This is neat!

One small thing I noticed is that in the Binomial theorem, “k=0” is hidden by sigma, unless I zoom in a little. If I zoom back out afterwards, it’s fine until I start scrolling again.

I don’t know anywhere near enough css to guess what’s going on.

That part's actually not the .css stylesheet, but MathJax's conversion result. I run a website with over 150 formulae, at which point client-side MathJax becomes impossible (unless you're okay with a page taking 2 minutes to fully load due to formula-by-formula conversion) so I actually use _real_ LaTeX (XeLaTeX, technically) to convert maths to .svg files and include those instead.
