Trouble lining up search in sidebar…

I have added a search feature to my sidebar.
The website is at http://www.babybumps.net/blog
The code for the searchform.php is as follows:

<div id="ssubmit"><form method="get" id="searchform" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<div><input type="text" value="<?php echo wp_specialchars($s, 1); ?>" name="s" id="s" />
<input type="image" src="http://www.babybumps.net/blog/wp-content/themes/BB%20design/images/searchicon.gif" width="33" height="28" border="0" alt="Submit" id="searchsubmit" />
</div>
</form>
</div>

I am ready to adjust it a bit using CSS. All I need to do is to adjust the width of the search bar and indent it to where it lines up with the image under categories, but nothing I am adding to the styles file seems to be making a difference. Any thoughts?

P.S. I know that there are some browser issues in Mozilla and Safari, so please use IE to look at it. Still troubleshooting that issue. If you have any suggestions as to what might be causing that problem let me know… it seems like the CSS just drops out of the blog after the navigation file…
