Hello Neil,

You are welcome.

1.  That problem I posted about has to do with an equation I pulled out of an
article on Differentiable Manifolds.  The column alignment specification IS in the source
code.  The problem is Firefox does not left justify the two equations to the left bracket
UNTIL the cursor is moved into the table cell of the equation.  They are first center
aligned then they "pop" into the correct position when the cursor is moved over them.

I am ignorant as to how to left justify in this situation without using CSS. 
I would welcome learning how to do this in a better way

2.  I did not know that the arrows should have stretched on their own.
Should not the arrows look the same even if a person manually sets the size
rather than letting the size be automatically set?

I noticed a couple of things that you did that were workarounds to get it to display in Firefox that might cause problems in other renderers:

  1. You use CSS to set the column alignments instead of using MathML.  You list the Firefox bug that it doesn't implement columnalignments, but you should at least also add the columnalignments to the MathML so that other renderers will align properly.
  2. You  set minsize/maxsize for the arrows in Cicho's Diagram. These should stretch on their own to be the proper size, but Firefox doesn't do this (I don't see it listed as a bug in your list).
It's really good to get complex tests like this.  Thanks for the work.

Hello MathML Community,

While learning TeX and MathML, I wrote a one page website
that covers a range of mathematical formulas, I use the web-page
for testing some of a browser's MathML (presentation Markup)
capabilities.  It might be of use to others, so here it is:

https://eyeasme.com/Joe/MathML/MathML_browser_test.html

The equations are shown in 3 forms:
(all hyperlinked to the code that generated them)

1) an image the TeX presentation
2) an image of the MathML representation using STIX Beta fonts on Firefox 3.5
3) the present browser's representation of the equation using MathML

This way a person can see how TeX (produces a very good representation of
mathematical equations) compares with MathML on Firefox 3.5 using STIX beta
fonts, and how these both compare with their present browser's MathML
representation.

The page validates as 'XHTML 1.1 plus MathML 2.0', validates as 'CSS level 2.1'
and the page passes the WAI automatic tests

Included on the web-page are a few useful links and some notes about lessons
I learned while making the web-page.

Feel free to make any Comments / suggestions / corrections.
