According to the CDC, 22% of adults in the United States are living with a disability. Therefore, it’s important that we ensure our web content is accessible and inclusive for everyone. The Web Accessibility Initiative (WAI) has developed a set of guidelines to set the foundation for accessible web content. The Web Content Accessibility Guidelines (WCAG), these guidelines have 4 main principles which are Perceivable, Operable, Understandable, and Robust (POUR).
