# Dev BD IT Design System

## Overview

Dev BD IT describes itself as: “Professional WordPress Web Designer and Developer specializing in Elementor, Crocoblock, Digital Marketing and SEO. Let’s build a high-converting website.” The interface is light, built on **White (#FFFFFF)** with **Near Black (#000000)** text, and **Green (#59C21C)** as the main accent.

Type is set in **Roboto** and **Plus Jakarta Sans**. Headlines run large; body text is 16px. The surface language is flat. Corners are mostly 12px.

Measured from [devbdit.com](https://devbdit.com/) on November 6, 2026 at 1440×900 and 390×844 from 318 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 14 roles.

- **White (#FFFFFF):** Page background, seen 1 time. Token `background`, CSS `--iti-dropdown-bg`.
- **Near Black (#000000):** Primary text and headings, seen 24 times. Token `on-surface`.
- **Cool Slate (#54595F):** Secondary text, seen 2 times. Token `on-surface-variant`.
- **Warm Slate (#736666):** Muted text and metadata, seen 2 times. Token `on-surface-muted`.
- **Slate (#737373):** Subtle text and placeholders, seen 18 times. Token `on-surface-subtle`.
- **Snow (#FDFDFC):** Raised areas one step from the page, seen 3 times. Token `surface-container-low`.
- **Snow (#F4FBF0):** Cards and panels, seen 1 time. Token `surface-container`.
- **Mist (#F3F3F1):** Hover and pressed fills, seen 3 times. Token `surface-container-high`.
- **Pale Green (#E1F5D6):** Highest raised elements, seen 47 times. Token `surface-container-highest`.
- **Warm Gray (#B1AAAA):** Borders and dividers, seen 1 time. Token `outline`.
- **Green (#59C21C):** Primary buttons and calls to action, seen 39 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Deep Blue (#001D39):** Accent (CSS variable). Token `secondary`.
- **Dark Orange (#985E23):** Accent (CSS variable). Token `tertiary`.

## Typography

**Roboto**, **Plus Jakarta Sans** and **system-ui** share the interface. Fallback stack: `Roboto, sans-serif`.

- **headline-display:** Roboto 72px at weight 600, line height 1 (26px on mobile). Page title (h1).
- **headline-lg:** Roboto 47px at weight 600, line height 1 (22px on mobile). Section headings (h2).
- **headline-md:** Plus Jakarta Sans 28px at weight 600, line height 1.2. Sub-section headings.
- **headline-sm:** Roboto 24px at weight 600, line height 1. Card and feature titles.
- **body-md:** system-ui 16px at weight 400, line height 1.5. Body text.
- **body-lg:** Plus Jakarta Sans 18px at weight 500, line height 1.5. Lead paragraphs.
- **body-sm:** Roboto 12px at weight 400, line height 1.5. Secondary and small text.
- **label-lg:** Plus Jakarta Sans 16px at weight 600, line height 1.25. Large buttons and tabs.
- **label-md:** Roboto 15px at weight 500, line height 1. Buttons, navigation and labels.
- **label-sm:** Roboto 14px at weight 600, line height 1.2. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 60% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 2px, sm 8px, md 12px, lg 24px.
- **Sections:** 80px vertical padding between major sections.
- **Gaps:** 20px is the most common gap in flex and grid layouts.
- **Breakpoints:** 479px, 480px, 575px, 576px, 767px, 768px, 991px, 992px, 1024px, 1199px, 1200px, 1360px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#FDFDFC → #F4FBF0 → #F3F3F1 → #E1F5D6) and #B1AAAA borders.

## Shapes

Most elements use 12px corners. Measured radii, most used first:

- **sm (12px):** 204 elements.
- **md (18px):** 24 elements.
- **lg (22px):** 12 elements.

## Components

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

- **button-primary (“Hire Me”):** #59C21C fill, #FFFFFF text, 13px/600, 12px radius, padding 12px 24px.
- **button-outline (“View Portfolio”):** #F4FBF0 fill, #000000 text, 16px/600, 12px radius, padding 15px 25px.
- **link:** transparent fill, #737373 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FDFDFC, #F4FBF0, #F3F3F1, #E1F5D6.
- Do keep text in 4 levels: #000000, #54595F, #736666, #737373.
- Do reserve #59C21C for primary actions and key highlights.
- Do reuse the measured spacing steps (8px, 12px, 24px).
- Do use 12px corners on most elements; larger surfaces also use 18px and 22px.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond Roboto, Plus Jakarta Sans and system-ui.
- Don't use #59C21C for large backgrounds or body text.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.3s, 0.4s, 0.5s. Longer ambient animations run 300s.

- **Easing:** `ease`.
