Hyperlatex supports the two "official" standards for HTML, namely
HTML 2 and HTML 3.2. The command \htmllevel determines which
kind of HTML will be generated. Legal values for the argument are
html2 and html3.2.
The default is currently html3.2, which is understood by most
current browsers. However, this is subject to change without notice,
so if you want to generate a given HTML level, then include the
\htmllevel command in your document!
The setting of the \htmllevel has influence on the
following concepts:
HTML 2 HTML 3.2 changing type-size X sub- & superscripts X tables X centering X
Note that the optional argument of \htmlrule
and \htmlimage allows you to add arbitrary
attributes that may violate the standard that you have chosen with
\htmllevel. The same may be true if you use
\htmlattributes.
