!important的用法和在IE6下的表现:
!important可以提高指定CSS语句的优先级，使用方法是在相应的CSS语句后面加上!important。例如:

    蚂蚁部落

 
蚂蚁部落
Copy after login

大家都知道CSS样式具有“就近原则”，也就是后面定义的样式能够覆盖前面的样式，以上代码中如果不使用!important，那么字体颜色呈现红色。
当前所有的主流浏览器都支持!important，但是IE6上不能完全支持，为什么说是不能够完全支持，因为在有些情况支持，有些情况不支持，例如上面的代码中，IE6浏览器就不支持，文字将以红色字体呈现，再来看下面这么一个例子:

    蚂蚁部落

蚂蚁部落
Copy after login

以上代码中，大家可以看到字体颜色呈蓝色显示，这说明如果两段代码在同一个大括号({})中使用，IE6下就不起做，如果分开在两个大括号（{}）中使用就会有作用。
