What's a spacer.gif?

In the days of HTML-table based web design, a transparent 1×1 pixel gif was often used to hold open empty HTML table cells in a page layout. The image could be resized to any dimensions and invisibly prevent a table cell from collapsing and ruining a layout.

Today, modern CSS relies less and less on these kinds of "design hacks", and allow for more layout possibilities than ever before. But some email clients are stuck in the past and most email designs need to be coded with these ancient HTML-table layout techniques to accommodate them.
