Product page accordions and tabs: making detail sections accessible

Shipping, ingredients, and care details hide inside accordions and tabs on most product pages, and those widgets are frequent accessibility failures. The pattern an accessible accordion follows and how to check yours.

Why these little widgets matter

On a modern product page, the information that closes sales often sits inside collapsible sections: shipping and returns, ingredients or materials, sizing notes, care instructions. Accordions and tabs keep pages tidy, but each one is a tiny interactive machine, and machines built from clickable headings and hidden divs routinely fail the shoppers who navigate by keyboard or screen reader.

The failures are quiet. A keyboard user tabs past a heading that was never a button and cannot open the section at all. A screen reader user opens it and hears nothing change, or hears the whole page's content announced in the wrong order. The merchant sees a tidy page; a share of customers sees locked drawers with the returns policy inside.

What an accessible accordion does

Each section header is a real button, so it is focusable, operable with Enter and Space, and announced as a button. The button carries a state attribute that reports expanded or collapsed, and it points at the panel it controls, so assistive technology can connect the two. The panel itself appears and disappears in a way that matches the visual state, staying out of the tab order and the reading order when closed.

Tabs follow a stricter pattern: arrow keys move between tabs, the selected tab is identified, and only the active panel is reachable. Themes and apps implement these patterns unevenly, which is why the pattern names matter when you are choosing or briefing a developer: you are asking for the standard accordion and tab behaviors, not inventing your own.

Checking yours in five minutes

Put the mouse aside and tab to the product details area. Can you reach each section header, see the focus indicator, and open and close it with Enter or Space? If a header is unreachable, it is not a button in the markup, whatever it looks like. Then open a screen reader and listen: does it announce the section name, whether it is expanded, and then read the revealed content in place?

Also check the mobile version, where accordions are most common and most customized. And check state honesty: if the section looks open but the screen reader reports collapsed, the visual layer and the accessibility layer have divorced, a common result when a developer toggles a class and nothing else.

Fixing at the theme level

These widgets live in your theme or a details app, so fixes propagate: repair the accordion component once and every product page improves. If your theme is current and reputable, check for updates and the vendor's accessibility notes first. If a details app generates the sections, put the keyboard and screen reader questions to the vendor directly, with your five minute test results attached.

While it is being fixed, keep the truly critical facts duplicated in plain sight: a one line shipping and returns summary in the open page text, not only inside a drawer. Belt and suspenders is good service design for everyone, including the sighted shopper who never opens accordions either.

Frequently asked questions

What makes an accordion accessible in one sentence?

The header is a real button that reports whether its section is expanded, the panel it controls is properly connected and hidden from all users when collapsed, and the whole thing works with a keyboard alone. If any of those three is missing, some shoppers cannot use the section.

Are tabs or accordions better for product details?

Both can be accessible when built to their standard patterns. Accordions suit product pages because they stack on mobile and let shoppers open several sections; tabs suit organized comparisons on wider layouts. Choose the one your theme implements correctly, which you can verify with the keyboard test before committing.

Can I test my accordions without a screen reader?

The keyboard pass alone catches the most common failure, headers that are not buttons. Tab to the sections, confirm a visible focus indicator, and open and close each with Enter and Space. A free screen reader adds the second layer: whether states are announced correctly. The two passes together take minutes.

Should critical information live only inside an accordion?

No. Returns windows, shipping thresholds, and safety or sizing essentials deserve a visible summary line in the open page, with the drawer holding the detail. It serves shoppers who never expand sections, on any device, and it hedges the period while an inaccessible widget awaits its fix.
