Accordion Design Best Practices (2026)

An accordion is a stack of headers that expand to reveal content one section at a time. It is great for compressing long pages, and risky when it hides things people need to see.

This guide covers when an accordion helps, how to structure one, and the mistakes to avoid.

When to use an accordion

Use an accordion when a page has several distinct sections that not everyone needs at once, such as an FAQ, product details, or settings. It keeps the page short and lets people jump to what they want.

Avoid it for content people should read in full, or for anything you want indexed and visible. If hiding the content hurts understanding, leave it open.

The anatomy of an accordion

• Header. A clear, clickable label for each section.
• Indicator. A chevron or plus that shows open or closed state.
• Panel. The content revealed when expanded.
• Behavior. Whether one panel or several can be open at once.

Accordion design best practices

• Write headers that clearly describe what is inside.
• Show a clear open and closed indicator, and animate the change smoothly.
• Make the whole header clickable, not just the icon.
• Decide deliberately whether multiple panels can stay open.
• Keep each panel reasonably short. If it is huge, a separate page may be better.
• Do not hide critical information or primary actions inside collapsed panels.

Accessibility

Accordion headers should be real buttons, reachable and toggleable by keyboard, with state announced to screen readers so people know whether a section is open or closed. See accessibility for the essentials.

Common accordion mistakes

• Hiding important content that should simply be visible.
• Vague headers that do not hint at the content.
• Only the icon is clickable, so the target is tiny.
• No clear indicator of open versus closed.
• Nesting accordions inside accordions until it is a maze.

Frequently asked questions

When should I use an accordion?

Use one for several distinct sections that not everyone needs at once, like an FAQ or detailed specs, where keeping the page short helps.

Should multiple accordion sections open at once?

It depends. Allow multiple when people compare sections. Limit to one when focus matters and the page would get too long.

Is hiding content in an accordion bad for SEO?

Modern search engines can read content inside accordions, so it is generally fine. Still, keep your most important message visible by default.

Are accordions good on mobile?

Yes, they shine on mobile by shortening long pages, as long as headers are clear and tap targets are large.

What is the difference between accordions and tabs?

Accordions stack sections vertically and suit long content. Tabs switch between a few peer views in the same space.
