網絡上關於CSS重置的代碼很是多。本段代碼是根據Eric Meyer’s reset codes進行改編的,裏面包含一點響應式圖片和全部核心元素的邊界框設置,這樣就能夠保持頁邊距和填充能夠很好地對齊。

2.經典的CSS Clearfixhtml
這個clearfix代碼已在Web開發者之間普遍流傳,這段類選擇器要應用到持有浮動元素的容器中,確保後面的內容都不會浮動,但會被下推和清除。web

html[xmlns] .clearfix {

; }
* html .clearfix {
height

; }

在表現上,新版本和經典版本不存在什麼差別,這些類能夠有效地清除全部floats,但它們只兼容現代瀏覽器和傳統的IE 6-8。

;
display

.clearfix:after {
clear
:
both
; }
/* IE 6/7 */
.clearfix { zoom:

; }
|
CSS3裏的許多屬性都與瀏覽器相兼容,但也有特例,好比opacity,須要對它進行一些更新才能夠。附加過濾屬性能夠兼容任何老版的IE瀏覽器。

這段代碼主要用在頁面上進行分離引用或複製內容,而且給頁面文字提供了默認樣式。

這是一段很是好的模板,用於各類零零碎碎的媒體查詢,在移動設備上也可使用,這段代碼甚至能夠經過使用min-device-pixel-ratio引用到視網膜設備上。
