CSS Transitions when display:none is set -

How can you change properties with the display of elements using CSS? My current solution is to set a display to block with Javascript, wait 10 milliseconds for repaint, then apply the class that I want to amimate.

Note: I'm using jQuery for code summarize.

CSS - animating opacity as an example. Do not care about $. Show ().

  .element {display: none; Opacity: 0; -WebKit-Infection: all 0.5 s; -Mozy infection: all 0.5 s; -M transition: all 0.5 s; -O-Infection: All 0.5 S; Infection: all 0.5 s; } .element.shown {Opacity: 1; }   
 
 javascript  
  function show () {var $ element = $ ('. Element'); $ Element.css ({display: 'block'}); // Display the class in the block, then add the class after a few seconds, otherwise the animation css changes set timeout (function () ($ element.addClass ('shown');}, 10);} hide the function () $ {Element} = $ ('Element'); $ Element.removeClass ('detected'); // Remove element from transition after transition; $ element ends ('WebCat TransactionAntendedandArtentationAnd' MSRCIndex Transitionand ', F I think that, however, a CSS-only way should be a better way. I just got the workaround. You just need to use the animation and you can see the display. Start it a little bit after applying: block like this:  
  @keyframes submenu_animation {{from opacity: 0;} 1% {opacity: 0;} 99% {opacity: 1 ;} {Opacity: 1;}} Li Ul Clarity: 0; Do not display anything; Animation-name: submenu_enimation; Animation-period: 300ms; Animation-direction: reverse; Li ul.open {display: block; } Li: Hove ul (Animation-direction: normal; Opacity: 1; }   
 Javascript is very similar, once you hover over the required element, this "open" square will apply when you hover out, After sometime, the "Open" class will remove.
