Design and Accessibility: Part V

Navigation, Usability, and Accessibility

In the previous article on Design and Accessibility, Linda demonstrated the importance of separating style from structure, or how to use CSS (Cascading Style Sheets) to replace some structural layout – like the use of tables – in HTML/XHTML documents. While some designers may fear how their designs might appear to viewers who access the Internet with older browsers, this fear is ungrounded; the trend today is to allow sites to degrade gracefully in older user agents. In other words, it’s ok to allow your site to appear as plain text to someone who hasn’t or who won’t upgrade their equipment, as this degeneration (read: simplification) allows users with disabilities as well as the general public to access your online content.

Although the user may be able to access your home page, will he or she have access to the rest of your site? Navigation is one link (no pun intended) which ties style to structure and content, so navigation and a comparison to architectural “wayfinding” methods are the topics for this week’s article. Navigation is tied to accessibility and usability as well, since sites aren’t navigable if they aren’t accessible or usable.

Overview

Hypertext, Hypermedia, and just plain Hyper

We live in an age where globalization has become apparent on several levels – witness global economics, global warming, and global travel. While many globalization issues remain contentious, it seems ludicrous to view the Internet as anything other than a global communications tool since it’s based on the “World Wide” Web (W3). Although many Web authors realize that their site(s) are viewed by global audiences, the same authors/designers might not realize that their content might be restricted from view by short-sighted use of simple navigational tools and an understanding of global structure.

For instance, if you could travel back in time (and the Internet allows you to do this), you could view a copy of the very first Web page created in 1989 by Tim Berners-Lee, the man who started the W3 project at CERN (Conseil Europeen pour la Recherche Nucleaire, translated as “European Particle Physics Laboratory,” located in Geneva, Switzerland):

Linda Goin

Linda GoinLinda Goin carries an A.A. in graphic design, a B.F.A. in visual communications with a minor in business and marketing and an M.A. in American History with a minor in the Reformation. While the latter degree doesn't seem to fit with the first two educational experiences, Linda used her 25-year design expertise on archaeological digs and in the study of material culture. Now she uses her education and experiences in social media experiments.

Accolades for her work include fifteen first-place Colorado Press Association awards, numerous fine art and graphic design awards, and interviews about content development with The Wall St. Journal, Chicago Tribune, Psychology Today, and L.A. Times.
