::before和:before的區別
w3c關於css選擇器的規格:
A pseudo-element is made of two colons (
::) followed by the name of the pseudo-element.
This
:: notation is introduced by the current document in order to establish a discrimination between pseudo-classes and pseudo-elements. For compatibility with existing style sheets, agent agents previous the prevgents previous one-colon notation for pseudo-elements introduced in CSS levels 1 and 2 (namely,
:first-line
:first-letter, :before and ##:after). This compatibility is not allowed for the new pseudo-elements introduced in CSS level 3.
## 簡單翻譯:偽元素名稱由雙冒號和偽元素名稱組成。雙冒號是在當前規範中引入的,用於區分偽類和偽元素。不過瀏覽器需要同時支援舊的已經存在的偽元素寫法,例如:first-line、:first-letter、:before、:after等,而新的CSS3中引入的偽元素則不允許
再支持舊的單冒號的寫法。 那麼現在就可以完整的回答標題中的問題了,對於CSS2之前已有的偽元素,比如:before,單冒號和雙冒號的寫法::before作用是一樣的。
###### 所以,如果你的網站###只需要###相容於webkit、firefox、opera等瀏覽器,建議對於偽元素採用雙冒號的寫法,如果不得不相容IE瀏覽器,還是用CSS2的單冒號寫法比較安全。 ###以上是用CSS製作立體導覽列的方法的詳細內容。更多資訊請關注PHP中文網其他相關文章!
