How can I reduce depth of a 3 code blocks on the same row

I have created 3 code blocks (each 1/3. 1/3, 1/3) in a color section atop my home page of esomethin.com/yoursource. Each code block contains a search form. One of the code forms is a google form; the other 2 are search forms grabbing information from databases on a company intranet.

I want to reduce the depth search forms because the gray area is too deep.. Can you please help me tighten up the depth of this top color section?

I have include information on Private Content below.
Thanks,
