I have this CSS used to draw a frame around a table cell:

.ch
{

margin : 0;
padding-left : 0%;
padding-right : 0%;
border-style : solid;
border-right-width : 1px;
border-left-width : 1px;
border-top-width : 1px;
border-bottom-width : 1px;
margin : 3px;
padding: 0px;
border-color : #888888;

}

Used like this:
<table>
<tr><td class="ch">Hello</td></tr>
</table>

This CSS works fine in all browsers except in Netscape 4.x.
Can anyone tell me why???
