What is the difference between transitions and animations?

Transitions define how property changes happen on events (like hover), while animations allow keyframe-based changes over time. For example, p { color: purple; } /* Specificity: 1 */ .button { color: orange; } /* Specificity: 10 */ #page-header { color: red; } /* Specificity: 100 */ /* Inline styles take priority: */ style="color: yellow;" /* Specificity: 1000 */
