Split-Pane Layout Resizable Only by Dragging the Divider
2.5.7 — Dragging Movements
Scenario
Setting
A language-learning app's lesson screen
What’s wrong
Split-pane resizing only by dragging the divider.
Example
On a language-learning app's lesson screen, a visitor hits this wall: split-pane resizing only by dragging the divider.
Why it matters
People with limited dexterity and switch, eye-gaze, or voice users who cannot drag. Here, on a language-learning app's lesson screen, the result is they can't complete the task using a keyboard alone.
How to test
Try resizing a split-pane layout via a button, keyboard shortcut, or preset sizes instead of dragging the divider: if drag is the only method, it fails.
How to fix
A single-pointer, non-dragging alternative (buttons, menu option, tap) must exist for the drag operation.
Outcome
After the fix, the same visitor to a language-learning app's lesson screen can now keep track of where they are on the page.
Who is affected
People with limited dexterity and switch, eye-gaze, or voice users who cannot drag.
