在當今網頁設計/開發實踐中,使用CSS來為語義化的(X)HTML標記添加樣式風格是重要的關鍵。在設計師們的夢想中都存在著這樣的一個完美世界:所有的瀏覽器都能夠理解和適用多有CSS規則,並且呈現相同的視覺效果(沒有相容性問題)。但是,我們並沒有生活在這個完美的世界,現實中發生的失竊卻總是恰恰相反,很多CSS樣式在不同的瀏覽器中有著不同的解釋和呈現。
當今流行的瀏覽器(如:Firefox、Opera、Internet Explorer、Chrome、Safari等等)中,有一些都是以自己的方式去理解CSS規範,這就會導致有的瀏覽器對CSS的解釋與設計師的CSS定義初衷相衝突,使得網頁的樣子在某些瀏覽器下能正確按照設計師的想法顯示,但有些瀏覽器卻並沒有按照設計師想要的樣子顯示出來,這就導致瀏覽器的相容性問題。更糟的是,有的瀏覽器完全無視CSS的一些聲明和屬性。
正因為上述衝突和問題依然存在於這個”不完美的世界”,所以一些設計師想到了一種避免瀏覽器安全色性問題的方法,那就是CSS Reset,什麼是CSS Reset?我們可以把它叫做CSS重設,也有人叫做CSS複位、預設CSS、CSS重設等。CSS重設就是由於各種瀏覽器解釋CSS樣式的初始值有所不同,導致設計師在沒有定義某個CSS屬性時,不同的瀏覽器會按照自己的預設值來為沒有定義的樣式賦值,所以我們要先定義好一些CSS樣式,來讓所有瀏覽器都按照同樣的規則解釋CSS,這樣就能避免發生這種問題。
一.最簡化的CSS Reset(重設) :
* {
padding: 0;
margin: 0;
}
這是最普遍最簡單的CSS重設,將所有元素的padding和margin值都設為0,可以避免一些瀏覽器在理解這兩個屬性預設值上的”分歧”。
* {
padding: 0;
margin: 0;
border: 0;
}
這是在上一個重設的基礎上添加了對border屬性的重設,初始值為0的確能避免一些問題。
* {
outline: 0;
padding: 0;
margin: 0;
border: 0;
}
在前兩個的基礎上添加了outline屬性的重設,防止一些衝突。
二.濃縮實用型CSS Reset(重設):
* {
vertical-align: baseline;
font-weight: inherit;
font-family: inherit;
font-style: inherit;
font-size: 100%;
outline: 0;
padding: 0;
margin: 0;
border: 0;
}
該CSS重設方法出自Perishable Press,這是他常用的方法。
三.Poor Man 的CSS Reset:
html, body {
padding: 0;
margin: 0;
}
html {
font-size:1em;
}
body {
font-size:100%;
}
a img, :link img, :visited img {
border:0px;
}
這個重設方法將html和body下元素的padding和margin都設為0,並分別為html標籤和body標籤下的所有元素設定了初始的字型大小,最重要的是把有連結的圖片的預設邊框去掉了。

好了,CSS重設目前先總結到這裡,這15套重設方法其實都是有共同點的,也許有的實現方法不同,但大部分都是同一個目的,就是為了讓更多的瀏覽器能顯示同樣的效果。有了這些CSS重設作為資料和參考,也許會對你的工作有所協助甚至提高效率,但是,畢竟這些重設都是別人寫的,你完全也可以為自己量身定製一套CSS重設。
