div {
animation-name: sample;
animation-duration: 10s;
animation-direction: alternate-reverse;
animation-iteration-count: infinite;
background-color: blue;
height: 100px;
width: 100px;
position: relative;
}
@keyframes sample {
from {
left: 0px;
}
to {
left: 150px;
}
}
</style>
<body>
<p>
Test passes if there is a filled blue square with 'Filler Text',
which starts moving from right to left on the page load,
and then moves from left to right. This cycle gets repeated.
</p>
<div>Filler Text</div>
</body>
