写在前面：我们在网页中使用图形会经常使用图片或者字体图标，其实用纯css一样也可以画出很多看似复杂的形状,这篇文章就来介绍一下这方面的东西。

一.基本图形
下面每个例子的html只需要创建一个相应id的div,正方形，长方形就不用介绍了。
<div id="id-name"></div>

1.Circle(圆形)

#circle {
    width: 100px;
    height: 100px;
    background: red;
    -moz-border-radius: 50px;
    -webkit-border-radius: 50px;
    border-radius: 50px;
}

2.Oval(椭圆形)

#oval {
    width: 200px;
    height: 100px;
    background: red;
    -moz-border-radius: 100px / 50px;
    -webkit-border-radius: 100px / 50px;
    border-radius: 100px / 50px;
}

3.Triangle(三角形）

/*向上的三角形*/

#triangle-up {
    width: 0;
    height: 0;
    border-left: 50px solid transparent;
    border-right: 50px solid transparent;
    border-bottom: 100px solid red;
}

/*向下的三角形*/

#triangle-down {
    width: 0;
    height: 0;
    border-left: 50px solid transparent;
    border-right: 50px solid transparent;
    border-top: 100px solid red;
}

/*向左的三角形*/

#triangle-left {
    width: 0;
    height: 0;
    border-top: 50px solid transparent;
    border-right: 100px solid red;
    border-bottom: 50px solid transparent;
}

/*向右的三角形*/

#triangle-right {
    width: 0;
    height: 0;
    border-top: 50px solid transparent;
    border-left: 100px solid red;
    border-bottom: 50px solid transparent;
}

/*左上的三角形*/

#triangle-topleft {
    width: 0;
    height: 0;
    border-top: 100px solid red;
    border-right: 100px solid transparent;
}

/*右上的三角形*/

#triangle-topright {
    width: 0;
    height: 0;
    border-top: 100px solid red;
    border-left: 100px solid transparent;
}

/*左下的三角形*/

#triangle-bottomleft {
    width: 0;
    height: 0;
    border-bottom: 100px solid red;
    border-right: 100px solid transparent;
}

/*右下的三角形*/

    width: 0;
    height: 0;
    border-bottom: 100px solid red;
    border-left: 100px solid transparent;
