宽高设为0，border设置宽度，三边透明transparent ，三角形底部方向设置颜色，就可以实现三角形了

<!DOCTYPE html>

    <style>
        .triangle {
            width: 0;
            height: 0;
            border-style: solid;
            border-width: 50px;
            border-color: transparent transparent red transparent;
        }

        /* 简写版 */
        .triangle2 {
            width: 0;
            height: 0;
            border: 50px solid transparent;

        }
    </style>
</head>
