CSS補充之頁面佈局

主站一：（下面是一個大體的模板）css

<body>
    <div class="pg-header">
        <div style="width: 980px;margin: 0 auto;">
                這裏的內容會自動居中
        </div>
    </div>
    <div class="pg-content"></div>
    <div class="pg-footer"></div>
</body>

這樣是把網站分爲了上中下三部分，最上面是頭部，中間是主要內容，下面是底部的信息。html

後臺管理佈局

佈局一，效果圖以下：web

當滑動右邊滾動條的時候其餘區域保持不變只有aaa佔的部分會發生滾動佈局

代碼實現以下：網站

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        body{
            margin: 0;
        }
        .pg-header{
            height: 48px;
            background-color: #2459a2;
            color: white;
        }
        .left{
            float: left;
        }
        .right{
            float: right;
        }
        .pg-content .menu{
            position: fixed;
            top: 48px;
            left: 0;
            bottom: 0;
            width: 200px;
            background-color: #dddddd;
        }
        .pg-content .content{
            position: fixed;
            top: 48px;
            bottom: 0;
            right: 0;
            left: 200px;
            background-color:green;
            overflow: auto;
        }
    </style>
</head>
<body>
    <div class="pg-header"></div>
    <div class="pg-content">
        <div class="menu left">a</div>
        <div class="content left">
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>

            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>

            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>

            <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>

        </div>
    </div>
    <div class="pg-footer"></div>
</body>

佈局二，效果圖以下（這種是必須會的，後臺佈局常常用）spa

這種狀況是當滑動滾輪的時候，左邊菜單不會跟着走，即：code

由於滑動，左邊已經沒有菜單，實現代碼以下：htm

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        body{
            margin: auto;
        }
        .pg-header{
            height: 48px;
            background-color: #2459a2;
            color: white;
        }
        .left{
            float: left;
        }
        .right{
            float: right;
        }
        .pg-content .menu{
            position: absolute;
            top: 48px;
            left:0;
            bottom: 0;
            width: 200px;
            background-color: #dddddd;
        }
        .pg-content .content{
            position: absolute;
            top: 48px;
            right: 0;
            bottom: 0;
            left:200px;
        }
    </style>
</head>
<body>
    <div class="pg-header"></div>
    <div class="pg-content">
        <div class="menu left">a</div>
        <div class="content left">
            <div style="background: green;">
                <p style="margin: 0">aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>
                <p>aaa</p><p>aaa</p><p>aaa</p><p>aaa</p>

            </div>

        </div>
    </div>
    <div class="pg-footer"></div>
</body>
</html>

還有當頁面縮小到必定程度時，爲了防止頁面的內容顯示發生變化，左右會出現滾動條，效果以下所示：blog

只需設置min-width 參數便可：圖片

        .pg-content .content{
            position: absolute;
            top: 48px;
            right: 0;
            bottom: 0;
            left:200px;
            min-width: 980px;
        }

其實這裏若是想要和佈局一有相同的效果只須要更改一個地方就能夠實現：（這種設置用的也是最多的）

        .pg-content .content{
            position: absolute;
            top: 48px;
            right: 0;
            bottom: 0;
            left:200px;
            min-width: 980px;
            overflow: auto;
        }

作一個簡單的後臺管理頁面

首先須要記住一個地址：

http://fontawesome.io/

這個地址中存放了咱們須要的各類圖標，以下所示：

將文件下載下來

經過在頭部導入：

作出的效果圖以下所示：

當把鼠標放在頭像的時候顯示資料和註銷信息，圖片中的圖標就是從下載的圖標中直接引用的

實現代碼以下：

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

            background-color: #2459a2;
            color: white;
            min-width: 500px;
            line-height: 48px;
        }
        .pg-header .icons{
            padding: 0 20px;

            background-color: blue;
