Your question is a bit unclear, but this should help:

If these are specific styles for IE I would recommended using a conditional stylesheets targeted specifically to the version of IE you are using.

Further information can be found on this Sitepoint article.

Its working perfect IE 7 and 8.

.sample{ height:15px; width:15px; margin:10px; padding:10px; float:left:

 border:1px solid #fff; /* For All browser's */  

 /*this one apply in ie only*/ 

   # border:2px solid green;   /* This one is IE 7 and below */ 

   border:2px solid red\0/; /* this one is IE 8 */

/*this one apply in ie only || for ie it treats as 2px.*/

}
