IE6 解決方法


body {
 _behavior: url("csshover3.htc");/*---ie6支援hover--加入body---*/
}

 

 

*註解：
關於CSS鏈結_behavior上增加(" ")這兩個符號解釋為url("csshover3.htc"); ----表示csshover3.htc在此網頁資料夾上。然而一般使用的是url(#);才是所謂的依照檔案位址指定路徑。

例如：有個圖片檔名為img.jpg要設定為body的背景。

  body{
           backgroud-img: url(/ucamc/..images/img.jpg);
           } /*----此img.jpg在外面的images資料夾裡。----*/ 

我測試使用("")兩個符號，設定圖片背景img.jpg
 
 body{
           backgroud-img: url("/ucamc/img.jpg");
           } /*-----------是沒有反應的----------*/ 
所以結論為，url("#") 只能設定使用_behavior載入在此網頁本身資料夾上。

相關資料夾路徑設定方法有：
 
  [ / ]：下層資料夾 (/imges/img.jpg)
  [../ ]：上層資料夾(../imges/img.jpg)
 
相信這樣解釋大家能夠了解，csshover將要放在哪裡做連結，比較不會混淆，而達不到功效。
