用javascript实现兼容IE7的类库 IE7_0_9.zip提供下载_javascript技巧

IE7 loads and parses all style sheets into a form that Explorer can understand. You can then use most CSS2/CSS3 selectors without having to resort to CSS hacks.

The lightweight script is a single-line inclusion in your HTML/XML document. No alteration of your original markup is necessary. Neither do you have to alter your CSS.

IE7 provides Microsoft Internet Explorer with support for W3C standard CSS and HTML:

supports the following CSS selectors:
namespace|selector
parent > child
adjacent + sibling
adjacent ~ sibling
[attr], [attr="value"], [attr~="value"] etc
.multiple.classes (fixes bug)
:hover, :active, :focus (for all elements)
:first-child, :last-child, only-child, nth-child, nth-last-child
:check, :disabled, :enabled
:root, :empty, :contains(), :not()
:before/:after/content:
:lang()
