1. Official Web Accessibility Statement (WCAG 2.2 Level AA)

Berlo Desarrollos holds an unyielding commitment to ensuring its digital platforms, web applications, and customer tools are universally accessible and inclusive to all individuals, regardless of physical, sensory, cognitive, or technological abilities.

Our software engineering conforms rigorously to the Web Content Accessibility Guidelines (WCAG 2.2) published by the W3C WAI initiative, while complying with the European Accessibility Act (EU Directive 2019/882 / EAA 2025), the Americans with Disabilities Act (ADA Title III), and Section 508 standards.

Technical Conformance Measures Implemented on berlo.dev:

  • 100% Keyboard Operability: All interactive elements, command docks, modal dialogs, and forms feature a logical tab order (tabindex) and visible high-contrast focus rings.
  • Direct Skip Navigation Link: A native #main-content skip link accessible on first tab strike, allowing screen reader and keyboard users to bypass top navigation.
  • Semantic HTML5 & Strict ARIA: Unambiguous heading hierarchies (single h1, h2, h3), clear landmark roles (header, nav, main, footer, dialog), and live feedback announcements via aria-live for NVDA, JAWS, and VoiceOver.
  • Elevated Contrast Ratios: Text content exceeds the mandatory 4.5:1 ratio for regular copy and 3:1 for large display headings across both dark and light modes.
  • Descriptive Text Alternatives: Contextual and descriptive alt attributes on all informative media, with explicit aria-hidden="true" exclusion for decorative background elements.
  • Respect for User System Preferences: Native support for prefers-reduced-motion (suppressing animations for users with vestibular sensitivities) and persistent high-contrast settings.
Rejection of Superficial Accessibility Widgets:

We strictly reject third-party accessibility overlays and widget plugins that claim automated compliance while interfering with native assistive tech. Real accessibility is engineered directly into clean, semantic source code.

2. Digital Sustainability & Web Eco-Design (Green Web)

The digital technology ecosystem accounts for approximately 4% of global greenhouse gas emissions — surpassing commercial aviation. At Berlo Desarrollos, we believe state-of-the-art engineering must be inherently resource-efficient and sustainable.

We adhere to the Sustainable Web Manifesto (Clean, Efficient, Open, Honest, Regenerative, and Resilient) through strict eco-design standards:

Concrete Digital Decarbonization Actions:

  • Radical Byte Reduction (Green Coding): We build with pure Vanilla JavaScript and native CSS tokens, bypassing megabytes of heavy frontend libraries. This reduces wire transfer payload by up to 80% compared to typical corporate sites.
  • Server Energy Optimization: Hardened Apache server configuration with mod_deflate/GZIP compression, minimal concurrent roundtrips, and aggressive browser caching resulting in 0 grams of CO₂ transfer on repeat views.
  • Next-Gen Lightweight Media: Scalable vector graphics (SVG), optimized WebP formats, and native lazy loading (loading="lazy") that prevents unnecessary data and battery drain on mobile networks.
  • Dark Mode by Default: Dark pixels on modern OLED and AMOLED displays consume up to 60% less battery energy than bright white displays.

3. Continuous Audit & Direct Accessibility Feedback

Accessibility and ecological efficiency are not static milestones, but ongoing engineering disciplines.
