具体代码如下
html代码:
<div id="content"><div class="legend"><h1>汽车销量:</h1><div class="skills"><ul><li class="jq">大众</li><li class="css">丰田</li><li class="html">别克</li><li class="php">福特</li><li class="sql">长安</li></ul></div></div><div id="diagram"></div></div><div class="get"><div class="arc"><span class="text">大众</span><input type="hidden" class="percent" value="95" /><input type="hidden" class="color" value="#97BE0D" /></div><div class="arc"><span class="text">丰田</span><input type="hidden" class="percent" value="90" /><input type="hidden" class="color" value="#D84F5F" /></div><div class="arc"><span class="text">别克</span><input type="hidden" class="percent" value="80" /><input type="hidden" class="color" value="#88B8E6" /></div><div class="arc"><span class="text">福特</span><input type="hidden" class="percent" value="53" /><input type="hidden" class="color" value="#BEDBE9" /></div><div class="arc"><span class="text">长安</span><input type="hidden" class="percent" value="45" /><input type="hidden" class="color" value="#EDEBEE" /></div></div>css代码:
