TIPS: write different CSS for different browsers to be compatible with browsers

When I was doing something, I found that what I did in ie6.0 was totally invisible to ff.
100% CSS incompatibility I have read the relevant information. I personally feel that the following is a stupid and quick way to solve the compatibility problem.
The method is used to write different CSS for different browsers! Important, but IE7 and FF are not good.
The better way is sample.
Padding: 0px;/** // * FF write like this */
* Padding: 0px;/** // * write in ie7.0 */
_ Padding: 0px;/** // * write in ie6.0 like this */

The sequence is to write FF first, then ie7.0, and then 6.0.

FF in standard format
Add one for ie7.0 *
Ie6.0 Add _
