Hi Nasser, I think you need to provide correct configuration for \small and \text commands for MathJax, it clearly doesn't like it. And it doesn't like double brackets as well. I am sure examples of command configurations are somewhere in the TeX4ht mailing list archives. I may try to come with something tomorrow.

https://tex.stackexchange.com/questions/543136/problem-using-tex4ht-in-mathjax-mode-when-using-array-with-text

When compiling this MWE

==============
\documentclass[11pt]{article}
\usepackage{amsmath}
\begin{document}

\[%
\begin{array}
[c]{c}%
\text{{\small bottom edge}}\\
\text{{\small bottom edge}}\\
\end{array}%
\begin{bmatrix}
\alpha & 2\\
1 & \alpha \\
\end{bmatrix}%
\]
\end{document}

=======================

Using the command

make4ht -ulm default foo.tex "htm,mathjax"

it produces bad output (please see screen shot in the above link).

When compiling the same file using lualatex foo.tex the output in pdf is correct.

How to make tex4ht output the same as in the pdf?

The raw HTML generated by tex4ht is
