div {
animation-name: sample;
animation-duration: 10s;
background-color: blue;
height: 100px;
width: 100px;
position: relative;
}
@keyframes sample {
from {

}

Test passes if there is a filled blue square,
which moves from right to left with text 'START'
and changes to 'END' when the animation is finished.
