在當(dāng)今網(wǎng)頁設(shè)計(jì)/開發(fā)實(shí)踐中颅围,使用CSS來為語義化的(X)HTML標(biāo)記添加樣式風(fēng)格是重要的關(guān)鍵志鞍。在設(shè)計(jì)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(guī)則,并且呈現(xiàn)相同的視覺效果(沒有兼容性問題)痹换。但是征字,我們并沒有生活在這個完美的世界,現(xiàn)實(shí)中發(fā)生的失竊卻總是恰恰相反娇豫,很多CSS樣式在不同的瀏覽器中有著不同的解釋和呈現(xiàn)匙姜。
當(dāng)今流行的瀏覽器(如:Firefox、Opera冯痢、Internet Explorer氮昧、Chrome、Safari等等)中浦楣,有一些都是以自己的方式去理解CSS規(guī)范袖肥,這就會導(dǎo)致有的瀏覽器對CSS的解釋與設(shè)計(jì)師的CSS定義初衷相沖突,使得網(wǎng)頁的樣子在某些瀏覽器下能正確按照設(shè)計(jì)師的想法顯示振劳,但有些瀏覽器卻并沒有按照設(shè)計(jì)師想要的樣子顯示出來昭伸,這就導(dǎo)致瀏覽器的兼容性問題。更糟的是澎迎,有的瀏覽器完全無視CSS的一些聲明和屬性庐杨。
正因?yàn)樯鲜鰶_突和問題依然存在于這個”不完美的世界”,所以一些設(shè)計(jì)師想到了一種避免瀏覽器兼容性問題的方法夹供,那就是CSS Reset灵份,什么是CSS Reset?我們可以把它叫做CSS重設(shè)哮洽,也有人叫做CSS復(fù)位填渠、默認(rèn)CSS、CSS重置等鸟辅。CSS重設(shè)就是由于各種瀏覽器解釋CSS樣式的初始值有所不同氛什,導(dǎo)致設(shè)計(jì)師在沒有定義某個CSS屬性時,不同的瀏覽器會按照自己的默認(rèn)值來為沒有定義的樣式賦值匪凉,所以我們要先定義好一些CSS樣式枪眉,來讓所有瀏覽器都按照同樣的規(guī)則解釋CSS,這樣就能避免發(fā)生這種問題再层。
今天總結(jié)收集了15套CSS重設(shè)實(shí)例贸铜,您可以在前端開發(fā)工作中進(jìn)行參考和使用,有些是很簡化的CSS Reset聂受,有些則是非常復(fù)雜非常全面的CSS Reset蒿秦,至于使用哪套,全看您的愛好或需要蛋济。
一.最簡化的CSS Reset(重設(shè)) :
* {
padding: 0;
margin: 0;
}
這是最普遍最簡單的CSS重設(shè)棍鳖,將所有元素的padding和margin值都設(shè)為0,可以避免一些瀏覽器在理解這兩個屬性默認(rèn)值上的”分歧”碗旅。
* {
padding: 0;
margin: 0;
border: 0;
}
這是在上一個重設(shè)的基礎(chǔ)上添加了對border屬性的重設(shè)渡处,初始值為0的確能避免一些問題镜悉。
* {
outline: 0;
padding: 0;
margin: 0;
border: 0;
}
在前兩個的基礎(chǔ)上添加了outline屬性的重設(shè),防止一些沖突骂蓖。
二.濃縮實(shí)用型CSS Reset(重設(shè)):
* {
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(shè)方法出自Perishable Press,這是他常用的方法川尖。
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(shè)方法將html和body下元素的padding和margin都設(shè)為0登下,并分別為html標(biāo)簽和body標(biāo)簽下的所有元素設(shè)置了初始的字體大小,最重要的是把有鏈接的圖片的默認(rèn)邊框去掉了叮喳。

好了被芳,CSS重設(shè)目前先總結(jié)到這里,這15套重設(shè)方法其實(shí)都是有共同點(diǎn)的馍悟,也許有的實(shí)現(xiàn)方法不同畔濒,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锣咒。有了這些CSS重設(shè)作為資料和參考侵状,也許會對你的工作有所幫助甚至提高效率,但是毅整,畢竟這些重設(shè)都是別人寫的趣兄,你完全也可以為自己量身定制一套CSS重設(shè)。
