左中右,自适应,布局在最新的html标准中 有了个calc css表达式,我们可以用这个来计算布局。 但是在古老的IE中,却不支持,为了所有浏览器的支持,这里用了js来做。 截图: code:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD LEVEL1//EN"> <html> <head> <title>MyHtml.html</title> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="this is my page"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <script> var left,center,right,width; window.onload=function(){ left=$('left'); center=$('center'); right=$('right'); onresize(); }; window.onresize=function(){ try { width = document.body.clientWidth; center.style.width = (width - left.clientWidth - right.clientWidth - 0) + "px"; }catch(e){ //小于0会报错 } }; function $(id){ return document.getElementById(id); } </script> <style> body,html{ height:100%; margin:0px; padding:0px; overflow:hidden; } #left,#center,#right{ width:200px; height:100px; background-color:rgb(34,124,134); float:left; height:100%; } #center{ background-color:red; } </style> </head> <body> <div id="left"></div> <div id="center"></div> <div id="right"></div> </body> </html>
