All too often, accessibility doesn’t cross a designer’s mind when creating user interfaces. Overlooking accessibility considerations in the design phase can trickle down through to your website or application and have a large impact on your users. Whether it is usability testing, creating prototypes, adopting an accessible pattern library, or even just annotating wireframes, designers must incorporate accessibility into their workflow. Instead of overloading QA engineers to find accessibility defects, thinking of accessibility from the start, or “shifting left,” can have a tremendously positive impact on the content you create.
