利用border编写空心三角箭头的两种办法

作者

之前一直在寻找这种空心三角箭头, 终于知道了原理! 自己记录一下,顺便分享给之前跟我一样想要的撸友们~

第一种写法 利用常见的 after伪元素

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title></title>

        <style type="text/css">

            .arrow {

                width: 20px;

                height: 4px;

                margin: 0 auto 7px;

                border-left: 4px solid transparent;

                border-right: 4px solid transparent;

                border-bottom: 4px solid #343c99;

                transform: rotate(45deg);

                transform-origin: left;

            }

             

            .arrow:after {

                content: '';

                display: block;

                width: 100%;

                height: 100%;

                border-left: 4px solid transparent;

                border-right: 4px solid transparent;

                border-top: 4px solid #343c99;

                position: absolute;

                right: -10px;

                top: -14px;

                transform: rotate(90deg);

                transform-origin: bottom;

            }

        </style>

    </head>

    <body>

        <div class="arrow"></div>

    </body>

</html>

第二种写法相对于比较简单

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title></title>

        <style type="text/css">

            /*简单*/

            .wb_arrow{

                border-right: 2px solid #343c99;

                border-top: 2px solid #343c99;

                height: 10px;

                width: 10px;

                margin:50px auto 0;

                transform: rotate(deg);

                -webkit-transform: rotate(0deg);

                /*不加这两个属性三角会比上一个略丑, 大家可以试一下*/

                border-left: 2px solid transparent;

                border-bottom: 2px solid transparent;

            }

        </style>

    </head>

    <body>

        <div class="wb_arrow"></div>

    </body>

</html>
