Difference between jQuery selectors "ancestor descendant" and "parent > child"
<p>The following two forms of jQuery selectors seem to do the same thing:</p>

<ul>
<li>$("div > ul.posts") </li>
<li>$("div ul.posts")</li>
</ul>

<p>which is to select all the "ul" elements of class "posts" under "div" elements.</p>

<p>Is there any difference?</p>
