animation-duration: 10s;
background-color: blue;
height: 100px;
width: 100px;
position: relative;
}

from {

}
to {

<p>
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.

var div = document.getElementsByTagName("div");

function animationStart() {
div[0].innerHTML = "START";
}

div[0].innerHTML = "END";
