CSS implementation to div4 corner plus fillet picture

First look at the CSS style:

. border{background: #ffecf9; border:1px solid #ffd3ec; width:500px; position:relative;}

. lt{Background:url (... /images/border_lt.gif) No-repeat; left:0; top:0; Position:absolute; width:7px; HEIGHT:7PX;}
. rt{Background:url (... /images/border_rt.gif) No-repeat;  right:0; top:0; Position:absolute; width:7px; HEIGHT:7PX;}
. lb{Background:url (... /images/border_lb.gif) No-repeat; left:0; bottom:0; Position:absolute; width:7px; HEIGHT:7PX;}
. rb{Background:url (... /images/border_rb.gif) No-repeat; right:0; bottom:0; Position:absolute; width:7px; HEIGHT:7PX;}

. content{}

Code:

this is content.

The style of the Border_lt.gif 4 pictures is a div 4 fillet picture, need to cut out their own complete, size, depending on the situation
The position is absolutely controlled by left, top, right, and bottom.

Description

2. lb{Background:url (... /images/border_lb.gif) No-repeat; left:0; bottom:0; Position:absolute; width:7px; HEIGHT:7PX;}
Here, the definition of location, ie may be a little bit different, for IE special settings, examples are as follows:

. lb{Background:url (... /images/border_lb.gif) No-repeat; Left:-1px!important; left:-5px; Bottom:-1px!important; bottom:-5px; }
