title: How to make a slider continue the loop even if its elements ends (how to wrap a slider)?
body: <p>I created a slider with <code>css</code> and html and <code>jQuery</code>.The slider is working great with next button but not whit previous button. </p>
  
  <p>Let us say I have five element on the first slide and total 15 elements . 
  so If I click next for three times the elements will end. On the forth click it should show the first five elements (and that is working good) BUT If I click previous button for the first time it should show me the last five elements from 11-15 but it does not do this. It is still showing me the next five element from 6-10.</p>
  
  <p>This link will explain what I want to say :</p>
