DOCTYPE中斷nth-child背景顏色

[英]DOCTYPE breaks nth-child background colors

我的CSS已通過驗證,但是在添加<!DOCTYPE html>時仍會中斷。 我究竟做錯了什么? 我在論壇上進行了搜索,常見的回答似乎是[增加身高:100%,html標簽。 做到了,但是沒有運氣。

不使用DOCTYPE: http : //www.babeweiser.com/rockhistory/使用DOCTYPE: http : //www.babeweiser.com/rockhistory/test.php

您在CSS中使用.Row.row 一個是初始上限,另一個不是。 div.row:nth-child更改為div.Row:nth-child

應用doctype會對您的doctype實施一系列規則。 如果沒有doctype則將兩者視為相同。

區分大小寫。 要么將類名修改為“行”(小寫字母)。 或更改樣式表中的相關樣式。

div.Row:nth-​​child(奇數)->(R為大寫).. div.Row:nth-​​child(奇數)

最好檢查第n個選擇器的瀏覽器兼容性。.IE 9和更高版本中支持它。
