HTML 4.0 Online

Welcome to HTML 4.0 Online. HTML 4.0 Online is a tour of the major features defined by the HTML 4.0 recommendation. You can either walk through the tour in order by following the navy links at the bottom of each page, or you can navigate to different topics using the outline to the left.

HTML 4.0 is currently supported by Internet Explorer 4.0 and includes major improvements such as richer form controls for grouping (<FIELDSET>) and labeling elements (<LABEL>), HTML buttons (<BUTTON>), improved tables, script, and style support. All of these new elements plus the existing ones will be covered on your tour.

Before we begin, it is important to understand what HTML 4.0 is and what HTML 4.0 is not. HTML 4.0 recommends the appropriate markup you should use when authoring a document. HTML 4.0 does not define how a document should be displayed (it does provide suggestions), and it does not define how a document is manipulated by scripting languages such as JavaScript or VBScript. Instead HTML 4.0 provides a way to include style and script in your document. The style or appearance of the document is defined using CSS (cascading style sheets), and the object model for manipulating the page is still being defined by the W3C's Document Object Model Working Group.

The next page starts the tour by explaining the different types of HTML documents that HTML 4.0 defines. There are actually 3 DTD's or document type definitions, defined by HTML 4.0. Each page you author should identify what HTML DTD it is being based on.
