Every part page, table and form here works by keyboard alone, and where it does not, the phone does.

We call the site partly conformant. Most of it meets AA; a few items in section 05 do not yet. We would rather say that than claim full conformance and have you find the gap on a Friday afternoon with a bike in pieces.

This statement covers xervilo.com: the catalogue, the seven part group pages, the three by-bike pages, the chain calculator, the inquiry form, the chat widget and the legal pages.

• A skip link is the first thing Tab reaches on every page.
• The Catalogue menu opens with Enter or Space, and Escape closes it. Below 1024 pixels it becomes a full-height drawer with the same behaviour.
• Every focusable element shows a gold outline at least 2 pixels thick.
• Buttons, links and form controls are at least 44 by 44 pixels, so they are hittable with a thumb or a trembling hand.
• Each form field has a visible label. Errors appear in text next to the field, not only as a red border, and say what to fix: "Give us a phone number or an email, one is enough."
• Body text on cream measures above 12:1 contrast. Oxblood headings on cream measure above 10:1.
• Text can be zoomed to 200 percent and the layout reflows to one column without sideways scrolling, down to a 320 pixel screen.
• Every photograph has alt text describing the part in it. Icons next to text are hidden from screen readers so labels are not read twice.
• The cookie bar does not block the page or trap focus.

Chain width, freehub standard, ISO bead-seat diameter and clamp diameter tables are built with table headers and captions, so a screen reader announces "11-speed, 5.5 mm" as a row, not as loose numbers. On a narrow screen a wide table scrolls inside its own box and can be reached and scrolled with the keyboard.

The chain length calculator uses labelled number inputs with their units written beside them. When the link count changes, the result is announced. An out-of-range value, say a 600 mm chainstay, shows an error in text under the field. The formula, L = 2C + F/4 + R/4 + 1, is written out on the page so you can do the sum by hand if you prefer.

The running strips of part names on the home page pause on hover and when anything inside them has keyboard focus. With reduced motion turned on, they stop completely and the names wrap into a still list. Headings that slide in on scroll appear in place instead. There is no autoplay video and nothing flashes.

Each page is checked with keyboard only, with NVDA on Windows and VoiceOver on iPhone and Mac, at browser zoom of 200 and 400 percent, and at widths of 320, 360, 414, 768, 1024, 1440 and 1920 pixels. Automated checkers run as well, but they miss things a person catches in a minute, like a focus order that jumps from the form to the footer.

Call +1 (565) 555-2353 Monday to Friday and read us the speed count and wheel size, or just describe the bike. Email [email protected] with whatever you have; a photo of the rear dropout answers half our questions. We can also send any page of this site, including the terms and privacy policy, as plain text by email.
