I did a slow infinite CSS3 animation. It animates from top:0; to top:40px;. The error is when the animate ends, it jumps to the start point. I think it should jump with easeor ease-in but that's not happening. I tried a lot to fix this, but I failed.
I need the return transition to have an ease-in effect.
My Code:
span {
margin-left: 200px;
}
/** Down Slow Animation **/
@-webkit-keyframes downSlow {
from { top: 0px; }
to { top: 40px; }
}
@-moz-keyframes downSlow {
from { top: 0px; }
to { top: 40px; }
}
@keyframes downSlow {
from { top: 0px; }
to { top: 40px; }
}
.down-slow {
position: relative;
-webkit-animation: downSlow 1.5s infinite;
-moz-animation: downSlow 1.5s infinite;
animation: downSlow 1.5s infinite;
-webkit-animation-fill-mode: forwards;
-moz-animation-fill-mode: forwards;
animation-fill-mode: forwards;
}
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet" />
<span class="down-slow"><i class="fa fa-angle-down fa-5x"></i></span>
This is just an alternative solution
Just add alternate ant the end of animation.
span {
margin-left: 200px;
}
/** Down Slow Animation **/
@-webkit-keyframes downSlow {
from { top: 0px; }
to { top: 40px; }
}
@-moz-keyframes downSlow {
from { top: 0px; }
to { top: 40px; }
}
@keyframes downSlow {
from { top: 0px; }
to { top: 40px; }
}
.down-slow {
position: relative;
-webkit-animation: downSlow 1.5s infinite alternate;
-moz-animation: downSlow 1.5s infinite alternate;
animation: downSlow 1.5s infinite alternate;
}
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet" />
<span class="down-slow"><i class="fa fa-angle-down fa-5x"></i></span>
The same code can be reduce to
span {
margin-left: 200px;
top: 0px;
}
@-webkit-keyframes downSlow {
to { top: 40px; }
}
@-moz-keyframes downSlow {
to { top: 40px; }
}
@keyframes downSlow {
to { top: 40px; }
}
.down-slow {
position: relative;
-webkit-animation: downSlow 1.5s infinite alternate;
-moz-animation: downSlow 1.5s infinite alternate;
animation: downSlow 1.5s infinite alternate;
}
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet" />
<span class="down-slow"><i class="fa fa-angle-down fa-5x"></i></span>
A much better approach would be to use translate this way your element will not interfere with other DOM elements
span {
margin-left: 200px;
}
@-webkit-keyframes downSlow {
to { transform: translateY(40px) }
}
@-moz-keyframes downSlow {
to { transform: translateY(40px) }
}
@keyframes downSlow {
to { transform: translateY(40px) }
}
.down-slow {
position: relative;
-webkit-animation: downSlow 1.5s infinite alternate;
-moz-animation: downSlow 1.5s infinite alternate;
animation: downSlow 1.5s infinite alternate;
}
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet" />
<span class="down-slow"><i class="fa fa-angle-down fa-5x"></i></span>
But again you can reduce this with prefixfree frind a cdn here
span {
margin-left: 200px;
}
@keyframes downSlow {
to { transform: translateY(40px) }
}
.down-slow {
position: relative;
animation: downSlow 1.5s infinite alternate;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet" />
<span class="down-slow"><i class="fa fa-angle-down fa-5x"></i></span>
at the end set speed/2
span {
margin-left: 200px;
}
@keyframes downSlow {
to { transform: translateY(40px) }
}
.down-slow {
position: relative;
animation: downSlow .7s infinite alternate forwards;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet" />
<span class="down-slow"><i class="fa fa-angle-down fa-5x"></i></span>
