WCAG, or Web Content Accessibility Guidelines, set standards for making web content accessible. Published by W3C’s Web Accessibility Initiative in 1999, the guidelines have undergone multiple updates. Designers can utilize a WCAG-based checklist for accessibility, including establishing appropriate contrast ratios for text and UI components. Maintaining focus visibility is essential for navigation by keyboard and assistive technology users. Additionally, interactive elements must have sufficient size to ensure easy engagement, particularly on touch devices.
Web Content Accessibility Guidelines (WCAG) established by W3C set the international standard for making web content accessible to individuals of all abilities.
To enhance accessibility, ensure contrast ratios for text vs. background meet minimum standards: normal text at least 4.5:1, and large text at least 3:1.
Making focus visible assists keyboard and assistive-technology users. Visually highlighting the focused element aids navigation on interfaces.
Interactive elements should have a minimum size of 24 pixels to ensure users can easily interact with them on touch devices.
