WCAG 2.5.1: Pointer Gestures
WCAG 2.5.1 Pointer Gestures is a level A success criterion from WCAG 2.1. Anything that needs a multi-point or path gesture, such as pinch or swipe, also has a single-pointer alternative.
People who cannot pinch need another way to zoom a photo or move a slider.
How to test
Find carousels and maps. Arrows or buttons should do the same job as a swipe.
How to fix
Add next and previous buttons.
Example that fails
The product gallery moves only by swiping.
Example that passes the check
Next and previous buttons sit beside the gallery.
Shopify
Enable the thumbnail or arrow controls on the product media gallery.
WooCommerce
Add arrow controls to the product gallery script.
WordPress
Gallery blocks should expose next and previous buttons.
Wix
Turn on slideshow arrows, not swipe only.
