title: Get URL-prefix like matching, using RegEx in Stylish?
body: <p>I am coding custom CSS for Facebook using <em>Stylish</em>.<br>
  Everything goes well except that I need to have some custom values under the condition of URL-suffix. The only thing that comes close is URL-prefix which is the exact opposite.</p>
  
  <p>So I was wondering if I could do something like:</p>
  
  <p>Detect if URL is like either:<br>
  <code>www.facebook.com/*/posts</code>  or just  <code>*/post</code></p>
  
  <p>where * could be any value.
  Is it possible to do this through RegEx?
  I googled it but I couldn't make anything out of it.</p>
  
  <p>I want to apply some CSS code only when viewing some individual Facebook posts, and the URLbar shows:</p>
  
  <pre><code>www.facebook.com/User/Posts/PostID.php
  </code></pre>
  
  <p>Therefore, I would only like to detect if Post or post/postID.php exists and apply the style.</p>
