CSS properties allows us to change style of HTML element smoothly. CSS3 introduce two keywords for animation:
@keyframe and animation. Both properties can bind with any HTML element like text, div, span etc.
(1) @keyframe has a collection of CSS style properties. It is like a timeline of CSS styles.
(2) animation property can control keyframes execution sequence.
Select any predefined samples from top panel. Below samples there is a timeline of @keyframes. Timeline has 101 keyframes ( 0% to 100%) direction from left to right. Highlighted keyframe indicate that some style is assigned to that point. You can add new style at selected point.
