Everything that you see on this page and any web page is actually generated by computer code known as HTML. This code not only contains the text that you see but also instructions on how the page should look - layout and formatting.
Generally, most pages are readable by most people; however, there are significant numbers of the population who have some difficulty reading web pages as they are. Eyesight is the most common area of difficulty but fortunately web pages give us ways to make our pages accessible to many with these difficulties. We do have to use them though!
Using Styles in a document is one of the easiest things you can do. Not only do they ensure consistency in text formatting (e.g. font size, italic, bold, etc.) but they help people to navigate through a page. Styles set a hierarchy of information on the page both for visual and non-visual readers. You can access styles from the format menu or by using the keyboard shortcut of Ctl-1 (or 2,3,4).
