  In basic view, I have vertical borders.</p>
  
  <p>I already tried what I found in this post <a href="https://stackoverflow.com/questions/22465392/fullcalendar-dividing-lines-between-days">FullCalendar dividing lines between days</a> without any success.</p>
  
  <p>I'm using fullcalendar along with zurb foundation.</p>
  
  <p>Thank you for your help !</p>
