how do i insert border in div tag?? the div tag similar to text areas but can have html in it..

After the first part of the div tag which should look something like below,
<div style="position:absolute; top:#; left:#; width:#; height:414; background:#000000;

you add the following code the parts in red being the varibles
border-color: 000000 ;
border-style: solid;
border-top-width: 1px;
border-right-width: 1px;
border-bottom-width: 1px;
border-left-width: 1px;"

Don't forget to add a '>' afterwards and a '</div>' once you've finished the content of the div layer
