1. 常见的flex 布局

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

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>height-flex-position-table</title>
</head>
<style>
/** html  和body  记得给宽高设定 margin重新给值为0;**/
    html,
    body {
        width: 100%;
        height: 100%;
        margin: 0;
    }
    
    .main {
        height: 100%;
        width: 100%;
        display: flex;/*盒模型*/
        flex-direction: column;/*纵向布局*/
    }
    
    .head {
        width: 100%;
        height: 200px;
        background: yellow;
    }
    
    .content {
        flex: 1;
        background: blue;
    }
    
    .footer {
        width: 100%;
        height: 200px;
        background: red;
    }
</style>

<body>
    <div class="main">
        <div class="head">head</div>
        <div class="content">
            <div>12</div>
            <div>12</div>
            <div>12</div>
        </div>
        <div class="footer">footer</div>
    </div>
</body>

</html>

2.position :absolute 绝对定位布局

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

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>height-flex-position-table</title>
</head>
<style>
    html,
    body {
        width: 100%;
        height: 100%;
        margin: 0;
    }
    
    .main {
        height: 100%;
        width: 100%;
    }
    
    .head {
        width: 100%;
        height: 200px;
        background: yellow;
    }
    
    .content {
        position: absolute;
        bottom: 200px;
        top: 200px;
        background: blue;
    }
    
    .footer {
        width: 100%;
        height: 200px;
        position: absolute;
        bottom: 0;
        background: red;
    }
</style>

<body>
    <div class="main">
        <div class="head">head</div>
        <div class="content">
            <div>12</div>
            <div>12</div>
            <div>12</div>
        </div>
        <div class="footer">footer</div>
    </div>
</body>

</html>

3. display:table 实现布局效果

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

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>height-flex-position-table</title>
</head>
<style>
    html,
    body {
        width: 100%;
        height: 100%;
        margin: 0;
    }
    
    .main {
        height: 100%;
        width: 100%;
        display: table;
    }
    
    .head {
        width: 100%;
        height: 200px;
        display: table-row;
        background: yellow;
    }
    
    .content {
        display: table-row;
        background: blue;
    }
    
    .footer {
        width: 100%;
        height: 200px;
        display: table-row;
        background: red;
    }
</style>

<body>
    <div class="main">
        <div class="head">head</div>
        <div class="content">
            <div>12</div>
            <div>12</div>
            <div>12</div>
            <div>12</div>
            <div>12</div>
            <div>12</div>
        </div>
        <div class="footer">footer</div>
    </div>
</body>
