Optin Box Code - help

Hi There warriors

I would apprecaite if someone could help me with simple coding my optin box.

I want the background colour of the box to be 31780C. But don't know where to place this colour code and also I would like to narrow the gap between the top text and the writing fields below it.

The optin is at thefabdiet.com/blog

My code is:

<div class="optin_former2">

<div class="ebook_holder2">
<img src="http://thefabdiet.com/blog/wp-content/uploads/2011/01/ebook-hover-cover-4.png" />
</div>

<div class="optin_heading2">Download Your Copy Of &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The F.A.B Diet Book Now!</div>
<span class="optin_text2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;Follow a 3 step system to lose weight<BR>
