Q: What's the performance impact of Sal on scrolling?

Sal has minimal impact due to Intersection Observer, which offloads visibility checks to the browser instead of using scroll listeners. Its lightweight size (2.8 kB) ensures fast loading, making it suitable for content-heavy pages.

Question 1

Sal vs AOS: which is better for scroll animations?

Accepted Answer

Sal is lighter (under 3 kB) and uses Intersection Observer for optimal performance, while AOS offers more animation types but with a larger footprint. Choose Sal for modern, performance-focused sites, and AOS if you need a broader animation set with some overhead.

Question 2

How to use Sal with React or Vue?

Accepted Answer

Sal is vanilla JS, so integrate it by initializing in a useEffect or mounted hook and applying data-sal attributes to elements. For dynamic content, use the update() method to refresh animations, as described in the API section.

Question 3

Does Sal work with CSS frameworks like Tailwind?

Accepted Answer

Yes, Sal's animations are defined via data attributes and its own CSS, so it can coexist with Tailwind. You may need to manage style conflicts, but Sal's minimal CSS allows easy overrides or integration.

Question 4

Can I create custom animations with Sal?

Accepted Answer

No, Sal does not support defining new animation types; you're limited to the built-in effects like fade and slide. For custom animations, you'd need to extend the CSS or use Sal's events to trigger external libraries.

Question 5

How to disable Sal animations on mobile devices?

Accepted Answer

Use the disabled option with a function, e.g., sal({ disabled: () => window.innerWidth < 768 }) to disable based on viewport width, as shown in the Options table for flexible control.
