    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.
    D
    49/100
    Not Mobile Friendly
    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.
    Viewport
    width=100%; initial-scale=1; maximum-scale=1; minimum-scale=1; user-scalable=no;

    ❌ Critical: 11px body text is too small. Minimum 14px, recommend 16px+.

    ⚠️ Wide line spacing (1.82). 1.4–1.6 is optimal for body text.

    ✅ Optimal line length: ~50 chars/line (ideal 45–75 CPL).

    ✅ WCAG AA contrast: All text meets 4.5:1 ratio (min 5.9:1).

    ⚠️ Minor heading issue: 1 level skip(s) detected. Maintain sequential order for screen readers.

    ⚠️ Weak hierarchy: Headlines should be ≥2x body size for clear visual structure.
