tag not working in increasing height between logo and nav bar

Totally new to 3rd party themes but I bought one from Elegant Themes (I cant find support documentation on this topic on their site). Is there a way to increase the height between the nav bar and the logo so the logo is completely shown (right now it isnt)? I went to Appearance<Editor<Header.php and then went to this line of code (you can do CTRL F to locate it):

<a>"><?php $logo = (get_option('elegantestate_logo') <> '') ? get_option('elegantestate_logo') : get_template_directory_uri().'/images/logo.png'; ?>
      <img src="<?php echo esc_url($logo); ?>" alt="<?php echo esc_attr(get_bloginfo('name')); ?>" id="logo"/></a>

[please mark any posted code – http://codex.wordpress.org/Forum_Welcome#Posting_Code – the above code is corrupted by the forum’s parser]

If i put above this line of code it will cover the logo up more but if I put it after this line of code it will have no affect on the spacing.

Any thoughts on why this isn’t working? Seems like this would be an easy fix but since that didn’t work not sure why!
