HTML使用DIV+CSS如何实现左边导航，右边显示内容，点击那个导航显示那个内容 5
1、新建html文档。

<li><A href="#">前端交流</A></li>
<li><A href="#">团队生活</A></li>
<div id="lanPos"></div>
</ul>
3、书写css代码。
<style>
html, body, div, span, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, abbr, address, cite, code, del, dfn, em, img, ins, kbd, q, samp, small, strong, sub, sup, var, b, i, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, figcaption, figure, footer, header, hgroup, menu, nav, section, summary, time, mark, audio, video { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; font-weight: normal; }
body { line-height: 1; }
:focus { outline: 1; }
article, aside, canvas, details, figcaption, figure, footer, header, hgroup, menu, nav, section, summary { display: block; }
nav ul, ul, li { list-style: none; }
blockquote, q { quotes: none; }
blockquote:before, blockquote:after, q:before, q:after { content: ''; content: none; }
a { margin: 0; padding: 0; border: 0; font-size: 100%; vertical-align: baseline; background: transparent; text-decoration: none; }
a:hover { text-decoration: underline; }
ins { background-color: #ff9; color: #000; text-decoration: none; }
mark { background-color: #ff9; color: #000; font-style: italic; font-weight: bold; }
del { text-decoration: line-through; }
abbr[title], dfn[title] { border-bottom: 1px dotted #000; cursor: help; }
table { border-collapse: collapse; border-spacing: 0; }
hr { display: block; height: 1px; border: 0; border-top: 1px solid #cccccc; margin: 1em 0; padding: 0; }
input, select { vertical-align: middle; }
.fl { float: left; display: inline-block; }
.fr { float: right; display: inline-block; }
.clearfix:after { visibility: hidden; display: block; font-size: 0; content: " "; clear: both; height: 0; }
.clearfix { display: inline-table; }
* html .clearfix { height: 1%; }
.clearfix { display: block; }
html { font-size: 62.5%; /* 10÷16=62.5% */ }
body { font-size: 12px; font-size: 1.2rem; background: #F8F8F8; font-family: "宋体"; }
ul { width: 180px; margin: 0 auto; background: #fff; position: relative; z-index: 0; padding: 60px 20px 70px; }
ul li { height: 40px; line-height: 40px; text-align: center; border-bottom: 1px solid #F8F8F8; }
ul li a { color: #666; display: block; }
ul li a:hover { color: #FF5F3E; text-decoration: none; }
ul li a.hover { color: #FF5F3E; }
#lanPos { width: 225px; height: 40px; line-height: 40px; background: #F8F8F8; border-left: 5px solid #FF5F3E; position: absolute; left: -5px; top: 0; z-index: -1; transition: top .2s; }
</style>
4、书写并引用js代码。
<script src="js/jquery.min.js"></script>
<script>
$(function(){
$('#lanPos').css('top',$('.hover').offset().top);
$('ul li').hover(function(){
$('#lanPos').css('top',$(this).offset().top);
},function(){
$('#lanPos').css('top',$('.hover').offset().top);
})
$('ul li').click(function(){
for(var i=0;i<$('ul li').size();i++){
if(this==$('ul li').get(i)){
$('ul li').eq(i).children('a').addClass('hover');
}else{
$('ul li').eq(i).children('a').removeClass('hover');
}
}
})
})
</script>
5、代码整体结构。
