I apologize for the limited browser and platform audience for this website.
Here are some of the reasons:
- I use "floating frames" (also called "inline frames") to display my problems and solutions (so that
I can use special characters).
Older versions of Netscape didn't support this feature, so I started
developing everything using Internet Explorer.
- Then, somewhere into my many projects, I learned that Internet Explorer is much more "forgiving" than
Netscape (Mozilla, Firefox,
I discovered, after-the-fact, that some of my coding doesn't work in Netscape browsers.
- So, I should now be sure to test all my new coding in Netscape browsers, right?
- BUT, now, all my new coding uses MathML.
I had figured out how to get MathML to work
in Internet Explorer, by having people download MathPlayer.
What about Netscape products?
- Well, I then discovered that there is a Universal Math Style Sheet that solves a lot of the problems
regarding the display of MathML in a wide variety of different browsers and platforms!!! GREAT!!!
And I've tested it, and it works!!!
- BUT, I will need to write all my code in XHTML, not HTML.
In particular, Mozilla/Firefox natively supports MathML, but only in XHTML documents.
And XHTML is much stricter than HTML.
- Plus, I need to learn XHTML.
I need to learn XHTML anyways, because my online HTML course is now out-of-date
and I want to turn it into an XHTML course.
- So, the next big project that I start from scratch (probably my Precalculus web site,
after I finish the Algebra I, Geometry, and Algebra II sites) will, I promise,
be coded in XHTML, will use the Universal Math Style Sheet, and will be accessible to LOTS more people!
- Also, it's just me doing all of this. (It's what I LOVE to do!)
I have lots of formal mathematics education,
but I am self-taught (yeh for the O'Reilly series!)
- So, again, my apologies.
It really does sadden me that my site is not more easily available to more people.
- By the way, I recently learned about SVG (Scalable Vector Graphics) which, like MathML, is an
Just as MathML is the future of math on the web, SVG is the future of graphics on
I should be able to code all the mathematics-type graphics I need!
Of course, I've got to learn SVG too (book on the way)
and, SVG needs to be embedded in XHTML documents
