Web Animations API adds support for CSS pseudo-elements

Recent updates to the Web Animations API have introduced support for animating CSS pseudo-elements, such as ::before, ::after, and ::marker. This functionality is now available in the latest versions of major browsers, including Firefox, Safari, Edge, and Chrome.

While these advancements improve web capabilities, developers are encouraged to utilize progressive enhancement strategies. Because many users operate on older devices or operating systems that cannot update to the latest browser versions, providing fallbacks ensures that essential content and functionality remain accessible even when newer CSS features, such as aspect-ratio, are unsupported.
