What CSS properties does the animation generator produce?

The generator creates two pieces of CSS: the @keyframes rule (which defines the animation frames) and an animation shorthand property applied to a CSS class. The shorthand combines animation-name, animation-duration, animation-timing-function, animation-delay, animation-iteration-count, animation-direction, and animation-fill-mode into a single declaration.

What is animation-fill-mode and when should I use it?

'forwards' keeps the element at the last keyframe state after the animation ends — great for entrance animations like fade-in. 'backwards' applies the first keyframe during the delay period. 'both' combines both behaviors. 'none' returns the element to its original state after the animation.

How do I apply the generated animation to a specific element?

Copy the @keyframes block and the .animated class into your CSS file, then add the class to any HTML element: . You can also copy just the animation property value and apply it inline or within any existing CSS rule.

Can I create custom multi-step animations?

The generator provides common presets (fade, slide, bounce, spin, etc.) with predefined keyframes. For fully custom animations with arbitrary keyframes, you'd need to hand-edit the @keyframes block — the generator output gives you a solid starting template to modify.

Does CSS animation work on all browsers?

Yes, CSS @keyframes and the animation property are supported in all modern browsers (Chrome, Firefox, Safari, Edge). The generator uses the standard unprefixed syntax, which is sufficient for all browsers with more than 0.5% global usage. IE 10+ also supports CSS animations.
