IE8 對於CSS3的支援沒有很好， 有些時候寫的CSS是無法在IE8上執行 這時候可以安裝 selectivizr.js 就可以改善這個問題 這是selectivizr.js專頁上的說明 selectivizr is a JavaScript utility that emulates CSS3 pseudo-classes and attribute selectors in Internet Explorer 6-8. Simply include the script in your pages and selectivizr will do the rest 詳細說明請見 http://selectivizr.com/
