When ie7 does not recognize !important [Layout solution]_Experience exchange

May 16, 2016 pm 12:09 PM

在IE7之前,我們在佈局時常用!important來解決IE和FF之間的差別; 但是在IE7出來之後,!important對IE7就不起作用了,而有些時候IE7的解釋方法又與FF和IE6不同;這時新的問題就出現了;用!important可以解決IE6但是解決不了IE7; 這樣在不同的瀏覽器中看到的同一個網頁的效果就不同了;

這是前天作版面時的一個問題;可以先看一下效果;http://www.zishu.cn/blogview.asp?logID=553 

或是運行下邊的程式碼也可以同樣看到效果:

複製程式碼 程式碼如下:





zishu.cn test




  

        
  • 64d / 47 hitspixu

  •     
  • 24d / 35 hits秀才

  •     
  • 66d / 87 hits透露

  •     
  • 40d / 34 hitsLIVID

  •     
  • 47d / 56 hits老孟

  •     
  • 42d / 36hits小玉

  •     
  • 63d / 67 hitspixu

  •   





在這個例子中,如果我把
 程式碼
*+html #zishu_test li a:hover span {margin-left:-8px; }/* IE7*/ 
這行刪除;那麼在IE7中;就會有差別了;

為了解決這個問題,我看了;http://www.blueidea.com/tech/site/2006/3626.asp 裡邊的一種方法; 但是如果程式設計師和佈局人不是同一個人的話;這樣的方法很不好控制; 於是才有了下邊的方法;

以下是程式碼; 
 程式碼
複製程式碼 程式碼如下:

* html #zishu_test  a:hover ginsppanft; /* IE6 */  
*+html #zishu_test li a:hover span {margin-left:-8px; }/* IE7*/  
「*+html」被ie7與ie5.01所使用,而區分ie7與ie5.01又有很簡單的方法,便是important,把important寫在前面,這樣才能形成了單獨針對ie7 hack的方法了。

例如:

*+html div.IE7 { 
width:200px; !important; 
width:100px
};

I'd say "website" fits better than "mobile app" but I like this framing from Max Lynch:
