Mobile UI Snippets — Free HTML CSS JS Mobile App Screen Examples

These snippets recreate native mobile patterns in the browser, framed inside a CSS phone mockup so they are immediately presentable in a portfolio, a pitch deck or a design review. Chat threads, social feeds, onboarding flows, banking dashboards, music players, camera views, checkout screens and settings lists.

The individual pieces — bottom sheets, tab bars, action sheets, pull-to-refresh, swipeable rows — are also usable on their own in any responsive web app, mockup frame removed.

The phone frame is one wrapper, not a constraint

Every screen renders inside a pure-CSS device frame — a rounded rectangle with a notch or status bar and consistent proportions — that is entirely decorative and lives in a single wrapper element. That separation matters practically: delete the wrapper and the screen underneath is a normal responsive layout, which is why several of the components here, particularly the sheets and tab bars, are written to work identically with or without the frame around them.

Interaction patterns borrowed deliberately, not copied blindly

A bottom sheet that can be dragged closed, a tab bar with an active-state indicator, an action sheet that slides up from the bottom edge — these are patterns users already know from native apps, and reproducing their exact feel (the drag resistance, the spring-back, the backdrop dimming) is what makes a web recreation read as familiar rather than approximate. Getting the small physics details right is most of the work; the visual chrome is comparatively easy.

Safe areas are not optional on a real device

A layout that ignores env(safe-area-inset-bottom) will put an interactive control directly under an iPhone's home indicator or a notch's rounded corner the moment it runs as an actual installed or full-screen web app rather than inside a demo frame. These snippets reserve that space explicitly, which only becomes visible as a real requirement once a screen leaves the mockup and runs on hardware.

Touch targets sized for fingers, not cursors

Every tappable control here is at least 44 by 44 CSS pixels with spacing from its neighbours, even when the visible icon inside it is smaller — the hit area extends beyond what is drawn. That gap between visible size and tappable size is deliberate: an icon can look small and refined while still being comfortably tappable, but only if the two are sized independently.
