CSS3.info 這個網站提供了一個網頁來測試瀏覽器對 CSS 3 selectors
的支援。(但這個測試不包含 :hover, :active, :focus and :selection
這幾個需要與使用者互動才能測試的 selectors。)

我測試過的結果如下：

• IE 6 (Maxthon 2) on Windows XP
  From the 43 selectors 10 have passed, 1 are buggy and 32 are unsupported (Passed 276 out of 578 tests)
  
• Firefox 2.0.0.5 on Fedora 7
  From the 43 selectors, 26 have passed, 10 are buggy and 7 are unsupported (Passed 357 out of 578 tests)
  
• Firefox 2.0.0.6 on Windows XP
  From the 43 selectors 26 have passed, 10 are buggy and 7 are unsupported (Passed 359 out of 578 tests)
  
• Firefox 2.0.0.6 on Windows XP with Text Shadow installed
  From the 43 selectors 30 have passed, 6 are buggy and 7 are unsupported (Passed 361 out of 578 tests)
  
• Minfield 3.0a8pre on Windows XP
  From the 43 selectors 32 have passed, 4 are buggy and 7 are unsupported (Passed 369 out of 578 tests)
  
• Minefield 3.0b4pre (2008020704) (on Debian 4)
  From the 43 selectors 30 have passed, 4 are buggy and 9 are unsupported (Passed 367 out of 578 tests)
  
• Epiphany 2.14.3 (on Debian 4 testing)
  From the 43 selectors 26 have passed, 10 are buggy and 7 are unsupported (Passed 357 out of 578 tests)
  
• Safari 3.0.3 (522.15.5) beta on Windows XP
  From the 43 selectors 25 have passed, 9 are buggy and 9 are unsupported
  (Passed 346 out of 578 tests)
  
• Konqueror 3.5.7-0.1.fc7 Fedora on Fedora 7
  From the 43 selectors 43 have passed, 0 are buggy and 0 are unsupported
  (Passed 578 out of 578 tests)
  Konqueror Rocks!
  
• Opera 9.22 on Windows XP
  From the 43 selectors 25 have passed, 3 are buggy and 15 are unsupported (Passed 346 out of 578 tests)
  
  據說 Opera 9.5 已大幅改善對 CSS3 的相容性，已通過這個 CSS3
  的所有測試，Opera Rocks!
  http://www.css3.info/opera-95-races-ahe ... 3-support/

不管如何，要記得一件事，這只是對 selectors 的測試，僅僅是 CSS3
其中一部分的測試，並不能代表以上瀏覽器對 CSS3 的支援程度。

IE7 小弟沒裝，等網友補充吧～

Konqueror好威!XD

IE7( on Windows Vista ):
From the 43 selectors 13 have passed, 4 are buggy and 26 are unsupported (Passed 330 out of 578 tests)

因為KHTML是首個完全通過Acid2測試的引擎啦

但是ACID2並不包含CSS3的測試吧?
而且由KHTML改來的WebKit也沒有做到那個程度

話說... Fx 3 從 Gran Paradiso Alpha 1 之後
也已經通過 acid2 了
真是高興！

我測試Firefox 2.0.0.6在Ubuntu Linux 7.10上是這樣
From the 43 selectors 26 have passed, 10 are buggy and 7 are unsupported (Passed 357 out of 578 tests)

到單位後再測試Firefox 3的成績

KHTML是第2個，第一個是WebCore。
Konqueror本來就很厲害了，只是在這環境下即使再標準再優秀，得不到Google和Yahoo!這些大廠的支援還是沒用的……
P.S.之前就聽過Konqueror部份支援CSS3了。

不過Safari不支援很奇怪，WebCore不是KHTML改良版？怎麼反而有問題？希望KHTML併入WebCore以後Apple能好好對待它，一定要像KDE團隊那樣用心的在這個引擎上。

重點似乎不同
KHTML在遇到不知名tag(比方說<ruby>)時,CSS完全不能作用

Apple在我看來還要再多努力
我有點受不了Safari 2的BUG....

雖然這不是錯，但卻證實了KHTML容錯率很低……
