# Hashnode — Style Reference
> Architectural blueprint on white marble. Light, precise, and structured, guiding builders through their thoughts.

**Theme:** light

**Site:** https://hashnode.com

Hashnode's design evokes a sense of organized clarity, like a refined environment where complex ideas are constructed. Predominantly bright, near-white surfaces create a spacious, focused canvas, punctuated by sharp, technical typography and a singular, vibrant blue accent. Precision is communicated through crisp sans-serif lines, defined component boundaries, and minimal, intentional softening at corners, creating a sense of professional purpose.

## Layout

The page adheres to a max-width 1176px contained layout, centered on the screen, creating a focused content experience. The hero section features a split layout: prominent text on the left, a contained vector illustration on the right, resting on a subtly gradiented background. Content sections follow a consistent vertical rhythm with 48px gaps. Article listings use a grid layout where each item is a minimal card, emphasizing content over heavy visual decoration, laid out side-by-side. Navigation is handled by a sticky left sidebar containing primary links and a 'what's new' popout, alongside a conventional top bar for global actions and status.

## Imagery

The visual language for imagery is a mix of abstract, rounded vector illustrations and tightly cropped product screenshots or contextual photography. Illustrations are colorful but contained within defined shapes with soft, rounded corners (e.g., the hero illustration). Photography in article previews tends to be full-bleed within the card's image container, sometimes black and white or vibrant. Icons are primarily functional Font Awesome Pro, supplemented by more decorative Font Awesome Jelly for specific brand elements. Imagery serves a dual role: decorative atmosphere in hero sections and explanatory content/contextual previews within listings. Image density is moderate; sections are image-rich but not image-dominant.

## Guidelines

### Do

- Use suisseIntl (Inter) color Charcoal Black (#16191c) for all primary body text at 16px, lineHeight 1.5, letterSpacing 0.05em.
- Apply Electric Indigo (#1d52de) only to primary interactive elements like 'Start your blog' buttons or active navigation links.
- Implement Card borders using Border Silver (#d1d4d9) at 1px for subtle visual separation, primarily for the 'What's New' style cards.
- Maintain a clear visual hierarchy, using Charcoal Black (#16191c) for main headings and Carbon Slate (#1c2024), Ash Mist (#7b8187) for subtext and metadata.
- Utilize Cloud White (#f9fafb) as the dominant background color for content areas, creating a clean, focused environment.
- Ensure input fields and interactive elements default to a 10px border-radius, aligning with the site's general component rounding.
- Apply a consistent layout max-width of 1176px for main content areas, with a section vertical gap of 48px to create breathing room.

### Don't

- Do not introduce new saturated accent colors outside of Electric Indigo (#1d52de); maintain a largely achromatic palette.
- Avoid excessive use of shadows; the design relies on subtle borders and background color changes for separation, not pronounced drop shadows.
- Do not use highly rounded elements except for specific pill-shaped components like badges (radius 1.67772e+07px); most elements should use 10px or 14px radius.
- Do not use overly bold or decorative typography for headings; suisseIntl (Inter) at various weights should convey authority through clarity, not visual loudness.
- Avoid tight spacing between major sections; larger gaps like 48px are crucial for readability and information compartmentalization.
- Do not deviate from the specified suisseIntl letterSpacing values (-0.025em for larger text, 0.05em for smaller) as they are critical to the font's precise appearance.
