# CeylonNikah Design System

## Overview

CeylonNikah describes itself as: “Premium Muslim Matrimonial Platform in Sri Lanka.” The interface is light, built on **White (#FFFFFF)** with **Deep Blue (#1E293B)** text, and **Teal (#83A79D)** as the main accent.

Type is set in **Bricolage Grotesque** and **Plus Jakarta Sans**, with **ui-monospace** for code. Headlines run large with tight negative tracking; body text is 14px. Depth comes from soft drop shadows. Controls are pill-shaped.

Measured from [ceylonnikah.lk](https://ceylonnikah.lk/) on November 7, 2026 at 1440×900 and 390×844 from 358 rendered elements. Values are computed styles from the live page, not the original source files.

## Typography

**Bricolage Grotesque**, **Plus Jakarta Sans** and **ui-monospace** (monospace) share the interface. Fallback stack: `Bricolage Grotesque, Plus Jakarta Sans, system-ui, -apple-system`.

- **headline-display:** Bricolage Grotesque 48px at weight 900, line height 1, tracking -0.025em (30px on mobile). Page title (h1).
- **headline-lg:** Bricolage Grotesque 36px at weight 700, line height 1.11 (24px on mobile). Section headings (h2).
- **body-md:** Plus Jakarta Sans 14px at weight 400, line height 1.43. Body text.
- **body-sm:** Plus Jakarta Sans 12px at weight 400, line height 1.63. Secondary and small text.
- **caption:** Plus Jakarta Sans 10.5px at weight 400, line height 1.63. Captions and fine print.

- **code:** ui-monospace 14px at weight 700, line height 1.43, tracking 0.025em. Code and technical values.

## Layout

Spacing does not follow a strict grid: 56% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 8px, md 10px, lg 32px, xl 40px.
- **Sections:** 80px vertical padding between major sections.
- **Gaps:** 24px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1280px.
- **Page margin:** 32px on each side of full-width sections.
- **Breakpoints:** 600px, 640px, 768px, 1024px, 1280px, 1400px, 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(0, 0, 0, 0.05) 0px 1px 2px 0px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.1) 0px 8px 10px -6px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(6, 78, 59, 0.2) 0px 10px 15px -3px, rgba(6, 78, 59, 0.2) 0px 4px 6px -4px`

Hairline rings and inset highlights also appear: `rgb(255, 255, 255) 0px 0px 0px 0px, rgba(52, 211, 153, 0.3) 0px 0px 0px 1px, rgba(0, 0, 0, 0) 0px 0px 0px 0px`.

## Shapes

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

- **sm (12px):** 220 elements.
- **full (9999px):** 160 elements.
- **md (16px):** 32 elements.
- **lg (24px):** 28 elements.

## Components

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

- **button-primary (“Colombo”):** #064E3B80 fill, #D1FAE5 text, 12px/600, 12px radius, padding 8px 12px, border 1px solid #10B98133.
- **button-primary-hover:** background #047857CC, text #FFFFFF on hover.
- **button-secondary (“Instant Auto-Fill & Register”):** transparent fill, #FFFFFF text, 14px/700, 16px radius, padding 12px 0px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(6, 78, 59, 0.2) 0px 10px 15px -3px, rgba(6, 78, 59, 0.2) 0px 4px 6px -4px`.
- **button-outline (“95%”):** #D1FAE5E6 fill, #065F46 text, 10px/900, 9999px radius, padding 4px 10px, border 1px solid #6EE7B7.
- **button-ghost (“සිංහල”):** transparent fill, #334155 text, 12px/700, 12px radius, padding 4px 10px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FFFFFFE6, #FFFFFFF2, #F0FDFA, #F8FAFC.
- Do keep text in 4 levels: #1E293B, #0F172A, #334155, #475569.
- Do reserve #83A79D for primary actions and key highlights.
- Do set headlines in Bricolage Grotesque with tight tracking (-0.025em).
- Do reuse the measured spacing steps (8px, 10px, 32px).
- Do make buttons and chips fully rounded (9999px); most other elements use 12px corners.
- Don't introduce new font families beyond Bricolage Grotesque, Plus Jakarta Sans and ui-monospace.
- Don't use #83A79D for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.15s, 0.3s, 0.2s. Longer ambient animations run 1s, 2s.

- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `cubic-bezier(0, 0, 0.2, 1)`, `cubic-bezier(0.4, 0, 0.6, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
