Foundations: landmarks
Most websites have common areas of content like a header and footer, a main content area, and one or more navigation blocks. Sighted people can identify these areas based on the way they're styled and the content they contain, but people who are blind cannot do that quite as efficiently. Landmarks, like headings and lists, offer screen reader users a more comparable experience for identifying and navigating between different areas of content.
Foundations: headings
Well structured content helps everybody understand and navigate documents. When coded properly in the HTML, headings, lists, and landmarks help people who use screen readers (software that reads what’s on screen) both scan and navigate pages.
Foundations: text descriptions
Text descriptions are primary content, and when images do not have a text description, anyone who cannot see the image will not know its purpose. This means people may be unable to access content or perform related tasks.
