Accessibility notes
- Each handle is a focusable
separator, as in the WAI-ARIA window splitter pattern: its value is the size of the pane before it, between that pane’s limits, andaria-controlspoints at the pane. - Name the handles through the panes’
label: “Files” tells a screen reader what a handle resizes. - A double click on a handle folds its pane too, and a drag captures the pointer, so fast moves don’t lose the handle.
