To document this officially, I am posting this here also. screen shot at above
link.

=====================
\documentclass{article}
\usepackage{amsmath}
\begin{document}    

   \[
    W = \begin{vmatrix}
\sqrt {x} & {x}^{{\frac{3}{2}}} \\ 
{\frac {1}{2}{\frac {1}{\sqrt {x}}}} & {\frac {3}{2}\sqrt {x}}
\end{vmatrix}
\]          
\end{document}
==============

Compiled using

       make4ht foo3.tex "mathjax"
tex4ht produces ":" in raw HTML before mathjax process it. Here is raw HTML
