是创建一个简单的圆环图。我目前只使用CSS(3),但我不知道没有javascript是否可行。
到目前为止我所拥有的: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;
}
我想展示绿色和蓝色作为主题。所以没有绿色是0%,全绿色(360度)是100%。如果可能的话,甚至可以在加载图表时使用简单的动画。
非常感谢你的帮助。
SVG获胜!

它是如何工作的
stroke-dasharray
用于定义虚线使用的"模式"(MDN)。通过提供一个值,您可以创建一个破折号为440px、空格为440px的图案。(440px大约是圆的周长)。
CCD_ 2有效地移动了虚线图案(MDN)的起始点。
220的dash-offset
(stroke-dasharray
的一半)将产生半圆。110=四分之一圆等
这个答案之所以可能,是因为Turnip的答案,但我做了一些重大更改,我将解释它是如何工作的:
.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">

因为动画使用from
而不是to
来创建动画,所以不支持动画的浏览器将显示完整的圆环图,而不是完全不显示。这也使得只使用内联CSS就可以更改圆环图的彩色部分,并且相同的单个CSS动画可以适用于任何数量的圆环图。
svg
物质的解释:
stroke-dasharray
:在这种情况下,基本上是圆的总周长。
stroke-dashoffset
:圆圈中着色的部分。零(0)表示所有着色在(100%)中,440(或您设置的周长)表示没有着色在(0%)中
circle
元素的属性:
r
:圆的半径
CCD_ 12:";中心X";。圆心(svg
元素左下角的X坐标)
CCD_ 14:";中心Y";。圆心(svg
元素左下角的Y坐标)
stroke-width
:绘制圆环的笔划宽度
stroke
:甜甜圈的颜色
我写了这篇评论回复,但太长了:
嗯。。。哦,这是第二圈的小提琴http://jsfiddle.net/LgtV2/。。。。它有三个馅饼部分。第一个圆(100%)有5个部分。你应该掌握它的工作原理,这样你就可以复制它了。我以前从来没有这样做过,我只是在看San发布的链接,但它看起来只是使用了多个Div和css3TRANSFORM来形成曲线,以及用于动画的伪选择器:before和:after。动画在加载页面时发生。。。例如:在加载div1之前,它有一个5的变换,它加载并有一个8的变换,:在加载之后,它有11的变换。
