FIX

Theme color only

Theme-color present but no dark variant

A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.

Got: #2563eb

Consider adding CSS with @media (prefers-color-scheme: dark) and <meta name='color-scheme' content='light dark'>.

Detection limited to meta tags and inline styles

Mobile-Readable Font Sizes

90% of visible text renders at >= 12 CSS px (13 below threshold)

REVIEW

90% of visible text renders at >= 12 CSS px (13 below threshold)

13 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> 11.5px ("PLATAFORMA DE ESTUDOS INTELIGENTE"); <span> 10.9px ("ESTUDANTES"); <span> 10.9px ("REVISÕES FEITAS"); <span> 10.9px ("QUESTÕES RESPONDIDAS"); <span> 10.9px ("GRUPOS ATIVOS").

Landmark Structure

5 landmarks

PASS

5 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.

Iframe Accessibility

1/2 iframe(s) missing title; 0 placeholder(s)

PASS

1/2 iframe(s) missing title; 0 placeholder(s)

WCAG 4.1.2: iframes need a title attribute so screen readers can announce what's embedded. Without one, the announcement is just "iframe" -- the user has no way to decide whether to enter or skip.

Manifest has no maskable icon

Android 12+ Adaptive Icons crop non-maskable icons to a circle or squircle -- frequently hiding important parts of the logo. Add at least one icon entry with `"purpose": "maskable"` (or `"any maskable"`) and a maskable-aware design (16% safe-zone padding around the inner mark).

Browser-chrome `theme-color` meta tag present

The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.
