Accessibility

Our aim

AsOf is a public record, and it should be readable by everyone, whatever device, browser or assistive technology they use. We build the site to the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.

What the site does

• Every page can be used with a keyboard alone, starts with a link that skips to the content, and shows a clear outline on whatever has focus.
• Pages are built from headings, landmarks, lists and real tables with header cells, so a screen reader can move through them by structure.
• Text and controls meet AA contrast in both the light and the dark theme, and the theme can follow your system or be set at the foot of any page.
• A claim's status is always said in words (valid, unverified, disputed, superseded), never by colour alone.
• Every chart has a text alternative that lists its values.
• Text can be zoomed to 200% and pages reflow to a narrow window without sideways scrolling; wide tables scroll inside their own region.
• The one animation, a loading pulse, stops when your system asks for reduced motion.
• The one keyboard shortcut, / to reach the search box, can be turned off at the foot of any page.
• Most pages have a markdown version (add .md to the address) with the same content as plain text.

Known limits

• Labels inside charts become small on a narrow phone. The chart's values are in its text alternative, and on a fact page in the list of dated values below it.
• Pages we link to as sources are published by others and may not be accessible.
• Passages quoted from sources are shown in their original language and wording.

How it is tested

We test the site ourselves; it has not been audited by an outside body. Each kind of page is checked with the axe-core rule set for WCAG 2.2 A and AA, at phone and desktop widths, in the light and dark themes (the script is e2e/a11y.mjs in the site's code), and reviewed by hand with a keyboard. Automated checks find only some barriers, so reports from readers matter.

Report a barrier

If something on AsOf is hard or impossible for you to use, or you need information from the record in another form, write to hello@chroniclabs.co. Tell us the page address, what you were trying to do, and the browser and assistive technology you use. A person reads every report.
