Hi Nasser,
you can use
\Configure{qquad}{\HCode{\string\#x00A0;}}
to configure \qquad in your config file. It don't have a configuration
by default. \, can be configured with \Configure{,}, but it seems that
this work only in math mode, if I understand correctly definition in
tex4ht-4ht.tex:
Hi Michal,
\Configure{qquad}{\HCode{\string\#x00A0;}}
Wouldn't it be better for \qquad to actually insert 2em, as in
span style=width:2emnbsp;/span
(css out of my head, probably wrong, but you get the idea.)
Likewise \quad - 1em.
Also, it's not clear to me why it should be unbreakable.
