Guide to good practices for WWW authors
See the HTML 2.0 DTD for further details on the use of these elements.
Most HTML elements are defined by a start and end tag. A tag consists of the element name, in the case of the start tag enclosed within the signs "<" and ">", and in the case of the end tag, enclosed within the signs "</" and ">", e.g. <H1> </H1> The start tag may also include attributes which are given in the form "attribute_name=value", e.g. <IMG ALIGN=MIDDLE>. Some elements, indicated in this list with an asterisk, are empty, that is, they have a start tag only and no end tag.

Proposed extensions in HTML 3.0 support tables, text flow around inline figures, equations and formulae, customised lists, fine positioning control, horizontal tabs and horizontal alignment of headers and paragraph text, static banner area, use of the LINK element to provide standard toolbar/menu items for navigation, use of the NOTE element for admonishments and footnotes. Forms are extended to support graphical selection menus, file upload and audio input; the user will be given a higher level of interactivity with Web pages through scripting of forms and other methods. More layout control will be given to authors through the option of style sheets.
HTML 3.0 will provide the option of style sheets which give substantial control over presentation of documents while still conforming to the standard. The style sheets proposal is evidence of the increasing recognition of the fact that authors want to exercise the sort of control over formatting and layout which HTML as a simple markup language can never provide. Basically the proposal provides for the linking of an HTML document to a specific style sheet, enabling authors to define the look of a document fairly precisely. Formatting and layout instructions are incorporated in the style sheet, rather than the document itself.
