Accessibility has become a growing influence on design and UX today. Apps operate on more devices that are not a tablet or phone. This impacts services that physically-impaired and visually-impaired consumers use, as well as expands the application of assistive tech aids.
Markup code elements in apps and websites influences the quality of accessibility features for physically- and visually-impaired users. When markup is planned with user experience in mind, accessibility needs can be addressed alongside analytics tags.
