几个实现两栏布局的方法（左侧固定，右侧自适应）

一、position（定位）

<!doctype html>
<html>

<head>
    <meta http-equiv="ContentType" content="text/html;charset=utf-8">
    <title>两栏布局</title>
    <style>
    .container{
        position: relative;
    }

    .left{
        position: absolute;
        width: 200px;
        background-color:brown; 
        height: 300px;
    }

    .right{
        width: 100%;
        background-color: blue;
        height: 300px;
    }
    </style>
</head>

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

</html>

二、float（浮动）

<!doctype html>
<html>

<head>
    <meta http-equiv="ContentType" content="text/html;charset=utf-8">
    <title>两栏布局</title>
    <style>

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

    .right{
        width: 100%;
        background-color: blue;
        height: 300px;
    }
    </style>
</head>

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

</html>

浮动元素会对后一个元素产生影响，对前一个不会，后一个元素会围着float元素。解决办法：clear属性或BFC。

三、flex（弹性盒子）

<!doctype html>
<html>

<head>
    <meta http-equiv="ContentType" content="text/html;charset=utf-8">
    <title>两栏布局</title>
    <style>
        .container {
            display: flex;
        }

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

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

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

</html>

四、margin-left（类似双飞翼布局）

<!doctype html>
<html>

<head>
    <meta http-equiv="ContentType" content="text/html;charset=utf-8">
    <title>两栏布局</title>
    <style>
        .left {
            float: left;
            width: 200px;
            background-color: brown;
            height: 300px;
            margin-left: -100%;
        }

        .right {
            float: left;
            width: 100%;
            background-color: blue;
            height: 300px;
        }

        .inner {
            height: 300px;
            padding: 0 0 0 200px;
        }
    </style>
</head>

<body>
    <div class="right"></div>
    <div class="left">
        <div class="inner"></div>
    </div>
    </div>
</body>

</html>
