title: Delay in bootstrap toggle menu
body: <p>I have built a menu bar using bootstrap. In the responsive mode, when the toggle menu is activated, the menu list items comes up quickly while the background container comes with a delay. Similarly when the toggle mode is deactivated, the container disappears while the menu items disappear with a delay. I have uploaded a video of this issue here: <a href="https://drive.google.com/file/d/0BwJk1FZoR5hXa3VsaHM4QTF0TDQ/view?usp=sharing" rel="nofollow noreferrer">Video</a> 
  <br><br>Kindly, please let me know how to solve this problem.</p>
