The ">" is the direct child selector. The item on the left must be the direct parent of the item on the right.

A space creates a descendant selector, where the item on the left must be a container of the item on the right, but there could be any number of elements in between.

They are likely to appear to work similarly, because the rules of HTML say that all the children of a "ul" must be "li" elements. But where lists are nested they could differ. For example:

<ul>
  <li>                  <!-- this would be selected by either -->
    <ol>
      <li> ... </li>    <!-- this would be selected by "ul li" but not by "ul > li" -->
    </ol>
  </li>
</ul>
