title: jQuery UI Tabs - How to represent an active tab using a down arrow (instead of the standard style)
body: <p>One of my service pages needs inner tabs. 
  I already use regular jQuery UI Tabs in the page and I would like to use a different styling for the inner tabs. </p>
  
  <p>Many popular sites use inner tabs differently from the main tabs by using simple text for the tabs titles, a long underline beneath the titles and a down arrow to represent the selected tabs. (image attached).</p>
  
  <p>Do you know how to style jQuery UI Tabs to place a down arrow when the tab is selected?</p>
