你們平時看得多的應該是IE瀏覽器的hack寫法比較多，但對於現代瀏覽器，好比說Safari、Chrome、Firefox等瀏覽器的hack寫法並很少見，甚至有的不知道怎麼寫。若是您是屬於後者，根本不知道各瀏覽器下具備哪些hack手段，不要着急。由於Hugo Giraudel和Tim Pietrusky將各瀏覽器下的hack寫整理放在了Browserhacks.com之上。

1、Chrome瀏覽器

選擇器Hack

/* Chrome 24- and Safari 5- */
::made-up-pseudo-element, .selector { 代碼放在這裏 } 

媒體查詢Hacks

/* Chrome, Safari 3+ */
@media screen and (-webkit-min-device-pixel-ratio:0) { 代碼放在這裏 } 

JavaScript Hack

/* Chrome */
var isChrome = Boolean(window.chrome); 

2、Firefox瀏覽器

屬性選擇器Hack

/* Firefox 1.5 */
body:empty .selector { 樣式代碼放這裏 } /* Firefox 2+ */ .selector, x:-moz-any-link { 樣式代碼放這裏 } /* Firefox 3+ */ .selector, x:-moz-any-link; x:default { 樣式代碼放這裏 } /* Firefox 3.5+ */ body:not(:-moz-handler-blocked) .selector { 樣式代碼放這裏 }

媒體查詢Hack

/* Opera 7 */ @media all and (min-width: 0px){ 樣式代碼放這裏 } /* Opera 12- */ @media all and (-webkit-min-device-pixel-ratio:10000), not all and (-webkit-min-device-pixel-ratio:0) { 樣式代碼放這裏 } /* Opera, Firefox 3.5+, IE 9/10 */ @media screen and (min-resolution: +72dpi) { 樣式代碼放這裏 } /* Opera, IE 8/9/10 */ @media screen { 樣式代碼放這裏 }

上面列出各個瀏覽器下hack的寫法，固然在實際運用之中並不建議使用hack。若是你的頁面須要hack來處理時，請先檢查你的css或者js，若是實在沒法達到要求，在考慮使用hack來處理。
