Observation Details
The content cards can only be operated by horizontal scroll or by dragging movement on smaller viewports / mobile. As the dragging needs a base precision to stop the movement at the right time to reach the wanted content card, a single pointer alternative for operation / navigation must be offered.
Remediation Notes
Possible methods to remediate and to ensure access to the links:
Adding pagination (single pointer arrow buttons)
Reflow to multiple lines (also see 1.4.10 Reflow)
Note, that the WCAG, and success criterion 2.5.7 Dragging Movements specifically, do not require presentation / layout parity of different devices, viewports, etc. This means, while functionality and information parity is a must, the layout and presentation can be different.
