Accessibility

Last updated: 6 October 2026

We want this site to be usable by as many people as possible, including those using a screen reader, a keyboard alone, magnification, or a browser set to reduce motion.

What we have done

The site targets WCAG 2.1 level AA. It was checked by self-assessment, not by an external audit.
Every page is reachable and operable with the keyboard alone, and the focused element is always visible.
Headings, landmarks, lists and form labels are marked up so a screen reader can announce them correctly.
Text colours were chosen to meet the AA contrast ratio against their background, in both the light and the dark view.
Text reflows down to 320 pixels wide and can be enlarged to 200% without loss of content.
Images that carry meaning have text alternatives; the technical drawings carry a title and a description. Decoration is hidden from assistive technology.
Nothing moves, blinks or plays on its own except the scroll-driven drawings, and those stop when the operating system asks for reduced motion.
An accessibility panel on every page lets you enlarge the text, raise the contrast, underline links, switch to a plainer typeface and turn animation off. Your choice is remembered.

Known limitations

The technical drawings convey their detail visually. Each has a text description, but a drawing is still a drawing — where a drawing carries something essential, the same information is written out in the text beside it.
The scroll-driven assembly on the home page needs scrolling to advance. With reduced motion enabled it becomes an ordinary block with the drawing complete and all steps listed.

Tell us

If something on this site blocks you, we want to hear it — it is treated as a defect, not as a suggestion. Write to info@zetoson.com or use the Contact form, and say which page and what happened. We aim to reply within five working days.
