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.
