Remove vertical white space

[TecBrat]

More than likely you are seeing the <br class="ClearBoth"> which is creating your "whitespace" - correct this by changing it to <div class="clearBoth></div>

Thanks Tina.
Those were around lines 65 and 92 of tpl_header in the common folder. Those changes resulted in changes in the space above the logo, where the home, log in, and other links appear, as well as the search box. My issue is below the logo, between it and the rest of the content such as the sideboxes and the area filled in by main_page=

Any other suggestions?
