Making your interfaces accessible is important, as everyone should be able to have equal access to information. Krug recommends a few easy things to do to learn more about accessibility and how you can implement it. The first tip he mentions is to fix the usability problems that confuse everyone. If there is a common thing that confuses most people who use your interface, it will very likely confuse others who have accessibility issues. Therefore, it’s important to test your interface often and fix the parts that confuse everyone. The second tip is to read articles that go over how people use screen reader software/adaptive technology. This will help you understand how to make things useful, as you learn how the technology works. The third tip is to read a book about web accessibility, and laws and regulations related to that. The last tip is to make simple common accessibility fixes to your interface. This includes adding alt text to every image, use the right headings for titles, subheadings, etc. You should also make sure your forms work with screen readers, add a “skip to main content” button on each page, make content accessible by keyboard, add contrasting colors between your text and background, and use an accessible website template (if you use something like WordPress to make your website).
