SEO优化：DIV+CSS优化技巧(一)
1.控制横向和纵向滚动条的显隐？
<body style="overflow-y:hidden"> 去掉x轴
<body style="overflow-x:hidden"> 去掉y轴
<body scroll="no">不显
________________________________________
2.表格变色
<td onmouseover="this.style.backgroundColor='#FFFFFF'"
onmouseout="this.style.backgroundColor=''"
style="CURSOR: hand">
________________________________________
3.禁止复制，鼠标拖动选取
<body ondragstart=window.event.returnValue=false oncontextmenu=window.event.returnValue=false onselectstart=event.returnValue=false>
________________________________________
4.普通iframe页面
<iframe name="name" src="main.htm" width="450" height="287" scrolling="Auto" frameborder="0"></iframe>
________________________________________
5.iframe自适应高度
<iframe name="pindex" src="index.asp" frameborder=false scrolling="auto" width="100%" height="100%" frameborder=no onload="document.all['pindex'].style.height=pindex.document.body.scrollHeight" ></iframe>
________________________________________
6.IE地址栏前换成自己的图标&可以在收藏夹中显示出你的图标
<link rel="Shortcut Icon" href="favicon.ico">
<link rel="Bookmark" href="favicon.ico">
________________________________________
7.字号缩放
越来越多的人长时间的泡网，眼镜的普及率也越来越高，让文字大点，让更多的用户看的更清楚。
<script type="text/javascript">
function doZoom(size)
{document.getElementById('zoom').style.fontSize=size+'px';}
</script>
<span id="zoom">需要指定大小的文字</span>
<a href="javascript:doZoom(16)">大</a> <a href="javascript:doZoom(14)">中</a> <a href="javascript:doZoom(12)">小</a>
________________________________________
8.简单的跳转网页代码
如果你要让页面显示3秒钟之后跳转，可以在html代码的<head></head>部分加上这样的代码：
<meta http-equiv="refresh" content="3; url=http://www.webkkk.com">
________________________________________
9.iframe(嵌入式帧)自适应高度
填写的嵌入地址一定要和本页面在同一个站点上，否则会提示“拒绝访问！”。对跨域引用有权限问题，请查阅其他资料。
<iframe name="guestbook" src="gbook/index.asp" scrolling=no width="100%" height="100%" frameborder=no onload="document.all['guestbook'].style.height=guestbook.document.body.scrollHeight"></iframe>
________________________________________
10.跳转菜单新窗口
<select name="select" onchange="window.open(this.options[this.selectedIndex].value)">
<option value="http://www.microsoft.com/ie"> Internet Explorer</option>
<option value="http://www.microsoft.com"> Microsoft Home</option>
<option value="http://msdn.microsoft.com"> Developer Network</option>
</select>
________________________________________
11.flash透明选项
<param name="wmode" value="transparent">
________________________________________
12.添加到收藏夹和设为首页
<a href=# onclick="this.style.behavior='url(#default#homepage)';this.setHomePage('http://www.makewing.com/lanren/');">设为首页</a>
<a href="javascript:window.external.AddFavorite('http://www.makewing.com/lanren/','站长设计网')">收藏本站</a>
________________________________________
13.记录并显示网页的最后修改时间
<script language=JavaScript>
document.write("最后更新时间: " + document.lastModified + "")
</script>
________________________________________
14.节日倒计时
<Script Language="JavaScript">
var timedate= new Date("October 1,2002");
var times= "国庆节";
var now = new Date();
var date = timedate.getTime() - now.getTime();
var time = Math.floor(date / (1000 * 60 * 60 * 24));
if (time >= 0)
document.write( "现在离"+times+"还有: "+time +"天")
</Script>
________________________________________
15.加在HEAD里
禁止缓存
<meta http-equiv="Expires" CONTENT="0">
<meta http-equiv="Cache-Control" CONTENT="no-cache">
<meta http-equiv="Pragma" CONTENT="no-cache">
________________________________________
16.让IFRAME框架内的文档的背景透明
<iframe src="about:<body style='background:transparent'>" allowtransparency></iframe>
________________________________________
17.打开窗口即最大化
<script language="JavaScript">
<!-- Begin
self.moveTo(0,0)
self.resizeTo(screen.availWidth,screen.availHeight)
// End -->
</script>
________________________________________
18.加入背景音乐
<bgsound src="mid/windblue[1].mid" loop="-1"> 只适用于IE
<embed src="music.mid" autostart="true" loop="true" hidden="true"> 对Netscape ,IE 都适用
________________________________________
19.滚动
<marquee direction=up height=146 onmouseout=start() onmouseover=stop() scrollAmount=2>滚动信息
</marquee>
________________________________________
20.防止点击空链接时，页面往往重置到页首端
代码“javascript:void(null)”代替原来的“#”标记
________________________________________
21.文字或图片弹出指定大小的窗口
在body中加入
<script language="JavaScript" type="text/JavaScript">
function MM_openBrWindow(theURL,winName,features) {window.open(theURL,winName,features);}
</script>
弹出代码
<a href="#" target="_self" onClick="MM_openBrWindow('windows01.htm','','width=550,height=380')" width="550" height="380" border="0">图片或文字</a>
________________________________________
22.跳转页面代码
<meta http-equiv="refresh" content="5;url=http://www.makewing.com">
________________________________________
23.细线分隔线
<hr noshade size=0 color=#C0C0C0>
________________________________________
24.网页中的自动换行
<td style="word-break:break-all">就搞定了。
完整的是
style="table-layout: fixed;WORD-BREAK: break-all; WORD-WRAP: break-word"
________________________________________
25.消除ie6自动出现的图像工具栏，设置 GALLERYIMG属性为false或no .
<IMG SRC="mypicture.jpg" HEIGHT="100px" WIDTH="100px" GALLERYIMG="no">
________________________________________
26.禁止页面正文内容被选取
<body oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return
false"onmouseup="document.selection.empty()">
________________________________________
27.不能点右键，不用CTRL+A，不能复制作!
<body oncontextmenu="window.event.returnValue=false"
onkeypress="window.event.returnValue=false"
onkeydown="window.event.returnValue=false"
onkeyup="window.event.returnValue=false"
ondragstart="window.event.returnValue=false"
onselectstart="event.returnValue=false">
</body>
