Website Accessibility Compliance
Website accessibility is something that is overlooked a lot of the time by companies and organizations building their website. Title III of the Americans with Disabilities Act requires that businesses and nonprofit services providers make accessibility accommodations so that the disabled public have access to the same material as others. Examples of how to make a website compliant would be adding captions to videos, adding audio descriptions, creating links to videos instead of only embedding, ensuring that the page does not contain repeating flashing images or strobe effects, including a 'skip navigation' button, among others things.
