A button may meet technical accessibility requirements, however does its label make sense when learn aloud? Display reader testing uncovers these gaps, permitting you to repair issues earlier than they influence actual customers.
So, who’s accountable for display reader testing? Everybody. Creating accessible web sites is a crew effort. Builders should guarantee semantic code and correct ARIA roles. Designers should suppose past visuals, specializing in clear navigation and intuitive layouts. QA groups should combine display reader checks into their workflows, validating varieties, navigation, and dynamic content material. Even venture managers and stakeholders play a job by prioritizing accessibility from the beginning.
Getting Began: Selecting a Display Reader
