The presentation of information in HTML files is desirably en hanced by the use of one or more separate scripting Javascript.TM. files, referenced from the HTML file, which uses information presented as variables in the HTML file. In this manner, a high degree of formatting flexibility can be achieved, while reducing the likelihood of errors in the HTML pages, improving ease of site maintenance, and standardising the "look and feel" of the site. Improvements in the network bandwidth required to browse sites organised in this manner can also be achieved in favourable instances.
