1. Visual Theme & Atmosphere

ElevenLabs' website is a study in restrained elegance — a near-white canvas (#ffffff, #f5f5f5) where typography and subtle shadows do all the heavy lifting. The design feels like a premium audio product brochure: clean, spacious, and confident enough to let the content speak (literally, given ElevenLabs makes voice AI). There's an almost Apple-like quality to the whitespace strategy, but warmer — the occasional warm stone tint (#f5f2ef, #777169) prevents the purity from feeling clinical.

The typography system is built on a fascinating duality: Waldenburg at weight 300 (light) for display headings creates ethereal, whisper-thin titles that feel like sound waves rendered in type — delicate, precise, and surprisingly impactful at large sizes. This light-weight display approach is the design's signature — where most sites use bold headings to grab attention, ElevenLabs uses lightness to create intrigue. Inter handles all body and UI text with workmanlike reliability, using slight positive letter-spacing (0.14px–0.18px) that gives body text an airy, well-spaced quality. WaldenburgFH appears as a bold uppercase variant for specific button labels.

What makes ElevenLabs distinctive is its multi-layered shadow system. Rather than simple box-shadows, elements use complex stacks: inset border-shadows (rgba(0,0,0,0.075) 0px 0px 0px 0.5px inset), outline shadows (rgba(0,0,0,0.06) 0px 0px 0px 1px), and soft elevation shadows (rgba(0,0,0,0.04) 0px 4px 4px) — all at remarkably low opacities. The result is a design where surfaces seem to barely exist, floating just above the page with the lightest possible touch. Pill-shaped buttons (9999px) with warm-tinted backgrounds (rgba(245,242,239,0.8)) and warm shadows (rgba(78,50,23,0.04)) add a tactile, physical quality.

Key Characteristics:

• - Near-white canvas with warm undertones (#f5f5f5, #f5f2ef)
• - Waldenburg weight 300 (light) for display — ethereal, whisper-thin headings
• - Inter with positive letter-spacing (0.14–0.18px) for body — airy readability
• - Multi-layered shadow stacks at sub-0.1 opacity — surfaces barely exist
• - Pill buttons (9999px) with warm stone-tinted backgrounds
• - WaldenburgFH bold uppercase for specific CTA labels
• - Warm shadow tints: rgba(78, 50, 23, 0.04) — shadows have color, not just darkness
• - Geist Mono / ui-monospace for code snippets

2. Color Palette & Roles

Primary

• - Pure White (#ffffff): Primary background, card surfaces, button backgrounds
• - Light Gray (#f5f5f5): Secondary surface, subtle section differentiation
• - Warm Stone (#f5f2ef): Button background (at 80% opacity) — the warm signature
• - Black (#000000): Primary text, headings, dark buttons

Neutral Scale

• - Dark Gray (#4e4e4e): Secondary text, descriptions
• - Warm Gray (#777169): Tertiary text, muted links, decorative underlines

Interactive

• - Grid Cyan (#7fffff): --grid-column-bg, at 25% opacity — decorative grid overlay
• - Ring Blue (rgb(147 197 253 / 0.5)): --tw-ring-color, focus ring
• - Border Light (#e5e5e5): Explicit borders
• - Border Subtle (rgba(0, 0, 0, 0.05)): Ultra-subtle bottom borders

Shadows

• - Inset Border (rgba(0,0,0,0.075) 0px 0px 0px 0.5px inset): Internal edge definition
• - Inset Dark (rgba(0,0,0,0.1) 0px 0px 0px 0.5px inset): Stronger inset variant
• - Outline Ring (rgba(0,0,0,0.06) 0px 0px 0px 1px): Shadow-as-border
• - Soft Elevation (rgba(0,0,0,0.04) 0px 4px 4px): Gentle lift
• - Card Shadow (rgba(0,0,0,0.4) 0px 0px 1px, rgba(0,0,0,0.04) 0px 4px 4px): Button/card elevation
• - Warm Shadow (rgba(78,50,23,0.04) 0px 6px 16px): Warm-tinted button shadow
• - Edge Shadow (rgba(0,0,0,0.08) 0px 0px 0px 0.5px): Subtle edge definition
• - Inset Ring (rgba(0,0,0,0.1) 0px 0px 0px 1px inset): Strong inset border

3. Typography Rules

Font Families

• - Display: Waldenburg, fallback: Waldenburg Fallback
• - Display Bold: WaldenburgFH, fallback: WaldenburgFH Fallback
• - Body / UI: Inter, fallback: Inter Fallback
• - Monospace: Geist Mono or ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas

Hierarchy

Principles

• - Light as the hero weight: Waldenburg at 300 is the defining typographic choice. Where other design systems use bold for impact, ElevenLabs uses lightness — thin strokes that feel like audio waveforms, creating intrigue through restraint.
• - Positive letter-spacing on body: Inter uses +0.14px to +0.18px tracking across body text, creating an airy, well-spaced reading rhythm that contrasts with the tight display tracking (-0.96px).
• - WaldenburgFH for emphasis: A bold (700) uppercase variant of Waldenburg appears only in specific CTA button labels with 0.7px letter-spacing — the one place where the type system gets loud.
• - Monospace as ambient: Geist Mono at relaxed line-height (1.85) for code blocks feels unhurried and readable.

5. Layout Principles

Spacing System

• - Base unit: 8px
• - Scale: 1px, 3px, 4px, 8px, 9px, 10px, 11px, 12px, 16px, 18px, 20px, 24px, 28px, 32px, 40px

Grid & Container

• - Centered content with generous max-width
• - Single-column hero, expanding to feature grids
• - Full-width gradient sections for product showcases
• - White card grids on light gray backgrounds

Whitespace Philosophy

• - Apple-like generosity: Massive vertical spacing between sections creates a premium, unhurried pace. Each section is an exhibit.
• - Warm emptiness: The whitespace isn't cold — the warm stone undertones and warm shadows give empty space a tactile, physical quality.
• - Typography-led rhythm: The light-weight Waldenburg headings create visual "whispers" that draw the eye through vast white space.

Border Radius Scale

• - Minimal (2px): Small links, inline elements
• - Subtle (4px): Nav items, tab panels, tags
• - Standard (8px): Small containers
• - Comfortable (10px–12px): Medium cards, dropdowns
• - Card (16px): Standard cards, articles
• - Large (18px–20px): Featured cards, code panels
• - Section (24px): Large panels, section containers
• - Warm Button (30px): Warm stone CTA
• - Pill (9999px): Primary buttons, navigation pills

6. Depth & Elevation

Shadow Philosophy: ElevenLabs uses the most refined shadow system of any design system analyzed. Every shadow is at sub-0.1 opacity, many include both outward cast AND inward inset components, and the warm CTA shadows use an actual warm color (rgba(78,50,23,...)) rather than neutral black. The inset half-pixel borders (0px 0px 0px 0.5px inset) create edges so subtle they're felt rather than seen — surfaces define themselves through the lightest possible touch.

7. Do's and Don'ts

Do

• - Use Waldenburg weight 300 for all display headings — the lightness IS the brand
• - Apply multi-layer shadows (inset + outline + elevation) at sub-0.1 opacity
• - Use warm stone tints (#f5f2ef, rgba(245,242,239,0.8)) for featured elements
• - Apply positive letter-spacing (+0.14px to +0.18px) on Inter body text
• - Use 9999px radius for primary buttons — pill shape is standard
• - Use warm-tinted shadows (rgba(78,50,23,0.04)) on featured CTAs
• - Keep the page predominantly white with subtle gray section differentiation
• - Use WaldenburgFH bold uppercase ONLY for specific CTA button labels

Don't

• - Don't use bold (700) Waldenburg for headings — weight 300 is non-negotiable
• - Don't use heavy shadows (>0.1 opacity) — the ethereal quality requires whisper-level depth
• - Don't use cool gray borders — the system is warm-tinted throughout
• - Don't skip the inset shadow component — half-pixel inset borders define edges
• - Don't apply negative letter-spacing to body text — Inter uses positive tracking
• - Don't use sharp corners (<8px) on cards — the generous radius is structural
• - Don't introduce brand colors — the palette is intentionally achromatic with warm undertones
• - Don't make buttons opaque and heavy — the warm translucent stone treatment is the signature

Iteration Guide

1. Start with white — the warm undertone comes from shadows and stone surfaces, not backgrounds

2. Waldenburg 300 for headings — never bold, the lightness is the identity

3. Multi-layer shadows: always include inset + outline + elevation at sub-0.1 opacity

4. Positive letter-spacing on Inter body (+0.14px to +0.18px) — the airy reading quality

5. Warm stone CTA is the signature — rgba(245,242,239,0.8) with rgba(78,50,23,0.04) shadow

6. Pill (9999px) for buttons, generous radius (16px–24px) for cards
