life360.com is built on a pure-white canvas (rgb(255,255,255)). The system uses rgb(239, 239, 239) as the singular interactive color. Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside Times New Roman as the primary typeface. A restrained elevation system (1 distinct shadow) — shadows reserved for the few elements that must lift off the page. Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

Do's & Don'ts

12 enforceable rules pulled verbatim from the spec

Use the extracted shadow patterns for elevation — they are tuned to match the brand palette

Use Off-White (`#efefef`) as the primary accent — it's the brand's signature interactive color

Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes

Style form inputs with a `2px inset rgb(118, 118, 118)` border — use border-based inputs, not floating labels or underline-only

Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room

Each card includes a left image — imagery is part of the card identity, not optional

Don't

Don't invent new shadow values — use only the extracted shadow levels

Don't introduce additional saturated accent colors — the palette is intentionally controlled

Don't over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners

Don't remove the input border — the border is the primary affordance indicator for form fields

Don't make the nav sticky — this design lets it scroll away to maximize content focus

Don't put a CTA button in the nav — this design uses links only at the top
