如果网页要用到五角星，我们通常想到的最直接方法是在Ps里面绘制一个五角星再存成图片插入网页中，下面我们就来看看如何通过CSS绘制五角星：

网页代码：

CSS样式

#star-five {
margin: 50px 0;
position: relative;
display: block;
color: red;
width: 0px;
height: 0px;
border-right: 100px solid transparent;
border-bottom: 70px solid red;
border-left: 100px solid transparent;
-moz-transform: rotate(35deg);
-webkit-transform: rotate(35deg);
-ms-transform: rotate(35deg);
-o-transform: rotate(35deg);
}
#star-five:before {
border-bottom: 80px solid red;
border-left: 30px solid transparent;
border-right: 30px solid transparent;
position: absolute;
height: 0;
width: 0;
top: -45px;
left: -65px;
display: block;
content: ”;
-webkit-transform: rotate(-35deg);
-moz-transform: rotate(-35deg);
-ms-transform: rotate(-35deg);
-o-transform: rotate(-35deg);

}
#star-five:after {
position: absolute;
display: block;
color: red;
top: 3px;
left: -105px;
width: 0px;
height: 0px;
border-right: 100px solid transparent;
border-bottom: 70px solid red;
border-left: 100px solid transparent;
-webkit-transform: rotate(-70deg);
-moz-transform: rotate(-70deg);
-ms-transform: rotate(-70deg);
-o-transform: rotate(-70deg);
content: ”;
}

五边形：

#pentagon {
position: relative;
width: 54px;
border-width: 50px 18px 0;
border-style: solid;
border-color: red transparent;
}
#pentagon:before {
content: “”;
position: absolute;
height: 0;
width: 0;
top: -85px;
left: -18px;
border-width: 0 45px 35px;
border-style: solid;
border-color: transparent transparent red;
}

最终效果：
