HTML Help Viewer 5.3.2 - Supported Tags
This document describes the subset of HTML supported by Help.
<!-- -->
Comment. All tags and text within the comment are
ignored by HTML Help.
<A>
Help fully supports the HREF and NAME attributes, except that:
- Links to other files can only be relative, not absolute. So
HREF="..\foo.htm" works but HREF="C:\foo.htm" does not
- Double quotation marks "" must always be put around filenames
and bookmarks e.g. HREF="foo.htm" but not HREF=foo.htm
- references to web and email addresses are ignored.
- DOS-style (8.3) filenames should be used.
<B>
Bold text is displayed in bright white.
<BODY>
Indicates the beginning of the text to be displayed.
<BR>
Line break.
<CODE>
Code is just displayed as Bold text (in bright white).
<EM>
Emphasised text, like italicised text, is displayed using
the color magenta (a shade of purple).
<H1>
Help puts this header 1 text in bold and puts a thick line
underneath it.
<H2>,
<H3>
Header 2 and 3 text is put in bold, and a new paragraph is started.
<HEAD>
HTML header.
<HR>
Creates a horizontal rule along the screen. Only a horizontal rule without
any attributes is supported at present.
<HTML>
Denotes a HTML file.
<I>
Italicised text is displayed using the color magenta
(a shade of purple).
<LI>
A list object.
<OL>
At present, ordered lists are rendered as unordered lists. Embedded lists
are not supported.
<P>
New paragraph.
<PRE>
Preformatted text
<STRONG>
Strong text, like bold text, is displayed as bright
white.
<TITLE>
Does nothing - yet.
<TT>
TT text, like italicised text, is displayed using
the color magenta (a shade of purple).
<UL>
Embedded lists are not currently supported.
Over 250 character entities are supported, including all Latin-1 entities.
NCRs (Numeric Character References) and UTF-8 are also supported. However,
help can only display those characters that are available in the currently
active DOS codepage. For a list of codepages that help is 'aware' of,
type "HELP /C" at the command prompt.
- Text is wrapped if it does not fit on the line.
- Tags are case insensitive, so
<A HREF="FOO.HTM"> is equivelent to
<a href="foo.htm">.
- The maximum size for a document is 64K.
- Only short (8.3) file names are supported.
- Help distinguishes between file types by filename
extension. Therefore the .htm extension is recommended for HTML files.
