一个简单的三角形运用页面

原理就是宽高为0，设置边框就是三角形了，

然后加点定位到自己想要的地方。

.sjx{
    				margin: auto;
    				width: 0;
    				height: 0;
    			    border:10px solid transparent;
    				border-top: 10px solid #000000;
    				position: relative;
    				top: 20%;
    			}

如果要还角度，再次改变border的top bottom left  和right就可以了，颜色也可以直接换

进阶三角形：

可以用js 改变class br bc  tr tc 来改变颜色用于显示正序还是倒序。
