# ChargeHive EV Design System

## Overview

ChargeHive EV describes itself as: “Find EV charging stations near you, share your home EV charger and earn, or request roadside assistance. Use ChargeHive EV on Android or the web.” The interface is dark, built on **Deep Blue (#06131F)** with **Cool Mist (#EEF1F5)** text, and **Teal (#54D6CF)** as the main accent.

Type is set in **Instrument Serif** and **Manrope**, with **JetBrains Mono** for code. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Controls are pill-shaped.

Measured from [chargehiveev.com](https://www.chargehiveev.com/) on November 4, 2026 at 1440×900 and 390×844 from 495 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 16 roles, plus gradient stops #9FD23A, #C3F24C, #ED762E, #F3A15F.

## Typography

**Instrument Serif**, **Manrope** and **JetBrains Mono** (monospace) share the interface. Fallback stack: `Instrument Serif, Instrument Serif Fallback, Georgia, Times New Roman`. Other loaded fonts: Inter, Space Grotesk.

- **headline-display:** Instrument Serif 72px at weight 400, line height 0.94, tracking -0.04em (43px on mobile). Page title (h1).
- **headline-lg:** Manrope 64px at weight 600, line height 1, tracking -0.04em. Section headings (h2).
- **headline-md:** Manrope 57.5px at weight 600, line height 1.04, tracking -0.035em (36.5px on mobile). Sub-section headings.
- **headline-sm:** Manrope 36px at weight 600, line height 1, tracking -0.035em. Card and feature titles.
- **title-lg:** Manrope 32px at weight 500, line height 1.25, tracking -0.025em. Small titles.
- **body-md:** Manrope 16px at weight 400, line height 1.5. Body text.

- **code:** JetBrains Mono 11px at weight 400, line height 1.38, tracking 0.02em. Code and technical values.

## Layout

Spacing is mostly on a 4px grid (89% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 20px, xl 64px.
- **Sections:** 128px vertical padding between major sections.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 672px.
- **Page margin:** 40px on each side of full-width sections.
- **Breakpoints:** 359px, 380px, 639px, 640px, 641px, 768px, 1023px, 1024px, 1100px, 1280px, 1536px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(195, 242, 76, 0.35) 0px 0px 0px 1px, rgba(195, 242, 76, 0.55) 0px 10px 30px -10px`
- `rgba(195, 242, 76, 0.45) 0px 0px 14px 0px`
- `rgba(0, 0, 0, 0.2) 0px 2px 12px 0px`

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 124 elements.
- **sm (12px):** 80 elements.
- **xs (9px):** 32 elements.
- **md (14px):** 32 elements.
- **lg (16px):** 28 elements.
- **xl (20px):** 20 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“CHARGING”):** #54D6CF fill, #F4F6F3B8 text, 10px/500, 50% radius, padding 0px.
- **button-secondary (“GET THE APP →”):** transparent fill, #101D1C text, 11.5px/800, 999px radius, padding 0px 6px 0px 24px, shadow `rgba(237, 118, 46, 0.2) 0px 10px 26px 0px`.
- **button-outline (“GET THE APP →”):** #08182294 fill, #F6F8F5 text, 11px/700, 999px radius, padding 0px 6px 0px 18px, border 1px solid #FFFFFF29.
- **button-ghost (“CHARGING”):** transparent fill, #F4F6F3B8 text, 10px/500, padding 0px.
- **input-field (“Try Telangana or Maharashtra”):** #00000033 fill, #EEF1F5 text, 14px/400, 12px radius, padding 0px 16px, border 1px solid #FFFFFF26.
- **card:** transparent fill, #F8FAFC text, 16px/400, padding 24px 0px 0px 0px, border 1px solid #FFFFFF1A.
- **link:** transparent fill, #E2E8F0BD text, padding 0px.

## Do's and Don'ts

- Do use #06131F for the page and lift surfaces in small steps: #050912, #101D1C.
- Do keep text in 4 levels: #EEF1F5, #F8FAFC, #A9B1BA, #818C8F.
- Do reserve #54D6CF for primary actions and key highlights.
- Do set headlines in Instrument Serif with tight tracking (-0.04em).
- Do reuse the measured spacing steps (8px, 16px, 20px).
- Do make buttons and chips fully rounded (9999px); most other elements use 12px corners.
- Don't introduce new font families beyond Instrument Serif, Manrope and JetBrains Mono.
- Don't use #54D6CF for large backgrounds or body text.
- Don't make interface transitions slower than 0.32s.

## Motion

Interface transitions are quick: 0.18s, 0.3s, 0.32s, 0.14s. Longer ambient animations run 0.9s, 1.1s.

- **Easing:** `cubic-bezier(0.22, 1, 0.36, 1)`, `cubic-bezier(0.2, 0.7, 0.1, 1)`, `cubic-bezier(0.4, 0, 0.2, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
