CSS全屏布局的5种方式

标签：bottom   hidden   middle   元素   parent   

思路一: float

【1】float + calc

　　通过calc()函数计算出.middle元素的高度，并设置子元素高度为100%

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.middle{
    overflow: hidden;
    height: calc(100% - 100px);}.left{
    float: left;
    width: 100px;
    margin-right: 20px;
    height: 100%;}.right{
    overflow: auto;
    height: 100%;}.right-in{
    height: 1000px;}.top,.bottom{height:50px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div>  
    <div class="middle" style="background-color: pink;">
        <div class="left" style="background-color: orange;">
            <p>left</p>
        </div>
        <div class="right" style="background-color: lightsalmon;">
            <div class="right-in">
                <p>right</p>
            </div>
        </div>
    </div>          
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>

【2】float + absolute + (fix)

　　通过增加结构来提高兼容性，.middle元素设置100%的高度，.top和.bottom设置absolute覆盖在.middle上

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.top,.bottom{
    position: absolute;
    height:50px;
    left: 0;
    right: 0;}.top{top: 0;}.bottom{bottom: 0;}.middleWrap{
    height: 100%;
    overflow: hidden;}.middle{
    overflow: hidden;
    height: 100%;
    margin: 50px 0;}.left{
    float: left;
    width: 100px;
    margin-right: 20px;
    height: 100%;}.right{
    overflow: auto;
    height: 100%;}.right-in{
    height: 1000px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div>  
    <div class="middleWrap">
        <div class="middle" style="background-color: pink;">
            <div class="left" style="background-color: orange;">
                <p>left</p>
            </div>
            <div class="right" style="background-color: lightsalmon;">
                <div class="right-in">
                    <p>right</p>
                </div>
            </div>
        </div>        
    </div> 
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>

思路二: inline-block

【1】inline-block + calc

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.middle{
    height: calc(100% - 100px);
    font-size: 0;}.left,.right{
    display: inline-block;
    vertical-align: top;
    font-size: 16px;}.left{
    width: 100px;
    margin-right: 20px;
    height: 100%;}.right{
    width: calc(100% - 120px);
    height: 100%;
    overflow: auto;}.right-in{
    height: 1000px;}.top,.bottom{height: 50px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div>  
    <div class="middle" style="background-color: pink;">
        <div class="left" style="background-color: orange;">
            <p>left</p>
        </div>
        <div class="right" style="background-color: lightsalmon;">
            <div class="right-in">
                <p>right</p>
            </div>
        </div>
    </div>        
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>

【2】inline-block + absolute + (fix)

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.top,.bottom{
    position: absolute;
    left: 0;
    right: 0;
    height: 50px;}.top{top: 0;}.bottom{bottom: 0;}.middleWrap{
    height: 100%;
    font-size: 0;
    overflow: hidden;}.middle{
    position: relative;
    height: 100%;
    margin: 50px 0;
    overflow: hidden;}.left,.rightWrap{
    display: inline-block;
    vertical-align: top;
    font-size: 16px;}.left{
    position: absolute;
    width: 100px;
    margin-right: 20px;
    height: 100%;}.rightWrap{
    width: 100%;
    height: 100%;}.right{
    height: 100%;
    margin-left: 120px;
    overflow: auto;}.right-in{
    height: 1000px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div>  
    <div class="middleWrap">
        <div class="middle" style="background-color: pink;">
            <div class="left" style="background-color: orange;">
                <p>left</p>
            </div>
            <div class="rightWrap">
                <div class="right" style="background-color: lightsalmon;">
                    <div class="right-in">
                        <p>right</p>
                    </div>
                </div>                
            </div>
        </div>         
    </div>
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>

思路三: table

　　水平方向子元素的间距可以用border实现。所有浏览器都不支持给table-cell元素设置overflow属性。firefox和IE11浏览器不支持给table-cell元素的设置100%高度的子元素设置overflow属性

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.top,.bottom{
    position: absolute;
    width: 100%;
    height: 50px;}.bottom{bottom: 0;}.middleWrap{
    height: 100%;
    overflow: hidden;}.middle{
    width: 100%;
    height: 100%;
    display: table;    
    margin: 50px 0;
    table-layout: fixed;}.left{
    display: table-cell;
    width: 120px;
    border-right: 20px solid lightgray;}.rightWrap{
    display: table-cell;
    height: 100%;}.right{
    height: 100%;
    overflow: auto;}.right-in{
    height: 1000px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div> 
    <div class="middleWrap">
        <div class="middle" style="background-color: pink;">
            <div class="left" style="background-color: orange;">
                <p>left</p>
            </div>     
            <div class="rightWrap">
                <div class="right" style="background-color: lightsalmon;">
                    <div class="right-in">
                        <p>right</p>
                    </div>            
                </div>                    
            </div>   
        </div>         
    </div>    
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>

思路四: absolute

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.top,.middle,.bottom{
    position: absolute;
    left: 0;
    right: 0;}.top{
    top: 0;
    height: 50px;}.bottom{
    bottom: 0;
    height: 50px;}.middle{
    top: 50px;
    bottom: 50px;}.left,.right{
    position: absolute;
    top: 0;
    bottom: 0;}.left{
    width:100px;}.right{
    left: 120px;
    right: 0;
    overflow: auto;}.right-in{
    height: 1000px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div> 
    <div class="middle" style="background-color: pink;">
        <div class="left" style="background-color: orange;">
            <p>left</p>
        </div>     
        <div class="right" style="background-color: lightsalmon;">
            <div class="right-in">
                <p>right</p>
            </div>            
        </div>                    
    </div>              
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>

思路五: flex

　　flex常用于小范围的布局，使用全屏布局时会因为性能问题，出现卡顿现象。如果要使用全屏自适应布局，则只有flex才能达到效果

<style>body,p{margin: 0;}body,html,.parent{height: 100%;}.parent{
    display: flex;
    flex-direction: column;}.top,.bottom{
    height: 50px;}.middle{
    display: flex;
    flex: 1;}.left{
    width: 100px;
    margin-right: 20px;}.right{
    flex: 1;
    overflow: auto;}.right-in{
    height: 1000px;}</style>

<div class="parent" id="parent" style="background-color: lightgrey;">
    <div class="top" style="background-color: lightblue;">
        <p>top</p>
    </div> 
    <div class="middle" style="background-color: pink;">
        <div class="left" style="background-color: orange;">
            <p>left</p>
        </div>     
        <div class="right" style="background-color: lightsalmon;">
            <div class="right-in">
                <p>right</p>
            </div>            
        </div>                    
    </div>              
    <div class="bottom" style="background-color: lightgreen;">
        <p>bottom</p>
    </div>        </div>
