Add life to your websites with smooth CSS transitions and complex, keyframed animations.
CSS transitions and animations allow you to create dynamic visual effects that enhance user experience without needing JavaScript. They provide a way to animate changes in CSS properties, making UI elements feel more responsive and engaging. Transitions are the simpler of the two. They are used to smoothly animate a change from one state to another, typically triggered by a pseudo-class like `:hover` or `:focus`. You define a transition using the `transition` property, specifying which CSS property to animate (`transition-property`), how long the animation should take (`transition-duration`), the timing function (`transition-timing-function`, e.g., `ease-in-out`), and any delay (`transition-delay`). For example, you can make a button smoothly change color and size when a user hovers over it. Animations are more powerful and give you granular control over a sequence of effects. They are defined using the `@keyframes` rule, where you specify the styles for different points in the animation's timeline (e.g., at `0%`, `50%`, and `100%`). You then apply this keyframe sequence to an element using the `animation` property, where you can define the animation's name, duration, iteration count, direction, and more. Animations are perfect for more complex effects like loading spinners, attention-seeking elements, or introductory sequences.
