Accessibility Capabilities: Post-Source Code and Content

This document examines the trade-offs and benefits of dynamic accessibility remediations applied to web content. A systematic approach is used to evaluate numerous atomic functional capabilities ranging from alternative text and personalized visual presentation to interactive components. The outcome of the trade-offs and benefits evaluation is cross-referenced to WCAG for each capability. Each capability is also assessed for automation based on the presence of programmatically recognizable patterns conducive to automated adaptation. The technological approaches considered include the same HTML, CSS, and JavaScript-based adaptations commonly used today achieving in-source accessibility, but implemented dynamically in content delivery pipelines and browser extensions, all without requiring additional on-screen widgets. Management and maintenance concerns, as well as forward-looking capabilities, are addressed using the same systematic trade-offs and benefits approach. A closing discussion articulates our human-centered design principles and an appendix clarifies responsibilities across the ecosystem.
