title: Fix header to top of page with horizontal scroll
body: <p>I have a navigation header at the top of every page. I'd like the user to be able to scroll the horizontal overflow with a scrollbar. I understand this isn't possible with just CSS, but can any help me with the JavaScript portion?</p>
  
  <p>If this is too general, I'll post my project's code, but it's pretty extensive.</p>
  
  <p>Ex:</p>
  
  <p>| Example Header | About | Contact | Bl | (Cut off)</p>
  
  <p>&lt;------------------> (Scroll bar)</p>
