On the site

After the module is published and assigned, open that page like a visitor.
Checklist
- Status is Published, Position is correct, and Menu Assignment matches the page.
- At least one slide has a real image.
- Clear Joomla cache, then hard-refresh (Ctrl+F5).
- Click the slider and use the arrow keys. On a phone, swipe.
Live demo variants
The public hub at demo.joomlax.com/demo/utilities/revealing-photo-slider includes Circle, Wipe, Split, Diamond, Folder, and Articles. The screenshot shows the Diamond variant with an 18px radius and soft shadow.
Several sliders on one page
Each module gets its own id, and the CSS and JS load only once. Two sliders on one page run independently.
