區別IE6與FF:
background:orange;*background:blue;
區別IE6與IE7:
background:green !important;background:blue;
區別IE7與FF:
background:orange; *background:green;
區別FF,IE7,IE6:
background:orange;*background:green !important;*background:blue;
註:IE都能識別*;標準瀏覽器(如FF)不能識別*;
IE6能識別*,但不能識別 !important,
IE7能識別*,也能識別!important;
FF不能識別*,但能識別!important;
IE6 IE7 FF
* √ √ ×
!important × √ √
--------------------------------------------------------------------------------
另外再補充一個,底線"_",
IE6支援底線,IE7和firefox均不支援底線。

於是大家還可以這樣來區分IE6,IE7,firefox
: background:orange;*background:green;_background:blue;

註:不管是什麼方法,書寫的順序都是firefox的寫在前面,IE7的寫在中間,IE6的寫在最後面。
