Yes, I think so, as they all use the same browser engine. > > Yes, I noticed this duplication also when I was looking at the .css, > Actually some had more duplication than others, and I did not know why. > > For example this is duplicated 4 times > But this one earlier in the .css file, is duplicated 6 times ! > They are duplicated for every vertical line. What is wrong is that they are same. They all use a different ID, to address each particular vertical line in tables. > This is why the .css is so large.

This is the downside of the fact that you have such large files. Maybe I could make a make4ht filter that tries to make the CSS file smaller, but it won't be easy. > > Thank you for the fix.
