Issues using Make4ht
Colors (MWE)
You can use custom colors in LaTeX using color o xcolor packages. Both packages provide a common set of commands for color manipulation, but xcolor is more flexible and supports a larger number of color models, so is the recommended approach. [Using colors in LaTeX]
Normally, to change the color of a text you can use \color or \textcolor commands. The problem is that tex4ht doesn't support \color command, so you need to use \textcolor.
Ex.: Instead of using \color{red} some text, you should use \textcolor{red}{some text}.

Multiple line math equations (MWE)
When using multiline math equations like
- bmatrix
- cases
- array
You need to insert a line break before the last line of the equation using \\ (two backslashes), otherwise this last line will not be rendered in the HTML output from make4ht.

Sometimes fbox can generate an math error (MWE)
Use \boxed instead of \fbox
Phantom doesn't work in make4ht (MWE)
Using \phantom directly with make4ht give us an "math input error", to avoid this you should use some package like ifpdf.
Ex.: Instead of using \phantom{=} use \ifpdf \phantom{=} \else \fbox{\phantom{=}} \fi.

Tex4ht MathML code has an error when you use tools like that with MathML. [Awnser by michal.h21].
You can include this configuration in the make4ht configuration file to fix it.

- Subfigures (deprecated: https://ctan.org/pkg/subfigure?lang=en)
- Math line breaks (still not supported by Mathjax https://tex.stackexchange.com/questions/702447/make4ht-compiled-html-math-doesnt-justify-with-text)
- algorithm bad formatting (algorithm2e package)
- texorpdfstring duplicating text = needs hyperref package!
- hyperlinks not hyperlinking
