However, key principles were explained, and sources of further information or documentation were provided. These instruct the browser to perform certain actions, either concerning how text is displayed, or whether an image or another document should be loaded. This means that the original text file tends to look very different from document when viewed with a browser. These tags can be inserted in the text by hand, or special HTML editors can be used. Until recently most of these inserted the tags to achieve the various effects, but another program was needed to see the effect.
Later editors attempt to display the effect and hide the tags from the user.
As the secretarial staff given the job of HTML editing for this project both used Wordperfect on the PC, it made sense that they should use its integral editor. Before it was introduced, however, it was felt that the concept behind HTML editing needed to be explained, so that they would be able to create satisfactory HTML documents without a special editor. The first training session was devoted to this. Subsequent sessions introduced the Wordperfect editor, but for a number of reasons, both staff preferred raw HTML editing. The HTML Editor was set up to default to the server's root directory, making editing and installation a seamless process.
