一、三角形
.father {
width: 0px;
height: 0px;
border: 50px solid black;
}
只设置border
.father {
width: 0px;
height: 0px;
border-top: 50px solid black;
border-right: 50px solid red;
border-bottom: 50px solid green;
border-left: 50px solid blue;
}
设置四个border
// transparent 关键字表示一个完全透明的颜色，即该颜色看上去将是背景色
.father {
width: 0px;
height: 0px;
border-top: 50px solid black;
border-right: 50px solid transparent;
border-bottom: 50px solid transparent;
border-left: 50px solid transparent;
}
.caret {
width: 0;
height: 0;
border: 50px solid transparent;
border-top-color: black;
}

.father {
width: 0px;
height: 0px;
border-top: 50px solid black;
border-left: 50px solid transparent;
border-right: 50px solid transparent;
}
节省空间的三角形
// 等腰梯形
.father {
width: 50px;
height: 0px;
border-top: 50px solid black;
border-left: 50px solid transparent;
border-right: 50px solid transparent;
}
