Border for table cell rollover

[svoltmer]

Hi, I have a navigation table with cells that change states using "onmouseOver" to add "style.border=('1px sold black');" . But this causes the navigation table cells to expand to include the 1px border, which in turn pushes the items in the table cell adjacent to the navigation. This makes for a jumpy look when the rollover is moused over. Any suggestions on how to stop the table cells from expanding and contracting on my "onmouseOver" and onmouseOut" states? Thanks!

I would use a border right from the start and use the background color to style the border with. That way it doesn't change the size since it is there it just isn't visable.
