Accessibility

What this site does

• Works without JavaScript. Every page, including search, works with scripting turned off. Only the Share button and the cookie banner need it, and a page without it loses nothing else.
• Keyboard navigable throughout, with a “skip to content” link as the first focusable element on every page and a visible focus indicator on every interactive element.
• Structured headings and landmarks, in a sensible order, so a screen reader can move through a page section by section — and the navigation announces which part of the site you are in.
• Labelled controls. The search field has a proper label; the Share button announces the result out loud rather than only changing its own text; and in the cookie banner, refusing is as easy to reach as accepting and comes first.
• Reflow and zoom. Layout is fluid to a single column with no fixed pixel widths. The one wide element — the comparison table — scrolls inside its own container rather than pushing the page sideways.
• No motion. There are no animations, carousels, autoplaying media or movement of any kind, so there is nothing for a reduced-motion preference to suppress.

What has actually been tested, and what has not

Being specific about this matters more than a compliance badge. WCAG 2.2 Level AA is the design and testing baseline; it is a target here, not a certified result.

• Tested: automated accessibility checks on every page before it is published, heading structure and order on every kind of page, keyboard access to navigation and search, and colour contrast throughout.
• Not yet tested: a full manual screen-reader pass over every kind of page, and testing with people who use assistive technology. Neither has been done, and this page will say so until they have.

Known limitations

• The comparison table is a genuine data table and is wide. It scrolls horizontally inside its own region on a narrow screen, which works but is more effort than reading it on a wide one.
• Some property values carry technical qualifications — a measurement condition, a phase, an axis — shown as text beside the value. They read in the right order, but they are dense.
• There are no photographs on the site yet, so there is no missing image description to find. That is an absence rather than an achievement, and it will need attention when pictures arrive.

Telling us about a problem

If something here is unusable, please say so — including which page, what happened, and what format or adjustment would help. Write to hello@hekno.co.uk, or see contact and corrections. We treat an accessibility problem as something broken, not as a suggestion.

Accessibility statement

We aim to make this site usable by as many people as reasonably possible. We design and test against WCAG 2.2 Level AA, while recognising that what the law requires comes from the law rather than from WCAG alone.

That means keyboard navigation, a visible focus indicator, structured headings, labels a screen reader can announce, sufficient contrast, zoom and reflow, no unnecessary motion, clear error messages, cookie controls anyone can operate, and alternatives for media.

We will always name the limitations we know about rather than claim a compliance we cannot support, and we check this site by automated means, by keyboard, and by reading it — paying most attention to the pages people actually use.

For accessibility feedback, or to ask for a reasonable adjustment, write to hello@hekno.co.uk telling us the page, the problem, and the format or adjustment that would help.
