What problem does this address?

Currently, Gutenberg does not provide a native slider/carousel block. Users often rely on third-party plugins to create sliders, which can increase dependency, affect performance, and create compatibility issues.

For simple use cases (like showcasing images, testimonials, or featured content), users expect a built-in solution similar to other core blocks.

This creates frustration as even basic slider functionality requires external plugins.

What is your proposed solution?

Introduce a simple, lightweight Slider/Carousel block as part of the core block library.

Suggested features:

• Add multiple slides (images, text, or inner blocks)
• Navigation arrows (next/prev)
• Optional dots/pagination
• Basic autoplay option
• Responsive behavior
• Swipe support for mobile

Technical approach (optional suggestion):

• Could be built using existing block architecture (InnerBlocks)
• Minimal JS to avoid performance overhead
• Follow accessibility best practices (ARIA roles, keyboard navigation)

This would reduce dependency on plugins and improve the out-of-the-box editing experience.

Additional context

Many modern editors provide built-in slider components. Adding this feature would align Gutenberg with current UX expectations and improve usability for non-technical users.

I would like to work on this feature if it's approved.
