Reply to: Custom CSS not being read for webhelp outputFebruary 12, 2016 at 8:45 pm
I've tried exactly what you describe and it works for me.
The “Specific CSS” setting puts that filename into a in the HTML pages', similar to this:
Check to see that that is being done.
You also seem to have copycss set correctly (ANT_PARAM_args.copycss = yes), and that tells the DITA OT to actually move the CSS from the location you specify to the root folder of the output.
If those two things are happening (the file is at the correct place and being loaded) and your CSS settings are not being reflected in the HTML then your problem is probably a CSS cascading issue. Some other CSS selector may be taking priority.
