jsMath: A Method of Including Mathematics in Web Pages
The jsMath package provides a method of including mathematics in HTML pages
that works across multiple browsers under Windows, Macintosh OS X, Linux
and other flavors of unix. It overcomes a number of the shortcomings of
the traditional method of using images to represent mathematics: jsMath
uses native fonts, so they resize when you change the size of the text in
your browser, they print at the full resolution of your printer, and you
don't have to wait for dozens of images to be downloaded in order to see
the mathematics in a web page. There are also advantages for web-page
authors, as there is no need to preprocess your web pages to generate any
images, and the mathematics is entered in TeX form, so it is easy to create
and maintain your web pages.
Although it works best with the TeX fonts installed, jsMath will fall back
on a collection of image-based fonts (which can still be scaled or printed
at high resolution) or unicode fonts when the TeX fonts are not available.
There is a control panel connected to a small floating button that lets the
user select which fallback method to use or change some other settings like a
scaling factor to use for the mathematics compared to the other text on the
page.

The jsMath package is based on the TeX mathematics layout engine as
described in Appendix G of Donald Knuth's The TeXbook. Since jsMath
uses the TeX fonts, it also has the font metric information from the
associated .tfm files at its disposal, so it handles italic correction and
kerning in essentially the same way as TeX. This makes the output of jsMath
as nearly identical to that of TeX as I could manage.
JsMath does not use MathML, but this is not intended to indicate that
MathML is not a good or useful thing, because it is, and I know that. But
MathML is not designed to be written directly by human beings, and I wanted
a format that I could easily write by hand and include in quick,
non-archival web pages like homework assignments, while not having to
require students to use a particular browser or download extra software to
be able to view it. At the time I wrote jsMath, only Mozilla on the PC
implemented MathML directly, and MSIE on the PC could do it with a plugin,
but there wasn't a Mac-based browser that handled MathML adequately (it
looks like Mozilla 1.5 might finally have it working), and I'm not sure
what the situation is for unix. I wanted a solution that worked
out-of-the-box with a wider range of browsers, and on the Mac in particular
since that is what I use. Thus jsMath was born.
