在侧边栏菜单上显示覆盖打开

Question

I want to show an overlay when then sidebar menu opens. And close the menu when the overlay is clicked.

here is what i've done:

 $(document).ready(function() {

    $('#menu-toggle').click(function(e) {
      e.preventDefault();
      $('#wrapper').toggleClass('toggled');
      $('#overlay').toggle();
    });

    $('#overlay').click(function() {
      $('#overlay').hide('200');
      $('#wrapper').removeClass('toggled');
    });
  });


#overlay {
  position: fixed;
  z-index: 999;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  display: none;
  background-color: rgba(0,0,0,.5);
}

here is the demo - https://jsbin.com/vasisedoha/edit?css,js,output

my code is working fine.

I'm stuck at making the animation look good. Please help me fix the animation effect.

Try the below,

You can use jQuery fadeIn and fadeToggle functions

  $(document).ready(function() { $('#menu-toggle').click(function(e) { e.preventDefault(); $('#wrapper').toggleClass('toggled'); $('#overlay').fadeToggle( "slow", "swing" ); }); $('#overlay').click(function() { $('#overlay').fadeOut('slow'); $('#wrapper').removeClass('toggled'); }); });
