Implementación de técnicas de accesibilidad web: normativas, estrategias y mejores prácticas
Bibliographic record
Abstract
Web accessibility is a fundamental aspect of modern design, ensuring that websites are usable by all people, including those with disabilities. This article provides a comprehensive overview of implementing accessibility techniques in web design, focusing on key standards and best practices. It reviews the Web Content Accessibility Guidelines (WCAG), which provide an essential framework for ensuring that Web content is perceivable, operable, understandable, and robust. In addition, legal regulations such as the Americans with Disabilities Act (ADA) in the United States and the Canadian Accessibility Act (ACA), which require compliance to avoid discrimination, are addressed. The article also discusses strategies for applying these techniques, including the use of semantic HTML, color contrast optimization, and code validation. Useful tools such as WAVE, Axe, and Lighthouse are highlighted, as well as the importance of performing accessibility testing with real users to identify practical problems. Finally, case studies of successful implementations in various contexts are presented, offering practical guidance for web designers and developers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
