Short remarks: TtM codes the calligraphic fonts of the LaTeX source by italic characters (the Laplace operator ℒ, the Fourier transform ℱ and the test function space 𝒟 in my example). With moderate manual effort I changed this by substituting those with appropriate calligraphic xml characters in the TtM output. The displayed calligraphic variant depends on the browser of the viewing device, but should be consistent for inline expressions as well as for those in the displaymath environment. This is the case with TtM. Analogously I changed the bold characters for the set of the real and the complex numbers to the more common ones ℝ and ℂ.
In the LaTeX file I added prior to TtM manually environments for “theorem” etc., since TtM ignores .cls style files. I omitted the author’s addresses, which were added in the original article. Below you see the test HTML page generated by TtM from the slightly modified LaTeX file with some pre- and post-processing, which now is inserted into a responsive WordPress Website (adjust height to your file):

<object width=100% height=6000 data=”./documents/my_file.html” type=text/html></object>.

The anchors for the references below in the example work well with Google’s Chrome/Chromium, when the example is inserted as a HTML object in a WordPress page, but not with Firefox. When the pages are opened in a tab external of WordPress these anchors work also with Firefox. Unfortunately with such a view outside of WordPress with a smartphone all expressions in displaymath are shown very small. Open for example with smartphone in new tab ltivp-ttm.html to check it.
