Code BEAM London 2026 - UX/UI Design Improvements

Overview

Comprehensive redesign and optimization of the Code BEAM London conference website, focusing on design consistency, accessibility, performance, and user experience.

🎨 1. Design System & Color Consolidation

Problems Fixed:

45 unique color values scattered across codebase with no organization
Critical semantic mismatches: .btn-orange was actually green (#4DBA12)
$light-blue variable was actually purple (#543462)
Three different green hex values (#4DBA12, #4eb913, #4EB813) used inconsistently
Named CSS colors (blue, purple, gray, grey) causing inconsistent rendering

Solution:

Created _sass/_variables.scss - Centralized design system with:

Brand Colors

$brand-green: #4DBA12;     // Primary (consolidated 3 variants)
$brand-cyan: #12E7FE;      // Secondary
$brand-magenta: #e32dfd;   // Accent
$brand-orange: #ee5a30;    // Actual orange color

Semantic Color System

50+ properly named color variables
Grayscale from $gray-50 to $gray-950
Purple family ($purple-darkest to $purple-light)
Functional colors ($text-light, $link-color, $nav-bg, etc.)

Typography Scale

Font families reduced from 7 to 2 (Montserrat & Lato)
Responsive font sizes using rem units
Standardized font weights and letter spacing

Spacing Scale

$spacing-xs: 4px
$spacing-sm: 8px
$spacing-md: 16px
$spacing-lg: 24px
$spacing-xl: 32px
$spacing-2xl: 48px
$spacing-3xl: 64px
$spacing-4xl: 96px
$spacing-5xl: 128px

Standardized Breakpoints

$breakpoint-xs: 480px   // Small phones
$breakpoint-sm: 640px   // Large phones
$breakpoint-md: 768px   // Tablets
$breakpoint-lg: 1024px  // Laptops
$breakpoint-xl: 1280px  // Desktops

🔧 2. Fixed Semantic Naming Issues

Button Class Corrections

Before:

.btn-orange
  border: solid .1em #4DBA12  // Green, not orange!
  color: #4DBA12

After:

.btn-green
  border: solid .1em $brand-green
  color: $brand-green
  
// Legacy support maintained
.btn-orange
  @extend .btn-green

Variable Corrections

Before:

$primary: blue;              // Named color - unpredictable
$light-blue: #543462;        // Actually purple!

After:

$primary: $brand-green;
$light-blue: $purple-base;   // Clearly documented as legacy

✨ 3. Enhanced Button UX

Improvements:

Smooth transitions - All state changes animated (300ms ease-in-out)
Hover states - Subtle lift effect with box shadow
Focus states - Visible outline for keyboard navigation (accessibility)
Active states - Click feedback with translateY
Better contrast - All buttons meet WCAG AA standards

Example:

.btn-outline
  transition: $transition-all
  cursor: pointer
  &:hover
    transform: translateY(-2px)
    box-shadow: $box-shadow-md
  &:focus
    outline: 2px solid $brand-cyan
    outline-offset: 2px
  &:active
    transform: translateY(1px)

Before:

Scrollable vertical menu (unusual UX)
No backdrop or visual separation
Awkward overflow behavior

After:

Slide-out drawer from right side
Smooth animation (300ms transition)
Dark backdrop with 70% opacity
Touch-friendly larger tap targets (1em padding)
Scrollable content for long menus
Hover states for better feedback

.nav (mobile)
  position: fixed
  right: -100%              // Hidden offscreen
  height: 100vh
  width: 80%
  max-width: 320px
  transition: right 300ms
  
  &.active
    right: 0              // Slides in

🖼️ 5. Hero Section Improvements

Problems Fixed:

Excessive logo min-height (500px) created too much whitespace
Fixed padding didn’t scale responsively
Awkward spacing on tablets

Solutions:

.logo
  min-height: 350px         // Was: 500px
  max-height: 450px         // Prevents oversizing
  object-fit: contain       // Maintains aspect ratio
  
@media (max-width: 1112px)
  min-height: 280px
  
@media (max-width: 634px)
  min-height: 220px

Responsive Padding:

Desktop: 8em 3em → 8em $spacing-2xl (48px)
Tablet: 6em $spacing-lg (24px)
Mobile: 5em $spacing-md (16px)

🎭 6. Visual Variety - Alternating Sections

Problem:

Every section used identical dark background (#000101), creating visual monotony

Solution:

.section
  background-color: $bg-section-primary
  
  &:nth-of-type(even)
    background-color: $bg-section-secondary  // Slightly lighter

Colors:

Primary: #000101 (pure black)
Secondary: #0a0f0d (subtle dark green-gray)

Creates subtle visual separation without being jarring.

⚡ 7. Performance Optimizations

Font Loading

Before: 7 font families, 6 separate HTTP requests

<link href="...Montserrat:100,200,300,400,500,600,700">
<link href="...Kaushan+Script">
<link href="...Lato:400,700,400italic,700italic">
<link href="...Karla:400,400i,700">
<link href="...Droid+Serif:400,700,400i,700i">
<link href="...Roboto+Slab:400,100,300,700">

After: 2 families, 1 HTTP request, Google Fonts v2 API

<link href="...Montserrat:wght@200;300;400;500;600;700&family=Lato:ital,wght@0,400;0,700;1,400;1,700&display=swap">

Savings: ~70% fewer font files, faster page load

Script Loading

Changed all analytics/tracking scripts to async:

Google Tag Manager → <script async>
Moment.js → defer attribute
GetResponse Analytics → async
LeadFeeder → async injection

Impact: Non-blocking page load, faster First Contentful Paint

♿ 8. Accessibility Improvements

Keyboard Navigation
- All buttons have visible :focus states
- Focus outline uses brand color (cyan #12E7FE)
- 2px outline with 2px offset for clarity
Color Contrast
- All text/background combinations reviewed
- Buttons use high-contrast hover states
- Links clearly distinguishable
Touch Targets
- Mobile menu items: 1em padding (min 44x44px)
- Buttons: 0.5em padding with large font size
- All interactive elements meet WCAG minimum
