css布局(三列布局、响应式布局、流式布局)
一、三列布局
(1)两边固定 (先float左右固定值,再middle 用margin)
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>无标题文档</title> <style type='text/css'> * { margin: 0; padding: 0; } #left { width: 100px; float: left; background: green; height: 300px; /*overflow: hidden;*/ } #right { width: 100px; float: right; background: red; height: 300px; /*/ overflow: hidden;*/ } #middle { margin-right: 100px; margin-left: 100px; height: 300px; background: #ccc; } </style> </head> <body> <div id="left"> </div> <div id="right"> </div> <div id="middle"> </div> </body> </html>
(2)中间固定(三个float;左右width=50%先用负margin,设置好右边位置,在用内部 不设宽度div magin 确定左边位置)
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style> #left, #right { float: left; margin-left:-271px; width: 50%; } #main { width: 540px; float: left; background: green; } .inner { padding: 20px; } #left .inner, #right .inner { margin-left: 271px; background: orange; } </style> </head> <body> <div id="left"> <div class="inner">this is left sidebar content</div> </div> <div id="main"> <div class="inner">this is main content</div> </div> <div id="right"> <div class="inner">this is right siderbar content</div> </div> </body> </html>
二、相应式布局(重点在CSS3 中的 @media only screen and (min-width:700px){ 再写新样式 })
<!DOCTYPE HTML> <head> <script src="jquery-1.8.2.min.js"></script> <style> * { margin:0; padding:0; } .ul { background-color:rgb(134, 170, 209); height: 55px; } .ul li { float:left; list-style: none; background-color:rgb(134, 170, 209); width: 20%; height: 100%; } .item { display: block; text-align:center; line-height: 49px; height: 100%; transition: all 0.5s; -moz-transition: all 0.5s; /* Firefox 4 */ -webkit-transition: all 0.5s; /* Safari 和 Chrome */ -o-transition: all 0.5s; cursor:pointer; } .item:hover { background-color:rgb(168, 209, 253); } @media only screen and (max-width: 700px) { .ul li { width: 100%; height: 100%; } } </style> <script> </script> </head> <body class="sapUiBody"> <header> <ul class="ul"> <li><a class="item">Home</a></li> <li><a class="item">First</a></li> <li><a class="item">Second</a></li> <li><a class="item">Thirdly</a></li> <li><a class="item">Fourth</a></li> </ul> </header> </body>
三、瀑布流式布局()
<!doctype html> <html> <head> <meta charset="utf-8"> <title>Jquery瀑布流布局(每行代码都有详细注释)-作者:刘晓帆</title> <style type="text/css"> body, ul, li, h3 { margin: 0; padding: 0; list-style: none; font: bold 12px "微软雅黑"; } /*瀑布流布局样式*/ #lxf-box { position: relative; } #lxf-box li { position: absolute; background: #fff; border: solid 1px #ccc; text-align: center; padding: 10px; left: 0px; top: 0; } h3 { padding-top: 8px; } img { width: 200px; height: auto; display: block; border: 0 } /*css3动画*/ li { -webkit-transition: all .7s ease-out .1s; -moz-transition: all .7s ease-out; -o-transition: all .7s ease-out .1s; transition: all .7s ease-out .1s } </style> <script src="../jsForAll/jquery-1.9.1.js" type="text/javascript"></script> </head> <body> <ul id="lxf-box"> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/1.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/2.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/3.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/4.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/5.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/6.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/7.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/8.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/9.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/10.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/9.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/8.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/7.jpg"></a> <h3>图片标题</h3> </li> <li><a href="http://www.liuxiaofan.com/"><img src="../../image/2.jpg"></a> <h3>图片标题</h3> </li> </ul> <script> /* 原理:1.把所有的li的高度值放到数组里面 2.第一行的top都为0 3.计算高度值最小的值是哪个li 4.把接下来的li放到那个li的下面 作者:刘晓帆 博客地址:[url]http://liuxiaofan.com[/url] 编写时间:2012年6月9日 */ var margin = 10;//这里设置间距 var li=$("li");//这里是区块名称 var li_W = li[0].offsetWidth+margin;//取区块的实际宽度(包含间距,这里使用源生的offsetWidth函数,不适用jQuery的width()函数是因为它不能取得实际宽度,例如元素内有pandding就不行了) function liuxiaofan(){//定义成函数便于调用 var h=[];//记录区块高度的数组 var n = document.documentElement.offsetWidth/li_W|0;//窗口的宽度除以区块宽度就是一行能放几个区块 for(var i = 0;i < li.length;i++) {//有多少个li就循环多少次 li_H = li[i].offsetHeight;//获取每个li的高度 if(i < n) {//n是一行最多的li,所以小于n就是第一行了 h[i]=li_H;//把每个li放到数组里面 li.eq(i).css("top",0);//第一行的Li的top值为0 li.eq(i).css("left",i * li_W);//第i个li的左坐标就是i*li的宽度 } else{ min_H =Math.min.apply(null,h) ;//取得数组中的最小值,区块中高度值最小的那个 minKey = getarraykey(h, min_H);//最小的值对应的指针 h[minKey] += li_H+margin ;//加上新高度后更新高度值 li.eq(i).css("top",min_H+margin);//先得到高度最小的Li,然后把接下来的li放到它的下面 li.eq(i).css("left",minKey * li_W); //第i个li的左坐标就是i*li的宽度 } $("h3").eq(i).text("编号:"+i+",高度:"+li_H);//把区块的序号和它的高度值写入对应的区块H3标题里面 } } /* 使用for in运算返回数组中某一值的对应项数(比如算出最小的高度值是数组里面的第几个) */ function getarraykey(s, v) {for(k in s) {if(s[k] == v) {return k;}}} /*这里一定要用onload,因为图片不加载完就不知道高度值*/ window.onload = function() {liuxiaofan();}; /*浏览器窗口改变时也运行函数*/ window.onresize = function() {liuxiaofan();}; </script> </body> </html>
