朋友,请帮助我为IE9定义特定的CSS规则?像这样
/* IE 6 fix */ * html .twit-post .delete_note a { background-position-y: 2px; } * html .twit-post .delete_note a:hover { background-position-y: -14px; }
请注意,接受的答案也针对IE10。因此,要获得更完整的列表:
* html .ie6 {property:value;}
要么
.ie6 { _property:value;}
*+html .ie7 {property:value;}
*:first-child+html .ie7 {property:value;}
@media screen\9 { .ie67 {property:value;} }
.ie67 { *property:value;}
.ie67 { #property:value;}
@media \0screen\,screen\9 { .ie678 {property:value;} }
html>/**/body .ie8 {property:value;}
@media \0screen { .ie8 {property:value;} }
.ie8 { property /*\**/: value\9 }
@media screen\0 { .ie8910 {property:value;} }
@media screen and (min-width:0) and (min-resolution: .001dpcm) { // IE9 CSS .ie9{property:value;} }
@media screen and (min-width:0) and (min-resolution: +72dpi) { // IE9+ CSS .ie9up{property:value;} }
@media screen and (min-width:0) { .ie910{property:value;} }
_:-ms-lang(x), .ie10 { property:value\9; }
_:-ms-lang(x), .ie10up { property:value; }
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) { .ie10up{property:value;} }
_:-ms-fullscreen, :root .ie11up { property:value; }
Modernizr在页面加载时快速运行以检测功能。然后使用结果创建一个JavaScript对象,并将类添加到html元素
Javascript:
var b = document.documentElement; b.setAttribute('data-useragent', navigator.userAgent); b.setAttribute('data-platform', navigator.platform ); b.className += ((!!('ontouchstart' in window) || !!('onmsgesturechange' in window))?' touch':'');
在html元素中添加(例如)以下内容:
html
data-useragent='Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C)' data-platform='Win32'
允许目标明确的CSS选择器,例如:
html[data-useragent*='Chrome/13.0'] .nav{ background:url(img/radial_grad.png) center bottom no-repeat; }
如果可能,请避免使用浏览器。识别并解决您发现的所有问题。支持渐进增强和平稳降级 。考虑到这一点,这是在生产环境中并不总是可以实现的“理想世界”场景,因此,以上内容应有助于提供一些不错的选择。
