浏览器的CSS Hack方法汇总

CSS hacks利用浏览器的漏洞来隐藏特定浏览器的CSS规则。实现浏览器兼容主要有两种方式条件样式表和CSS Hacks（Selector Hacks、Attribute Hacks）。对此根据一些资料汇总了一些CSS Hacks方法。

浏览器特定的CSS Hacks综合列表：

67:
68: /* IE6 */
69: #once { _color: blue }
70:

73:
74: /* Everything but IE6 */
75: #diecisiete { color/**/: blue }

82:
83: /* IE6, IE7 -- acts as an !important */
84: #veintesiete { color: blue !ie; } /* string after ! can be anything */
85:
86: /* IE8, IE9 */
87: #anotherone {color: blue\0/;} /* must go at the END of all rules */
88:
89: /* IE9, IE10 */
90: @media screen and (min-width:0\0) {
91: #veintidos { color: red}
92: }

细说Hacks:

1.条件样式表

像这样的代码你应该见过:

PS：yahoo的内部编码最佳做法并不建议使用有条件的样式表。它会增加额外的平均1或2个HTTP下载请求（参考这里）。

2.选择器Hacks（Selector Hacks）
