添加有效的doctype修復了這個IE8的，例如：

<!DOCTYPE html>

Oterwise IE將被渲染Quirks mode和頁面的CSS child selectorul#mrmenu li:hover>.submenu你用來顯示菜單將不起作用。 注意：CSS後代選擇器仍然可以在怪癖模式下工作。

附件是嵌入式CSS的獨立HTML文件，在IE8中可以進行少量編輯，但當合併到較大的WordPress網站時，它將無法工作。這是爲了修復實際的WordPress的網站，而不是HTML文件 - 但你可以看看一個想法。這裏的網站[鏈接]（http://trondheim360.com） – 2013-04-09 10:07:24

該網站鏈接在IE8中爲我工作。加載後網站似乎凍結（很可能是我的防火牆），但瀏覽器再次變得響應後，頂層菜單懸停正在運行。稍後，我可以稍後從防火牆外的另一臺計算機上嘗試。 – andyb 2013-04-09 10:19:48
