CSS hack: differentiate IE6, IE7, IE8, and Firefox

selector {
property: value; /* all browsers */
property: value \ 9;/* all IE browsers */
+ property: value;/* IE7 */
_ property: value;/* IE6 */
}

Of course, pay attention to the sequence. Based on the priority of CSS, the preceding statements show values for Firefox, IE8, IE7, and IE6 respectively.

<P class = "ie">
<Span style = "display: block; display: None \ 9;"> Hey, I used Firefox and blue. </Span>
<! -- [If IE 8]> pretty good, very advanced. Use IE8! The text is brown. <! [Endif] -->
<! -- [If IE 7]> you, IE7, red text! <! [Endif] -->
<! -- [If IE 6]> although green text is displayed, IE6 is not a good thing! <! [Endif] -->
</P>

Yes, it is the result of IE condition annotation + CSS. Let's take a look at the IE condition comments.
