Visual Design Systems & Branding

Comprehensive reference for typography, color systems, spacing, component patterns, motion design, and automotive/patriotic brand identity for the Patriot Chassis e-commerce platform.

Version 1.0 February 2026 Patriot Chassis
Section 1

Typography System

A disciplined type system is the backbone of every e-commerce interface. It establishes hierarchy, guides the eye, and directly impacts readability and conversion. Every value below has been chosen to balance visual impact with accessibility requirements.

Size Scale

Element Desktop Mobile Weight
H1 (Page Title) 32 – 40px 24 – 32px 700 (Bold)
H2 (Section Heading) 24 – 32px 20 – 26px 700 (Bold)
H3 (Sub-section) 18 – 24px 16 – 20px 600 (Semi-bold)
Body 16px minimum 16 – 17px 400 (Regular)
Small / Captions 13 – 14px 13px 400 – 500
Input Fields 16px minimum 16px minimum 400
iOS Zoom Prevention
Input fields must use a minimum of 16px font-size. iOS Safari automatically zooms the viewport when a user focuses an input with a font-size below 16px, causing a jarring, broken layout experience. This is non-negotiable.

Scale Ratio

Use a 1.25x to 1.5x ratio between heading levels. For example, if H3 is 20px, H2 should be 25 – 30px and H1 should be 31 – 45px. This produces a clear visual staircase without jarring jumps or cramped levels.

Limit each page to a maximum of 4 distinct font sizes. More than four creates visual noise and weakens hierarchy.

Line Height

Context Line Height Rationale
Body text 1.5x – 1.8x Optimal readability for multi-line paragraphs
Headings 1.1x – 1.4x Tighter leading keeps headings visually compact
Buttons / Nav 1.2 – 1.3 Single-line elements need minimal but consistent leading

Line Length

The optimal reading measure is 50 – 75 characters per line (approximately 500 – 700px for body text at 16px). Lines shorter than 45 characters cause excessive line-breaking; lines longer than 80 characters cause readers to lose their place when tracking back to the next line.

Letter Spacing

Context Value Notes
Headings -0.02em Slight tightening creates a denser, more impactful look at large sizes
Body text normal (default) Font designers optimize for body-size tracking; do not override
Uppercase text 0.05em – 0.15em All-caps text looks cramped without added spacing

Fluid Typography

Use CSS clamp() to create type that scales smoothly between breakpoints without media queries. This produces a seamless reading experience from mobile to ultrawide displays.

/* Body text: 16px on mobile, scales up, caps at 20px */
font-size: clamp(16px, 1rem + 0.5vw, 20px);

/* H1: 28px on mobile, scales up, caps at 42px */
font-size: clamp(28px, 1.5rem + 2vw, 42px);

/* H2: 22px on mobile, scales up, caps at 32px */
font-size: clamp(22px, 1.25rem + 1.2vw, 32px);

/* H3: 18px on mobile, scales up, caps at 24px */
font-size: clamp(18px, 1rem + 0.8vw, 24px);
Section 2

Font Pairing for Industrial & Automotive

The Patriot Chassis brand demands typefaces that communicate strength, precision, and American manufacturing heritage. The fundamental pairing strategy is: condensed display font for headlines + clean sans-serif for body.

Recommended Display Fonts (Headlines & Titles)

Oswald — Condensed, Bold, Industrial
BUILT FOR THE ROAD AHEAD
Perfect for headlines and titles. Narrow proportions maximize impact in limited space.
Bebas Neue — Clean Condensed, All-Caps Heritage
AMERICAN ENGINEERING EXCELLENCE
Best used for large display headings and hero banners. Single weight, all-caps by nature.
Barlow Condensed — Rounded, Low-Contrast, Modern
Precision Chassis Systems
A softer condensed face with low stroke contrast. Excellent for secondary headings and navigation labels. Modern, approachable, still industrial.
Teko — Square Proportions, Strength & Stability
MODULAR CHASSIS PLATFORM
Square letter shapes evoke structural integrity and mechanical precision. Ideal for product category labels and spec callouts.

Recommended Body Font

Inter — Clean, Readable, Versatile Body Font
The Perfect Body Companion
Inter was designed specifically for screens. With tall x-height, clear letterforms, and excellent hinting at small sizes, it pairs naturally with any condensed display face. Supports 9 weights (100 – 900) and variable font rendering. This is the body font used across the Patriot Chassis site.

Recommended Pairings

Pairing Headlines Body Character
Primary (Patriot Chassis) Oswald 700 Inter 400/600 Bold, patriotic, industrial
Alternative A Bebas Neue Inter 400/600 Classic Americana, heritage
Alternative B Barlow Condensed 700 Inter 400/600 Modern industrial, approachable
Alternative C Teko 600 Inter 400/600 Technical, structural, engineering
Loading Strategy
Load display fonts with font-display: swap so text renders immediately in the fallback system font, then swaps when the custom font loads. This prevents invisible text (FOIT) and keeps Largest Contentful Paint fast. Preconnect to fonts.googleapis.com and fonts.gstatic.com.
Section 3

Color System — The 60-30-10 Rule

The 60-30-10 rule is a foundational principle from interior design that applies directly to web interfaces. It produces balanced, visually harmonious layouts without conscious effort from the viewer.

Distribution

60% Dominant
30% Secondary
10%
Proportion Role Patriot Chassis Usage
60% Dominant Backgrounds, large areas, whitespace White (#FFFFFF) and light neutrals (#f0f4f8)
30% Secondary Navigation, sidebars, headings, cards Old Glory Blue (#002868) and dark navy (#1a2332)
10% Accent CTAs, alerts, highlights, hover states Old Glory Red (#BF0A30) and its hover variant (#d40e38)

WCAG Contrast Requirements

Standard Normal Text (<18px) Large Text (≥18px bold / 24px) UI Components
WCAG AA (minimum) 4.5 : 1 3 : 1 3 : 1 vs background
WCAG AAA (enhanced) 7 : 1 4.5 : 1
Contrast Check
Always verify color combinations with a contrast checker. Our primary text color #1a2332 on white achieves a 15.7 : 1 ratio (exceeds AAA). Old Glory Red #BF0A30 on white achieves 5.5 : 1 (passes AA for normal text). Old Glory Blue #002868 on white achieves 14.5 : 1 (exceeds AAA).

American Flag & Patriotic Colors

The official colors of the United States flag are codified by multiple government agencies. Different sources use slightly different color values because no single standard covers all color models. Below are the authoritative references.

Official Color Values

Old Glory Red
PMS 193 C
HEX #BF0A30
Alt: #B31942
White
HEX #FFFFFF
RGB 255, 255, 255
Old Glory Blue
PMS 281 C
HEX #002868
Alt: #00205B

Bureau of Cultural Affairs Specification

The U.S. Department of State, Bureau of Cultural Affairs provides CMYK and RGB values that differ slightly from Pantone conversions. These are used in official government publications and diplomatic materials.

Color CMYK RGB Visual
Old Glory Blue 100 – 68 – 0 – 54 10, 49, 97
Old Glory Red 0 – 100 – 66 – 13 179, 25, 66

Patriot Chassis Brand Palette

For digital use on the Patriot Chassis website, we standardize on the following values (aligned with PMS conversions optimized for screen display):

Navy Primary
#002868
--accent-blue
Navy Light
#0A3D7F
--accent-blue-light
Navy Deep
#001A3E
Gradients, overlays
Red Primary
#BF0A30
--accent-red
Red Hover
#D40E38
--accent-red-hover
White
#FFFFFF
Backgrounds, text

Color Comparison: Source Variants

Source Red HEX Blue HEX Notes
Pantone PMS (direct conversion) #BF0A30 #002868 Most common digital conversion; used by Patriot Chassis
U.S. Web Design System #B31942 #00205B Slightly deeper values; USWDS official palette
Bureau of Cultural Affairs rgb(179,25,66) rgb(10,49,97) CMYK-derived; darker than Pantone conversions
Why the Variation?
The U.S. flag colors are officially specified only in Pantone (for fabric dye matching) and in the CMYK values from the Bureau of Cultural Affairs. There is no single official RGB or HEX value. Different conversions from PMS 193C and PMS 281C yield slightly different results depending on the color profile and rendering intent used. The values listed above are all considered legitimate representations of the flag colors for digital use.
Section 5

Spacing System

All spacing in the Patriot Chassis design system is built on an 8px base grid. Every margin, padding, gap, and dimension should be a multiple of 8. This creates a consistent visual rhythm that the human eye perceives as orderly and professional, even without consciously noticing.

Application Guidelines

Context Spacing Value CSS Token
Inline element gaps (icon + text) 8px (1x) --space-1
Form field margins 16px (2x) --space-2
Column gutters 24px (3x) --space-3
Card internal padding 16 – 24px (2x – 3x) --space-2 to --space-3
Component spacing 32px (4x) --space-4
Section vertical padding 48 – 96px (6x – 12x) --section-padding
Page-level whitespace 96 – 128px (12x – 16x) --space-12 to --space-16

CSS Custom Properties

:root {
    --space-1:   8px;    /* 1x  - tight */
    --space-2:  16px;    /* 2x  - default */
    --space-3:  24px;    /* 3x  - gutters */
    --space-4:  32px;    /* 4x  - component */
    --space-6:  48px;    /* 6x  - section (small) */
    --space-8:  64px;    /* 8x  - section (medium) */
    --space-10: 80px;    /* 10x - section (large) */
    --space-12: 96px;    /* 12x - page-level */
    --space-16: 128px;   /* 16x - hero/major break */
}
Revenue Impact of Whitespace
Amazon's internal testing found that a 10px increase in whitespace around product listings produced a 1.8% lift in revenue. Generous, consistent spacing is not just aesthetic — it has measurable commercial value. Products that breathe sell better than products that feel cramped.
Section 6

Hero Section Design

The hero section is the single most important visual element on any landing page. It establishes brand identity, communicates the primary value proposition, and drives the first action. It must work flawlessly at every viewport width.

Dimensions

Hero Type Dimensions Aspect Ratio Use Case
Full-bleed 1920 x 1080px 16 : 9 Homepage, major landing pages
Standard banner 1600 x 500px ~3.2 : 1 Category pages, product collections
Full viewport 100vw x 100vh Dynamic Immersive landing pages, brand stories
Split layout 50/50 or 60/40 (text/image) Varies Product launches, about pages

Above-the-Fold Targets

Required Elements

Every hero section must include exactly three elements:

  1. Headline — clear, benefit-driven, 6 – 12 words maximum
  2. Subheadline — supporting detail, 15 – 25 words
  3. Single primary CTA — one action, not two or three competing buttons

Live Example Pattern

Built Tough. Built American.

Custom chassis systems engineered for strength, precision, and the open road.

Explore Chassis
Product Image
Split Layout Rationale
The 60/40 split (text-heavy side larger) is preferred for Patriot Chassis because the product names are long and descriptive. The 50/50 split works better when the product image is the primary selling point and requires equal visual weight.
Section 7

Card Design Patterns

Product cards are the primary browsing interface in e-commerce. A well-structured card communicates product identity, price, and social proof (rating) within a single glance. Consistency across all cards is essential — irregular card heights or misaligned elements create a sloppy, untrustworthy impression.

Image Ratio

Use a 1:1 (square) image ratio for product cards. This is the industry standard used by Amazon, Shopify, and every major e-commerce platform. Square images are easier to crop consistently and align in grids without awkward gaps or overflows.

Content Stack (Top to Bottom)

  1. Image — square, product-centered, consistent background
  2. Title — max 2 lines, truncate with ellipsis
  3. Price — bold, red accent color
  4. Rating — star icons + review count
  5. CTA Button — "Add to Cart" or "View Details"

Card Behavior

State CSS Effect
Default box-shadow: 0 2px 8px rgba(0,0,0,0.10) Subtle elevation, card floats above page
Hover transform: translateY(-4px)
box-shadow: 0 8px 24px rgba(0,0,0,0.12)
Card lifts, shadow deepens — invites click
Transition transition: transform 0.25s cubic-bezier(0.4, 0, 0.2, 1),
  box-shadow 0.25s cubic-bezier(0.4, 0, 0.2, 1)
Smooth, natural motion with ease-out deceleration

Fixed Heights & Text Truncation

All cards in a grid must share the same total height. Use fixed image containers and truncate overflowing text. This keeps the grid visually clean and prevents layout shifts caused by variable content lengths.

.card-title {
    display: -webkit-box;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;
    overflow: hidden;
    text-overflow: ellipsis;
    min-height: 2.8em; /* Reserve space for 2 lines */
}

.card-image {
    aspect-ratio: 1 / 1;
    object-fit: cover;
    width: 100%;
}

Border vs. Shadow

Section 8

Shadow & Border System

Shadows create the illusion of depth and physical layering. A consistent shadow system with defined levels prevents the ad-hoc "just make it look elevated" approach that leads to visual inconsistency. Each level corresponds to a specific UI role.

Shadow Levels

Level 1
Subtle
Level 2
Card
Level 3
Hover
Level 4
Modal
Level CSS Value Use Case
Level 1 — Subtle 0 1px 3px rgba(0,0,0,0.08) Inputs, table rows, minimal lift. Elements that are part of the page but need slight separation.
Level 2 — Card 0 2px 8px rgba(0,0,0,0.10) Product cards, content blocks, sidebar panels. The standard "floating" element.
Level 3 — Hover / Raised 0 8px 24px rgba(0,0,0,0.12) Hover states, dropdowns, popovers. Elements that are temporarily elevated by user interaction.
Level 4 — Modal / Overlay 0 16px 48px rgba(0,0,0,0.16) Modals, dialogs, image lightboxes. The highest elevation — demands full attention.

CSS Custom Properties

:root {
    --shadow-1: 0 1px 3px rgba(0,0,0,0.08);
    --shadow-2: 0 2px 8px rgba(0,0,0,0.10);
    --shadow-3: 0 8px 24px rgba(0,0,0,0.12);
    --shadow-4: 0 16px 48px rgba(0,0,0,0.16);
}

Border Guidelines

Border Style CSS Value Use Case
Subtle divider 1px solid #e2e6ea Section separators, table borders, card edges
Blue-tinted subtle 1px solid rgba(0, 40, 104, 0.1) On-brand borders that carry a hint of navy (--border-subtle)
Red accent 1px solid rgba(191, 10, 48, 0.2) Highlight borders, active states (--border-accent)
Focus ring 2px solid #002868 + outline-offset: 2px Keyboard focus indicators for accessibility

Transition Timing

Shadow and border transitions should use 200 – 300ms duration with the standard easing function:

/* Standard easing — quick start, gentle deceleration */
transition: box-shadow 0.25s cubic-bezier(0.4, 0, 0.2, 1);

/* Shorthand using the design token */
transition: all 0.3s cubic-bezier(0.4, 0, 0.2, 1);  /* var(--transition) */
Section 9

Animation & Motion Design

Motion should be purposeful and restrained. Animation that serves no functional purpose — decorative spinners, gratuitous parallax, bouncing icons — degrades performance and annoys users. Every animated element should answer the question: "What does this motion communicate?"

Transition Durations

Interaction Duration Easing
Hover / Focus 200 – 300ms cubic-bezier(0.4, 0, 0.2, 1)
Toggle / Expand 250 – 350ms cubic-bezier(0.4, 0, 0.2, 1)
Page transitions 300 – 500ms ease-in-out
Scroll-triggered (AOS) 400 – 800ms ease (AOS default)

AOS (Animate On Scroll) Library

AOS is a lightweight (5.7KB gzipped) library for scroll-triggered animations. It is the recommended approach for entrance animations on the Patriot Chassis site.

Setting Default Patriot Chassis Standard
Offset 120px 120px (trigger point above viewport bottom)
Duration 400ms 400 – 800ms depending on element importance
Easing ease ease for most; ease-out-cubic for hero content
Once false true — animate once only; replaying on every scroll is distracting

Common AOS Effects

<!-- Fade up (most common, works everywhere) -->
<div data-aos="fade-up" data-aos-duration="600">...</div>

<!-- Fade in from left (for side-by-side layouts) -->
<div data-aos="fade-right" data-aos-duration="600">...</div>

<!-- Zoom in (for hero product images) -->
<div data-aos="zoom-in" data-aos-duration="800">...</div>

<!-- Staggered cards (delay creates cascade) -->
<div data-aos="fade-up" data-aos-delay="0">Card 1</div>
<div data-aos="fade-up" data-aos-delay="100">Card 2</div>
<div data-aos="fade-up" data-aos-delay="200">Card 3</div>

Reduced Motion Preference

Some users experience motion sickness, vestibular disorders, or simply prefer no animation. The prefers-reduced-motion media query must be respected. This is an accessibility requirement, not optional polish.

@media (prefers-reduced-motion: reduce) {
    *, *::before, *::after {
        animation-duration: 0.01ms !important;
        animation-iteration-count: 1 !important;
        transition-duration: 0.01ms !important;
        scroll-behavior: auto !important;
    }

    [data-aos] {
        opacity: 1 !important;
        transform: none !important;
        transition: none !important;
    }
}

Performance Rules

Section 10

Photography Standards

Product photography is the #1 factor in e-commerce purchase decisions. Poor images destroy trust instantly. Every product image must meet the following technical standards before publication.

Image Dimensions

Image Type Minimum Size Aspect Ratio Background
Product (primary) 2000 x 2000px 1 : 1 (square) White (#FFFFFF or #F5F5F5)
Product (fill) 85% frame fill Product should occupy 85% of the frame area
Lifestyle / In-use 2400 x 1600px 3 : 2 or 4 : 3 Natural environment
Hero background 1920 x 1080px 16 : 9 Dark / industrial setting
Thumbnails 400 x 400px 1 : 1 Same as primary (cropped)

File Formats & Compression

Format Size vs. JPEG Browser Support Use Case
WebP 25 – 34% smaller 97%+ (all modern browsers) Primary format for all images
AVIF 50%+ smaller ~90% (Chrome, Firefox, Safari 16+) Progressive enhancement with <picture> fallback
JPEG Baseline 100% Fallback for older browsers
PNG 2 – 5x larger 100% Only for images requiring transparency (logos, icons)

File Size Budgets

Image Type Maximum Size Quality Setting
Hero images Under 300KB WebP quality 80 – 85
Product images Under 200KB WebP quality 80 – 85
Thumbnails Under 100KB WebP quality 75 – 80

</picture>
Always Set width and height Attributes
Including explicit width and height on <img> elements allows the browser to calculate the aspect ratio before the image loads, preventing Cumulative Layout Shift (CLS). This is a Core Web Vital and directly impacts search ranking.
Section 11

Brand Consistency

Brand consistency is the cumulative effect of every visual decision being the same across every page, every component, and every interaction. A user should never feel like they have left the Patriot Chassis site when navigating between pages. This requires a systematic approach, not ad-hoc styling.

Design Tokens (CSS Custom Properties)

Every visual value — color, spacing, font, shadow, border, timing — must be defined as a CSS custom property and referenced throughout the stylesheet. Direct hex values or pixel numbers in component styles are prohibited.

  /* Motion */
  --transition: 0.3s cubic-bezier(0.4, 0, 0.2, 1);
}

Component Library Approach

Build a library of reusable components rather than styling pages individually. Every button, card, form element, badge, and navigation item should be a defined component with predictable behavior.

Component Consistent Properties
Buttons Same padding (14px 32px), same border-radius, same uppercase letter-spacing (0.05em), same transition timing
Cards Same border-radius (8px), same shadow level (Level 2), same hover behavior (translateY + shadow increase), same internal padding
Form inputs Same height (48px), same border style, same focus ring, same placeholder color, 16px font minimum
Section headings Same font (Oswald 700), same color (--accent-blue), same bottom border, same spacing above/below
Navigation links Same hover color, same transition speed, same active state indicator

Cross-Page Checklist

Section 12

Automotive & Industrial Visual Design

The Patriot Chassis brand operates in the automotive aftermarket / custom chassis space. The visual language must communicate strength, precision, American craftsmanship, and mechanical authority. This is not a minimalist lifestyle brand — it is an industrial brand that builds things out of steel.

Brand Personality

Attribute Visual Expression
Masculine / Rugged Dark navy backgrounds, heavy condensed typefaces, high-contrast imagery, metallic textures
American / Patriotic Red + navy + white palette, stars-and-stripes accents (used sparingly), "Built in America" messaging
Precise / Engineered Grid-aligned layouts, technical specifications prominently displayed, monospace fonts for measurements, clean lines
Powerful / Strong Bold headline weights (700+), square/angular design elements, industrial photography, dark-on-light contrast
Trustworthy / Reliable Consistent design system, professional photography, clear pricing, visible contact information

Color Application for Automotive

Dark Navy — Authority, Depth
Red — Action, Power
White

The combination of dark navy + red + white achieves a patriotic and rugged aesthetic simultaneously. Navy provides depth and authority. Red drives action and urgency. White provides breathing room and contrast. This triad is inherently American and inherently industrial.

Typography for Automotive

Bold, condensed typefaces are the standard in automotive and industrial branding. They convey strength through their dense, compact letterforms — the typographic equivalent of a steel I-beam.

Photography Direction

Product Photography

Lifestyle / Workshop Photography

Technical Imagery

Industrial Design Elements

Element Implementation Feeling
Angular dividers Diagonal SVG section breaks instead of flat horizontal lines Dynamic, forward-moving energy
Metallic gradients Subtle silver/steel gradient overlays on header backgrounds Industrial material, polished steel
Texture overlays Faint diamond-plate or brushed-metal texture at 3 – 5% opacity Workshop floor, raw material
Bold horizontal rules 4px red accent bars above or below section headings Structural, like a weld bead or accent stripe
Number callouts Large, bold statistics (e.g., "4,500 lbs rated") in display font Confidence in engineering specifications

What to Avoid
