Hiding Items in CSS: Display vs. Visibility

When you want to use an iEBMS Stylesheet to hide specific elements on a page, there are two ways to go about it that will affect the layout of the iEBMS page.  The first is setting Display: none.  Using the Display property and setting it to None will make the page display as though the element was never there.  This may, however, cause changes in the layout of the page as other elements may move to fill the space that was once occupied. 

If elements move around and you wish to preserve the original layout of the page, instead use Visibility:hidden.  This will hide the element from the page, but the space it once occupied will still be reserved.
