FP98: FrontPage Editor Deletes Unknown Attributes in HTML

When the FrontPage Editor parses HTML, there are certain tags for which unknown attributes are discarded.

FrontPage normalizes HTML to the HTML 2.0 specification (RFC 1866), or, where the 2.0 specification is superceded, to the HTML 3.2 proposal.

If you want to write HTML with unknown attributes to tags identified in the "More Information" section of this article, put the entire tag into an HTML Markup section.

To insert an HTML Markup section, follow these steps:

1. On the Insert menu, click FrontPage Component.
2. In the Select A Component list, click HTML Markup.
3. Click OK.
4. Type the HTML you want and then click OK.

The FrontPage Editor knows about a certain set of attributes for each HTML tag it can write. FrontPage Editor preserves these known attributes. You can manipulate them using dialog boxes and direct manipulation in the HTML Markup dialog box in FrontPage 98. When the FrontPage Editor encounters an attribute it does not recognize, it attempts to put that attribute and its value into the extended attribute list for that tag. Any tag for which the FrontPage Editor preserves extended attributes will include an Extended button in its Properties dialog box. The attribute list is preserved by the FrontPage Editor in its extended attributes list for that tag and is inserted into the final HTML.

Not all tags have extended attribute lists in FrontPage. The following HTML tags do not have an extended attribute list in FrontPage Editor: When you work with these tags, unrecognized attributes are discarded by the FrontPage Editor.
