我正在使用的網頁在除IE以外的其他瀏覽器中工作正常。我正在使用IE 10(預覽版),所以我可以使用陰影,而<br />
不工作,所以我做了一個特定於IE的css,這樣如果瀏覽器是IE,它就會加載IE的CSS。那麼,當我去改變.homepagetable的頁邊距時,它也會將CSS應用到其他瀏覽器。 main.css和all-ie-only.css之間的區別是.homepagetable。僅限IE瀏覽器的CSS隻影響IE中的頁面,而不影響其他瀏覽器

警告:您的代碼非常容易受到SQL注入攻擊,並且存在許多其他明顯的安全漏洞。另外,請注意'mysql_xxx()'函數已被棄用;建議改爲更新的'mysqli'或'PDO'庫。 – SDC 2013-02-25 14:26:54
我還沒有寫完,它只是我的高級項目。我正在建立一個社交網絡,它只是成爲一種產品,並且可能不會在互聯網上使用,除了一天之內沒有任何重要的東西被存儲。 @SDC – 2013-02-25 14:38:07
你是否使用了「ie-only樣式表」?那裏有很多。此外,只是一個提示:你不需要重複所有其他的東西。你可以有一個主樣式表,然後一個用於IE的僅覆蓋需要的內容 – naomi 2013-02-25 14:45:57
