变换与动画

The terms transitions and animations are often used interchangeably but are not, in my experience, one and the same:

  • A transition is a simple change in the style properties on an element to be transitioned in a single step. They are often handled purely through CSS.

  • An animation is a more complex, usually multi-step and sometimes continuous change in appearance. Animations will often call on JavaScript to pick up where CSS' lack of logic drops off. It could be to add a class and trigger the animation or to make complex state transitions that reflect onto the DOM.
