设置HTML页面最小高度为窗口高度的方法_html/css_WEB-ITnose
先看html和效果图
<!DOCTYPE html><html> <head> <style> body,p{ margin:0; } .header,.footer{ background:#000; height:60px; } /*兼容ie8 html,body{ height:100%; } */ .auto-height{ /*兼容ie8 min-height:100%; */ min-height:100vh; margin-top:-60px; margin-bottom:-60px; /*设置内边距方式一*/ box-sizing:border-box; padding-top:60px; padding-bottom:60px; } /*设置内边距方式二 .auto-height>div{ padding-top:60px; padding-botom:60px; } */ </style> </head> <body> <div class="header"> </div> <div class="main auto-height" id="main-con"> <div> <p>设置页面最小高度为窗口高度的方法</p> </div> </div> <div class="footer"> </div> <!-- script> var mainElem=document.getElementById("main-con"); document.onreadystatechange=function(){ if(document.readyState=="complete"){ mainElem.style.minHeight=(document.documentElement.clientHeight-120)+"px"; window.onresize=function(){ mainElem.style.minHeight=(document.documentElement.clientHeight-120)+"px"; }; } }; </script --> </body></html>效果图：
这里有两种方法：
第一种是使用css实现：
1. 给main元素添加样式：
min-height:100vh; margin-top:-60px;//数值等于页面头部高度 margin-bottom:-60px;//数值等于页面尾部高度
margin的高度是页面头部和尾部的高度。
2. 为了让main元素里的所有内容都显示出来，要增加相应的内边距，这里有两种方法：
box-sizing:border-box;//将main元素的宽高计算方式更改为包含内边距和边框 padding-top:60px;//数值等于页面头部高度 padding-botom:60px;//数值等于页面尾部高度
或设置其子元素的内边距：
.auto-height>div{ padding-top:60px;//数值等于页面头部高度 padding-botom:60px;//数值等于页面尾部高度 }3.由于ie8不支持vh单位，所以如果需要兼容ie8的话，可以将html和body的高度都设为100%，再设置main元素的最小高度为100%（min-height:100%），其他的设置不变。
html,body{ height:100%; }第二种是使用JavaScript来实现：
使用JavaScript来动态设置main元素的最小高度即可，这里提供其中一种实现方式
var mainElem=document.getElementById("main-con");//获得main元素 document.onreadystatechange=function(){ if(document.readyState=="complete"){//页面加载完成时执行 mainElem.style.minHeight=(document.documentElement.clientHeight-120)+"px";//初始化最小高度 window.onresize=function(){//窗口大小改变时改变main元素的最小高度 mainElem.style.minHeight=(document.documentElement.clientHeight-120)+"px"; }; } };最小高度的值=窗口的高度-页面头部高度-页面尾部高度。
