一、Css 斜線，塊斜線，對角線

塊的寬度高度任意支援

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>

    <style>
        /* 1 */
        .block {
            height: 100px;
            border: 1px solid red;
            position: relative;
            overflow: hidden;
        }


        .block::before {
            content: '';
            position: absolute;
            width: 0;
            height: 0;
            left: 0px;
            top: 0;
            width: 100%;
            height: 100%;
            background: linear-gradient(to right top, #00f 50%, #fff 50%);
        }

        .block::after {
            content: '';
            position: absolute;
            width: 0;
            height: 0;
            left: -1px;
            top: 1px;
            width: 100%;
            height: 100%;
            background: linear-gradient(to right top, #fff 50%, transparent 50%);
        }
    </style>
</head>

<body>

    <div class="block"></div>

</body>

</html>

二、Css 斜線對角線，正方形對角線推薦

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>

    <style>
        /* 2 */

        .block2 {
            height: 100px;
            width: 100px;
            position: relative;
            overflow: hidden;
            background: yellow;
            margin: 50px auto;
        }

        /* 2.1 */
        .block2::after {
            content: '';
            position: absolute;
            left: 50%;
            top: 50%;
            height: 150px;
            width: 1px;
            background: #888888;
            transform: translate(-50%, -50%) rotate(-45deg);
        }
    </style>
</head>

<body>

    <div class="block2"></div>

</body>

</html>

三、css 對角線，漸變實現，粗細度不好控制，寬高不能太大

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        /* 3 */
        .block3 {
            box-sizing: border-box;
            background: yellowgreen;
            width: 200px;
            text-align: center;
            margin: auto;
            padding: 100px 0px;
            position: relative;
        }

        .block3::after {
            content: '';
            position: absolute;
            left: 0;
            top: 0;
            width: 100%;
            height: 100%;
            background: linear-gradient(to right top, transparent 49%, #000, transparent 50%);
        }
    </style>
</head>

<body>

    <div class="block3">
        張三丰的店
    </div>
</body>

</html>
