The menu taps are made with HTML and CSS. It's all in the code:

HTML:

Code: <div id="header">

<ul>
<li><a href='/'>Home</a></li>
<li><a href='/tutorials/'>Tutorials</a></li>
<li class='selected'><a href='/forums/'>Forums</a></li>
<li><a href='/about/'>About</a></li>

</ul>
<form method="get" action="/search/" id="cse-search-box">
<div id="searchbar">
<span>

<input type="text" name="q" id="query" value="" /><input type="submit" id="submit" value="Search" />
<input type="hidden" name="cx" value="002160260272865772965:d4fb4jd-jh0" />
<input type="hidden" name="cof" value="FORID:11;NB:1" />
<input type="hidden" name="ie" value="UTF-8" />
<input type="hidden" name="lr" value="lang_en" />
<input type="hidden" name="hl" value="en" />

</span>

</div>
</form>
