Maintaining Context

Given the small screen area, a user can become easily lost. Headings are often not in view, and the user, if distracted by other work, can lose a sense of context. Style sheets can help maintain this sense of context through color. The <div> and <span> tags are intended to provide page designer-defined content-based style. By defining classes of <div> tags with various colors and border styles, the designer provides additional information. However, a significant number of people suffer from some form of color blindness. Thus, it may be necessary to design pages both with and without using color styles.
