CSS display none and opacity animation with keyframes not working
The display doesn't work with CSS transition or animation.
Use opacity, visibility or z-index. You can combine all them.
Try to use visibility: visible in place display: block and visibility: hidden in place display: none.
And finally, combine z-index: -1 and z-index: 100 for example.
Good work ;)
If you are using @keyframes you should use -webkit-animation instead of -webkit-transition. Here is the doc for @keyframes animation: https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Using_CSS_animations.
See code snippet below:
.parent {
background-color: #000;
color: #fff;
width: 500px;
height: 500px;
padding: 5px;
}
.myDiv {
display: none;
opacity: 0;
padding: 5px;
color: #600;
background-color: #cec;
}
.parent:hover .myDiv {
display: block;
opacity: 1;
/* "both" tells the browser to use the above opacity
at the end of the animation (best practice) */
-webkit-animation: display-none-transition 1s both;
animation: display-none-transition 1s both;
}
@-webkit-keyframes display-none-transition {
0% {
opacity: 0;
}
}
@keyframes display-none-transition {
0% {
opacity: 0;
}
}<div class="parent">
Hover on me...
<div class="myDiv">Hello!</div>
</div>2016 UPDATED ANSWER
To reflect today's best practices, I would use a transition instead of an animation. Here is the updated code:
.parent {
background-color: #000;
color: #fff;
width: 500px;
height: 500px;
padding: 5px;
}
.myDiv {
opacity: 0;
padding: 5px;
color: #600;
background-color: #cec;
-webkit-transition: opacity 1s;
transition: opacity 1s;
}
.parent:hover .myDiv {
opacity: 1;
}<div class="parent">
Hover on me...
<div class="myDiv">Hello!</div>
</div>
