SEO and Performance

Slider Block follows best practices for:

Troubleshooting

The slider doesn’t autoplay:
Check the block settings and ensure “Autoplay” is toggled on. Autoplay is disabled by default for accessibility reasons.

Keyboard navigation not working:
If multiple sliders are on a single page, ensure you’re using version 1.1.0 or later (this fixes navigation conflicts).

Layout issues on mobile:
Try adjusting the “Slides per view” setting or resetting custom CSS if applied by your theme.

Integrations

Compatible with WooCommerce product blocks.
Can be combined with block patterns and reusable blocks for advanced layouts.
