Hi Bill, > > https://www.albany.edu/dept/math-stat/hammond/demos/tex4ht/hilmar.html
Thanks for this demo. You are right that there are some issues with spaces. I've took a look at their support in tex4ht and found that there is no support for \:, \! or \; in tex4ht sources. So I've added them. The widths of corresponding <mspace> elements is based on fractions on this page: https://chenfuture.wordpress.com/2008/03/22/math-spacing-and-length-units/. The \quad should really be 1em, but \ should be much smaller than it is right now, I've set it to 0.33 em. Best regards, Michal
