So how do i make outro animation on CSS???

Answer 1

You could use this code:

 .dropdown { position: relative; width: 200px; } .dropdown-content { position: absolute; background-color: #f9f9f9; margin-left: 200px; box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2); padding: 12px 16px; z-index: 1; width: 600px; opacity: 0; -webkit-transition: all 0.4s linear; -moz-transition: all 0.4s linear; -o-transition: all 0.4s linear; transition: all 0.4s linear; } .dropdown:hover .dropdown-content { opacity: 1; } 

 <div class="dropdown"> <span>Hover me!</span> <div class="dropdown-content"> <p>CONTENT</p> </div> </div> 

Or you could change the linear to another transition of your choice.

By using -webkit-transition , -moz-transition , -o-transition & transition you have support for most popular browsers.

If you have anymore questions or you want something different, just ask me.

Here is a fiddle with linear transitions: https://jsfiddle.net/f5ryq3yg/ (graph http://easings.net/ at the top of the page)

Or one with ease-in-out transitions: https://jsfiddle.net/skvykpsj/1/ (graph http://easings.net/#easeInOutSine )

All you need to do is create animation.

@keyframes { 0%{ margin:0; } 100%{ margin:100%; }

etc.
