jaytel.com — Design System
1. Visual Theme & Atmosphere
Jaytel is a product company that designs like one. The interface is clean, structured, and confident — a white canvas with a single electric-blue accent that does all the heavy lifting. The palette is professionally restrained: off-whites, a thorough grey scale from #F7F7F7 to #333, and one chromatic colour (#2B47FF) that appears on every interactive surface.
System-ui is the chosen typeface — a deliberate choice to feel native to the OS, reducing friction and increasing perceived trustworthiness. At small sizes, system-ui’s optical properties match the platform’s own UI, making Jaytel’s interface feel like it belongs in the same ecosystem as the tools it supports.
The layout uses a named grid system with CSS custom properties for columns, gaps, and responsive span patterns. Transitions use a custom spring easing curve, giving interactions a physical feel rather than a linear snap.
2. Color Palette & Roles
Neutrals — the foundation:
| Role | Token | Value | Notes |
|---|---|---|---|
| Page background | --theme-background / --color-white |
#ffffff |
|
| Surface / cards | --theme-surface / --color-off-white |
#F3F3F3 |
Slight warmth |
| Subtle bg | --color-grey-50 |
#F7F7F7 |
Hover states |
| Dividers | --color-grey-100 |
#eeeeee |
|
| Secondary text | --color-grey-200 / --theme-text-secondary |
#BABFC5 |
|
| Label / tertiary | --color-grey-500 / --theme-text-tertiary |
#73808C |
|
| Mid text | --color-grey-600 |
#595959 |
|
| Strong text | --color-grey-700 |
#333333 |
|
| Primary text | --theme-text-primary / --color-black |
#000000 |
Pure black |
| Off-black | --color-off-black |
#0f0f0f |
High contrast alt |
Accent — the only colour:
| Role | Token | Value | Notes |
|---|---|---|---|
| Brand / CTA | --color-primary / --theme-accent |
#2B47FF |
Electric blue |
| Hover accent | --color-primary-dark / --theme-link-hover |
#245EFF |
Slightly deeper |
| Light blue tint | --color-light-blue |
#c5d3dd |
Muted, for info states |
The accent is assertive. It appears on buttons, links, labels, and CTAs. Everything else is achromatic — this contrast makes the blue feel like a system signal rather than decoration.
3. Typography Rules
Single typeface: system-ui (OS-native sans-serif). No web font loaded — this is an intentional performance and authenticity decision.
| Role | Size | Weight | Line Height | Tracking |
|---|---|---|---|---|
| H2 (section heading) | 24px | 400 | 27.6px (1.15×) | −0.16px |
| Body / dialogs | 16px | 400 | normal | normal |
The type scale is minimal in what was captured — system-ui adapts to whatever the OS renders. Weight 400 is used throughout; differentiation comes from size and colour. No bold headings, no heavy display type — this keeps the interface feeling calm and functional rather than promotional.
Notable: no custom display or serif layer exists. The brand voice is expressed through layout and the accent colour, not typographic personality.
4. Component Stylings
Primary Buttons
- Background:
--theme-button-background(#2B47FF) - Text:
--theme-button-text(#ffffff) - Hover:
--color-primary-dark(#245EFF) - Spring easing transition on all interactive state changes
Links
- Default:
--theme-link(#2B47FF) - Hover:
--theme-link-hover(#245EFF) - Navigation links use
--color-grey-200(#BABFC5) — deliberately muted
Cards / Elevated surfaces
- Background:
--theme-l2-background(#ffffff) - Shadow:
drop-shadow(0px 20px 32px rgba(0,0,0,0.1)) - Hover shadow:
drop-shadow(0px 2px 4px rgba(0,0,0,0.05))— shadow reduces on hover (card “settles”)
Labels
- Default:
--theme-label(#73808C) - Accented:
--theme-label-accent(#2B47FF)
Borders
--theme-border:#BABFC5— same as secondary text, consistent mid-grey
5. Layout Principles
Jaytel uses a named CSS grid system:
--grid-columns: 8 columns--grid-gap: 16px--grid-width: 100vw- Responsive span tokens:
--span-centered-xs/sm/med/lrg/full— all set to1 / -1(full-width on all viewports, suggesting content constrains internally)
Spacing scale is extensive, running from --spacing-0 (2px) through --spacing-256 (16rem), providing fine-grained control over padding and margins.
Breakpoints:
- Tablet:
752px - Desktop:
1145px
The layout philosophy is constrained-width content blocks centered within a full-width grid, with generous spacing at the macro level.
6. Depth & Elevation
Two-tier shadow system using CSS filter: drop-shadow (not box-shadow):
| Level | Usage | Value |
|---|---|---|
| L2 resting | Cards, panels | drop-shadow(0px 20px 32px rgba(0,0,0,0.1)) |
| L2 hover | Same cards on hover | drop-shadow(0px 2px 4px rgba(0,0,0,0.05)) |
The inversion — large shadow at rest, small shadow on hover — suggests cards are in an elevated “floating” default state that settles closer to the surface when interacted with. This is an uncommon and sophisticated interaction pattern.
Page background and surface (#F3F3F3) provide a one-step tonal foundation beneath card whites.
7. Do’s and Don’ts
Do:
- Use
#2B47FFexclusively for interactive and branded elements — one accent, used consistently - Apply system-ui for the native-platform feel; don’t substitute a web font
- Use the card shadow inversion on hover — it’s a signature interaction
- Leverage the full grey scale semantically:
#BABFC5for secondary,#73808Cfor labels,#000for primary - Use the spring easing curve for all transitions to maintain physical feel
Don’t:
- Introduce a second accent colour — the single-blue system is non-negotiable
- Make navigation links prominent; they are intentionally muted (
#BABFC5) - Use box-shadow — the system uses
filter: drop-shadowexclusively for cards - Go below 752px grid assumptions without testing the 8-column layout
- Use font weights above 400 for body — restraint is the tone
8. Responsive Behavior
Explicit breakpoints:
- Mobile: below 752px
- Tablet: 752px+
- Desktop: 1145px+
Grid span tokens suggest all content spans full width at mobile/tablet, constraining only through internal padding. The 8-column grid resolves to a single flow at smaller viewports.
The touch targets on buttons (padded with #2B47FF fill) are adequately sized. System-ui scales crisply across all display densities. No font-size scaling tokens detected — sizes remain fixed across breakpoints.
9. Agent Prompt Guide
Quick reference:
- Backgrounds:
#ffffff(page),#F3F3F3(surface),#F7F7F7(subtle) - Text:

#2B47FF(all interactive) - Font: system-ui, 400 weight throughout
- Grid: 8 columns, 16px gap, 752px / 1145px breakpoints
Prompt to replicate this aesthetic:
“Design a SaaS product interface using system-ui at 400 weight. White background,
#F3F3F3surface. Single accent#2B47FFfor all buttons and links. Navigation links are muted#BABFC5. Cards havedrop-shadow(0px 20px 32px rgba(0,0,0,0.1))at rest that reduces on hover. All transitions use spring easing.”
Prompt to extend a component:
“Create a feature card for jaytel.com. White background with
drop-shadow(0px 20px 32px rgba(0,0,0,0.1)). Label in#73808Csystem-ui 400. Heading in#000000. Body text#333. CTA link in#2B47FF. On hover, shadow reduces todrop-shadow(0px 2px 4px rgba(0,0,0,0.05)).”
