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）

图形：

代码：
