Possible Values

sWidth String that specifies one of the following values:

The property is supported on block and replaced objects only.

<HEAD>
<STYLE>
    TD { border-top-width:3mm }
    .changeborder1 { border-top-width:1cm }
</STYLE>
</HEAD>
<BODY>
<TABLE BORDER>
<TR>
    <TD onclick="this.className='changeborder1'"
        ondblclick="this.className=''">
