• Designing Beneath the Surface of the Web

  Sarah Horton · 2006 · Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper reframes web accessibility as fundamentally a source code design problem, arguing that designers focus almost exclusively on the visual "surface" of web pages — colors, typography, layouts — while neglecting the underlying code layer that determines how well pages are…
