前端网页经典布局之双飞翼布局

方法一：利用 margin-left 为负值

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

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <style>
        * {
            margin: 0;
            padding: 0
        }

        .main {
            float: left;
            width: 100%;
        }


        .main .main-content {
            margin: 0 210px;
            background-color: rgba(33, 114, 214, 0.8);
            height: 500px
        }

        .left {
            width: 200px;
            float: left;
            background-color: rgba(255, 82, 0, 0.8);
            margin-left: -100%;
            height: 200px
        }

        .right {
            width: 200px;
            height: 200px;
            margin-left: -200px;
            float: left;
            background-color: rgba(90, 243, 151, 0.8);
        }
    </style>
</head>

<body>
    <div class="main">
        <div class="main-content">main content</div>
    </div>
    <div class="left">left</div>
    <div class="right">right</div>
</body>

</html>

方法二：利用 flex 布局

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

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        .container {
            width: 1200px;
            margin: 100px auto;
            display: flex;
        }

        .left {
            width: 200px;
            height: 300px;
            background-color: blueviolet
        }

        .right {
            width: 200px;
            height: 300px;
            background-color: pink
        }

        .center {
            flex: 1;
            height: 300px;
            background-color: coral;
        }
    </style>
</head>

<body>
    <div class="container">
        <div class="left"></div>
        <div class="center"></div>
        <div class="right"></div>
    </div>
</body>

</html>

方法三：利用 float + calc

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

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        .container {
            width: 1200px;
            height: 300px;
            margin: 100px auto;
        }

        .container>div {
            float: left;
            height: 100%;
        }

        .left {
            width: 200px;
            background-color: blueviolet
        }

        .right {
            width: 200px;
            background-color: pink
        }

        .center {
            width: calc(100% - 400px);
            background-color: coral;
        }
    </style>
</head>

<body>
    <div class="container">
        <div class="left"></div>
        <div class="center"></div>
        <div class="right"></div>
    </div>
</body>

</html>

方法四：利用定位

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

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        * {
            padding: 0;
            margin: 0;
        }

        .container {
            position: relative;
            height: 400px;
            width: 1200px;
            margin: 100px auto;
            border: 1px solid rgb(177, 172, 172);
        }

        .container>div {
            position: absolute;
            height: 100%;
        }

        .left {
            width: 200px;
            height: 300px;
            background-color: aqua;
        }

        .right {
            top: 0;
            right: 0;
            width: 200px;
            background-color: rgb(190, 96, 42);
        }

        .center {
            top: 0;
            right: 210px;
            left: 210px;
            background-color: cadetblue;
        }
    </style>
</head>

<body>
    <div class="container">
        <div class="left"></div>
        <div class="center"></div>
        <div class="right"></div>
    </div>
</body>
