A couple of questions regarding jQuery's $(document).ready and its use
<p>I have been writing some basic Javascripts, and I am finally giving in to try to learn jquery (less than 24hrs).  I am having a problem with understanding syntax with simple lessons/codes that I am tweaking for my purpose.</p>

<p>Does everything has to be wrapped inside a separate $(document).ready(function())?</p>

<p>Or just have 1 $(document).ready(function()) statement and stuff everything inside of it?  Including custom functions.</p>

<p>What happens when you put one inside another?</p>

<p>Sorry for simple question, but the examples online or in my book has the declaration wrapped around the executing code.</p>
