While creating website content it is crucial to consider accessibility. There are a few basic steps that should be followed in order to assure your content is accessible:
Add built-in Headings to document and do not skip numbers (e.g. jumping from Heading 1 to Heading 3)
Use built-in List options (e.g. bullets or numbers)
Add Alt Text for links
Add Alt Text for images
Define Table Headers and simplify Tables as much as possible
