Introduction

The CSS animations specification “describes a way for authors to animate the values of CSS properties over time, using keyframes. The behavior of these keyframe animations can be controlled by specifying their duration, number of repeats, and repeating behavior.” (CSS Animations Level 1, W3C Working Draft, 30 November 2017).

div {
    -webkit-animation: mykeyframes 5s; /* Chrome, Safari, Opera */
    animation: mykeyframes 5s;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes mykeyframes {
    from {background: red;}
    to {background: yellow;}
}

/* Standard syntax */

    to {background: red;}
}
