AniJS is a small JavaScript library (~8kb gzipped) that lets you add CSS3 animations and UI interactions using declarative data-anijs HTML attributes, with no third-party dependencies. It works across modern browsers and mobile devices, enabling designers to build animated UI components without writing code.

Use cases

• add css animations to html elements without javascript
• trigger animation on click or scroll
• build animated ui components like tabs and modals
• declarative scroll reveal animations
• animate elements on mouseover
• let designers add interactions without coding

When to choose

• you want declarative, attribute-based CSS3 animations with zero dependencies
• designers need to add interactions without writing JavaScript
• you need a tiny animation library for modern browsers and mobile

When to avoid

• you need complex JavaScript-driven animation timelines or physics-based motion
• you use a modern framework with its own animation ecosystem (e.g. Framer Motion, GSAP)
• you need actively maintained software with recent releases
