Many states were concerned with design criteria or guidelines for WWW sites. This concern over the appearance of Web pages surfaced with greater focus and clarity in the more recent policies and encompasses such topics as "look and feel," consistency from agency to agency, and useful navigation aids. These policies ranged from many specific rules that must be applied to all sites to very general guidelines that left implementation up to individual agencies. The very specific policies tended to require certain design features and detailed programming methods for the creation of Web sites.
