CSS Hacks for Internet Explorer 8

Like IE6 and IE7,IE8 also needs some hacks .Let the css is something like given below

.style1{ width:320px;}

If this css will not show perfect only in IE8 then we need to write

.style1{ width:320px;width:300px\9;}

Using ( \9 ) sign indicates that this css will render by only in IE8 Browser not any browser will understand it's meaning.
