The difference between IE and ff CSS styles

The FF interpretation of the box model is also different, code description: #test {width:650px!important;width:648px;padding-left:2px;background: #fff;}
Test shows the broadband is 650px
The total width of IE box is: width+padding+border+margin width sum
The total width of the FF box is width, and the width of the padding+border+margin is contained within the widths.
If there are box{width: "300"; PADDING: "5PX";}
Then box in the IE width should be: 310
and the width in FF is 300.
So it should be used in case the box has a fill.
Box{width: "290"! IMPORTANT; WIDTH: "300";}
This way to ensure that box width is always 300px, without the phenomenon of distraction

Five: the UL label in Mozilla has padding value, and in IE only margin have value.
Set ul{margin:0;padding:0}

Now write a CSS can do this:
#1 {color: #333;}/* Moz/*
* HTML #1 {color: #666}/* IE6 * *
*+html #1 {color: #999;}/* IE7 * *
Then in Firefox font color display for #333,ie6 under the font color display for #666,ie7 under the font color display as #999
can use "+" to realize only IE recognized CSS Hack
may have friends think of using "_" Hack, but they are distinguished, because the IE7 is not recognized "_". So use +
Test results:
IE5.5,IE6, IE7 browser can identify;
Ff2.0,opera 9,safari 2 Browser does not recognize
