如何在css中绘制特殊图形？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
一、三角形
border边框设置
代码：
width: 300px; height: 300px; background: red; border: 40px solid black; border-left-color: blue; border-bottom-color: yellow; border-right-color: pink; border-top-color: #008800;
花特殊图形的时候需要将宽高设置成0
效果：
代码：
width: 0; height: 0; background: transparent; border: 40px solid black; border-left-color: blue; border-bottom-color: yellow; border-right-color: pink; border-top-color: #008800;
1、等腰三角形：将其他的边的border设置成透明
代码：
width:0; height: 0; background: transparent; border: 40px solid black; border-left-color: transparent; border-bottom-color: yellow; border-right-color: transparent; border-top-color: transparent;
2、直角三角形
代码：先写出个完整的div,再使用border-***-width：0；来截取三角形
border-top-width/border-bottom-width:0=》就是在中间横着劈开一道，保留上边或者下边
border-left-width/border-right-width:0=》就是在中间竖着劈开一道，保留左边或者右边
.rightAngle{
width: 0;
height: 0;
background: transparent;
border: 40px solid black;
border-left-color: blue;
border-bottom-color: yellow;
border-right-color: pink;
border-top-color: #008800;
border-top-width: 0;
border-left-width: 0;
border-right-color: transparent;
}3、梯形
彩带图形：
代码：
width: 300px; height: 0; background: transparent; border: 40px solid #008800; border-left-color: transparent; border-bottom-color: yellow; border-right-color: transparent; border-top-color: #008800;
梯形：
代码：将上面彩带图形的宽度减少，然后将上面的梯形设置为透明
width: 100px; height: 0; background: transparent; border: 40px solid #008800; border-left-color: transparent; border-bottom-color: #008800; border-right-color: transparent; border-top-color: transparent;
总结：通过设置长度和高度，以及设置border的透明度来拼凑成想要的图形 4、圆形
4、图形：
代码： 使用border-radius:50%;
.circle{
width: 100px;
height: 100px;
border: 0;
border-radius: 50%;
background-color: orange;
}5、椭圆
图形：
代码：
.ellipse{
width: 200px;
height: 120px;
background-color: orange;
border-top-left-radius: 50%;
border-top-right-radius: 50%;
border-bottom-left-radius: 50%;
border-bottom-right-radius: 50%;
}总结：
一个display：block的元素设定宽高之后表现为矩形。通过设定border-radius可以得到圆角矩形，圆形和椭圆形。
在使用border-radius时，有几点可能需要注意一下：
border-radius，可以分别对4个角进行设定。 例如上图：border-top-left-radius: apx bpx;
border-xxx-xxx-radius的两个值分别代表着椭圆长轴和短轴长度的一半，通常简写的时候例如border-top-left-radius: 10px;(border-top-left-radius:10px 10px;) 表明长轴和短轴的长度均为20px，也就是半径为10px的圆形（圆角部分）。
当使用百分比数值时，a 相对于width， b相对于height 6、特殊图形
（1）斜边三角形
图形：
代码：先画个等边三角形，然后再转换角度
.beveledTriangle{
margin: 50px;
width: 0;
height: 0;
border: 20px solid #2b81af;
border-top-width: 40px;
border-top-color:transparent;
border-bottom-width: 40px;
border-bottom-color: transparent;
border-left-width: 0;
border-right-color: #008800;
border-right-width: 25px;
transform-origin:center center;
transform:rotateY(-180deg) rotate(-44deg) ;
}（2）绘制一条“小尾巴”
图形：
代码：
.tail{
margin: 50px;
width: 100px;
height: 70px;
border-top-right-radius: 70px 70px;
border-right:6px solid #000000;
}总结：当对一个角应用圆角样式， 如果这个角相邻的两个boeder一个有定义而一个无定义 ，那么绘制的结果就是有粗到细的“小尾巴了”
7、绘制QQ图案（取自AlloyTeam案例）
