IE下Css圆角没有的解决方法

在网頁制作时，圆角的样式在很多时候都要到，大多数都是用图片来搞，其实图片不图片无所谓的，但也有的朋友比较喜欢用CSS来写，CSS写的话在火狐、谷歌等浏览器都是没有问题的。但是在IE下就会出现问题，圆角就没有了。这时候就要用到一个文件，当时那个文件是哪里下的已经记不清了，但用着还是挺不错的。由于不知道怎么上传文件，就只能把源码弄出来了。 test.html 复制代码代码如下: html headtitletest/title style type='text/css' .test { width:100px; height:100px; background-color: blue; margin-bottom:10px; border-radius: 10px; behavior: url(ie-css3.htc); } /style /head body div test /div /body /html ie-css3.htc 复制代码代码如下: --Do not remove this if you are using-- Original Author: Remiz Rahnas Original Author URL: http://www.htmlremix.com Published date: 2008/09/24 Changes by Nick Fetchak: - IE8 standards mode compatibility - VML elements now positioned behind original box rather than inside of it - should be less prone to breakage - Added partial support for ’box-shadow’ style - Checks for VML support before doing anything - Updates VML element size and position via timer and also via window resize event - lots of other small things Published date : 2010/03/14 http://fetchak.com/ie-css3 Thanks to TheBrightLines.com (http://www.thebrightlines.com/2009/12/03/using-ies-filter-in-a-cross-browser-way) for enlightening me about the DropShadow filter public:attach event='ondocumentready' onevent='ondocumentready(’v08vnSVo78t4JfjH’)' / script type='text/javascript' timer_length = 200; // Milliseconds border_opacity = false; // Use opacity on borders of rounded-corner elements?
