核心提示：CSS技巧：關於CSS Hack與float閉合
一、CSS HACK
以下兩種方法幾乎能解決現今所有HACK.
1, !important
隨著IE7對!important的支援, !important 方法現在只針對IE6的HACK.(注意寫法.記得該聲明位置需要提前.)
<style>#wrapper{width: 100px!important;width: 80px;}</style></p><P>
2, IE6/IE77對FireFox
*+html 與 *html 是IE特有的標籤, firefox 暫不支援.而*+html 又為 IE7特有標籤.
<style><br/>#wrapper<br/>{<br/>#wrapper { width: 120px; }<br/>*html #wrapper { width: 80px;}<br/>*+html #wrapper { width: 60px;}<br/>}<br/></style><br/>
注意:
*+html 對IE7的HACK 必須保證HTML頂部有如下聲明：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">
二、float 閉合（清除浮動）
將以下代碼加入Global CSS 中,給需要閉合的div加上 class="clearfix" 即可,屢試不爽.
<style><br/>.clearfix:after<br/>{<br/>content:".";<br/>display:block;<br/>height:0;<br/>clear:both;<br/>visibility:hidden;<br/>}<br/>.clearfix<br/>{<br/>display:inline-block;<br/>}<br/>.clearfix {display:block;}<br/></style><br/>
