When using off-the-shelf "\frac" to display a continued fraction,
such as in:
a_0+\frac{1}{a_1+\frac{1}{\ldots+\frac{1}{a_k}}}

things get unreadably small pretty quickly. I'd like to be able to
display them with all coefficients the same size as the leading
coefficient. An example of what I'm seeking is: <https://sites.millersville.edu/bikenaga/number-theory/finite-continued-fractions/finite-continued-fractions.html>

(This certainly looks as if it was generated by TeX/LaTeX.) Does
anybody here have an example of how to achieve this effect?

more like prunes than rhubarb does.

The image alt text on the page you referenced contains LaTeX code, for example:

$$\dfrac{4}{\pi} = 1 + \dfrac{1^2}{2 + \dfrac{3^2}{2 + \dfrac{5^2}{2 + \cdots}}}.$$

\dfrac is provided by amsmath.

That works great. Thanks!

Just out of curiousity, is it common to put TeX in as the alt attribute?
Being lazy, I would have just put the whole pdf up. Screenshotting each equation or derivation and inserting them into an HTML replication of
the original text is something that I never would have thought of.

It's more likely that the HTML content was automatically created from
TeX or LaTeX source. I think putting the source code in the alt text is
fairly common with LaTeX to HTML generators. It's not particularly
readable but it at least provides some information for users relying on
screen readers or Braille displays.

LaTeX docs and formulas can be turned into HTML with special tools
that keep the math looking good. MathJax and MathML are key for dis-
playing complex math right in browsers.

Pandoc is a pretty versatile tool for turning whole LaTeX documents
into HTML, and it can do stuff like --mathjax to drop in LaTeX math
delimiters (for inline and display) that render dynamically. TeX4-
ht and lwarp compile LaTeX while making HTML, usually pairing with
MathJax for formulas since they might output LaTeX source or images
otherwise. Other routes include dedicated converters like Recovery-
Tools TEX or Hyperlatex for batch work, though they differ in how
they handle advanced packages.

MathJax is a JavaScript library that renders LaTeX math directly in
HTML by loading embedded code like E = mc^2 into browser-friendly for-
mats such as SVG or HTML/CSS. It supports AMS-LaTeX extensions, con-
figurable renderers (like via right-click menus), and works in tools
like Quarto or RMarkdown without full document conversion. Include it
with a CDN script tag for client-side rendering, keeping formulas as
editable source while appearing typeset.

MathML is a W3C standard for native math in HTML5, convertible
from LaTeX via Pandoc's --mathml flag, producing semantic markup
like <math><mi>x</mi></math> for accessibility and screen readers.
Browsers like Firefox support it natively, while others use Math-
Jax as a polyfill to convert LaTeX to MathML on the fly. This combo
shines for EPUBs or standards-compliant sites but you need conver-
sion tools for full LaTeX input.
