Mobile-Readable Font Sizes

Action

81% of visible text renders at >= 12 CSS px (5 below threshold)

REVIEW

81% of visible text renders at >= 12 CSS px (5 below threshold)

5 text node(s) render below 12 CSS pixels on mobile

Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <span> 9.0px ("Chugoku"); <span> 9.0px ("Hikikomori"); <span> 9.0px ("Kyokai"); <span> 11.0px ("CHK"); <span> 11.0px ("CHK").

Landmark Structure

9 landmarks

PASS

9 landmarks

<main> landmark present

1 <nav> landmark(s) found

Skip navigation link is missing (WCAG 2.4.1)

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Page Structure — as a screen reader sees it

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

Learn more ▾

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

Heading Text Quality

1 heading-text-quality issue(s) detected

PASS

1 heading-text-quality issue(s) detected

6 heading(s) are all-uppercase (excluding short acronyms)

Headings rendered in all-uppercase are a styling choice that should be done via CSS (`text-transform: uppercase`), not by typing the text in caps. Capitalized text is read letter-by-letter by some screen readers (e.g., "H-E-L-L-O W-O-R-L-D" instead of "hello world"). It's also a soft signal of CMS-migration artifacts where the original lowercase intent was lost.

Got: 6 all-caps heading(s)

Lighthouse Accessibility Audits

Score 95/100 — 2 failing, 17 passed

PASS

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

Contrast

Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements

These are opportunities to improve the legibility of your content.

Visible text labels that do not match the accessible name can result in a confusing experience for screen reader users. Learn more about accessible names.
