    Mobile Compatibility

    Viewport & Responsive Test

    Tests how well your website works on mobile devices. Checks viewport configuration, responsive layout, touch targets, font readability, and simulates rendering across different screen sizes.
    C
    65/100
    Mobile Friendly1 breakpoint
    Viewport Meta
    The viewport meta tag tells mobile browsers how to scale the page. Without it, mobile devices render at desktop width.
    Responsive Design
    Uses CSS media queries or flexible layouts to adapt content to different screen sizes automatically.
    Touch Icons
    Apple touch icons and favicons displayed when users add the site to their home screen on mobile devices.
    Readable Font Size
    Base font size should be at least 16px on mobile to ensure text is readable without zooming.
    Relative Units
    Using em, rem, %, or vw instead of fixed px values allows content to scale properly across screen sizes.
    No H-Scroll Risk
    No elements wider than the viewport that would cause horizontal scrolling on mobile devices.
    Tap Targets OK
    Interactive elements (buttons, links) are at least 48x48px with enough spacing to prevent accidental taps.
    No Fixed Widths
    No elements with fixed pixel widths that could overflow on smaller screens and break the layout.

    ❌ Critical: 12px body text is too small. Minimum 14px, recommend 16px+.

    ✅ Optimal line spacing: 1.50 ratio (ideal range 1.4–1.6).

    ⚠️ Partial contrast: 0 elements below WCAG AA threshold (min 4.2:1).

    ❌ Missing H1: Every page should have exactly one H1 element for SEO and accessibility.

    ✅ Strong hierarchy: Headlines are 2.3x larger than body text.

    ✅ Lean font stack: 1 font families keeps load times fast.
