33 landmarks
Critical::
No <main> landmark found
Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
Info::
8 <nav> landmark(s) found
Warning::
4 of 8 <nav> elements are unlabeled
Multiple navigations need aria-label to distinguish them for screen readers.
Warning::
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
BANNER header NAV MAIN (missing!) ASIDE CONTENTINFO footer

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

Why this matters

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Learn more ▾

The <main> element marks the page's primary content area. Assistive tech offers a 'jump to main' shortcut — but only if <main> exists. Without it, every page navigation forces re-reading the header. Wrap your primary content in a single <main>.

Source: WAI-ARIA / WCAG 2.4.1

Multiple navigations need aria-label to distinguish them for screen readers.

Why this matters

Some <nav> elements lack aria-label — screen-reader users hear 'navigation' multiple times with no way to distinguish them.

Learn more ▾

When a page has multiple <nav> regions (primary, footer, breadcrumb), each needs aria-label or aria-labelledby. AT users navigate by landmark; identical 'navigation' announcements force them to enter each one to discover purpose.

Source: WAI-ARIA Authoring Practices

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.

Mobile-Readable Font Sizes
93% of visible text renders at >= 12 CSS px (16 below threshold)
REVIEW
93% of visible text renders at >= 12 CSS px (16 below threshold)
Info::
16 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> 11.0px ("NHẠC SĨ"); <span> 11.0px ("NHẠC SĨ"); <span> 11.0px ("NHẠC SĨ"); <span> 11.0px ("NHẠC SĨ"); <span> 11.0px ("NHẠC SĨ").

Heading Text Quality
1 heading-text-quality issue(s) detected
PASS
1 heading-text-quality issue(s) detected
Info::
2 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.

Placeholder text disappears on focus and is not a reliable label.

<input type="text" id="hopam-input">

Why this matters

Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).

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.
