Behavior comparison

Accordion vs Tabs

Decisive difference

Accordion stacks sections whose content appears beneath each heading; Tabs swap one panel for another and show only one at a time.

AccordionChoose Accordion if several sections may stay open at once and read top to bottom, like a FAQ.
TabsChoose Tabs if the views are peers and only one should occupy the space at a time.

Decision

Should the control switch views, choose a compact mode, or reveal content in the flow?

Dimension	AccordionAccordion	TabsTabs
Trigger	Click, tap, Enter, or Space on a section heading button.	Click, tap, or keyboard activation of a tab; arrow keys move within the tab list.
Modality	Non-modal disclosure inside the document flow.	Non-modal navigation between related panels in the same context.
Placement	Vertically stacked headings with each panel directly following its control.	A tab list directly adjacent to the panel controlled by the active tab.
Interactivity	One or several content panels expand and collapse without changing page context.	One tab and panel are active; activation may be automatic or manual depending on loading cost.
Focus	Focus remains on the header button when its panel opens or closes.	The tab list is one tab stop; the visible panel is reachable in normal document order when it contains focusable content.
Dismissal	Each expanded panel closes by activating its own header when the product allows collapse.	Not applicable: selecting another tab replaces the visible panel without closing the component.
Accessible role	heading > button[aria-expanded][aria-controls] + region	tablist > tab + tabpanel
Use case	Organizing FAQ answers or optional detail sections	Grouping a few peer views in one workspace
Mobile behavior	Use full-width heading buttons and preserve the reading position as panels change height.	Keep labels readable in a horizontally scrollable list; avoid wrapping tabs onto ambiguous rows.
