The form is excellent but...

The form is excellent but I succeed to do alone some things. Fault mine because I is not expert and therefore I ask, if possible, a simple explanation.
What I succeed to make is change the dimension of the characters and the background of the block.

  <div class="block block-<?php print $block->module; ?>" id="block-<?php print $block->module; ?>-<?php print $block->delta; ?>" "style="background-color:#EEEEEE" ">
    <h4 class="title"><?php print $block->title; ?> </h4>
    <h5 class="content"><?php print $block->content; ?> </h5>
 </div> 

Well. I would like however change the color of the title and the color of the characters in the content. I experienced in a lot of manners without to succeed us!

You would be able, please, to say me how to do? Thanks and excuse for my English (I hope at least comprehensible)
