Hi Jennifer,
If want to modify styles for text which is maintained in Word documents you may either
modify the target template assigned to your target (usually c1h_html.dot for html based targets) and leave it to DocToHelp to generate a css out of this
or
you modify c1h_html.css directly. c1h_html.css is in the target folder, subfolder LinksExt. You must take caution that D2H does not overwrite your modification with the next build.
The C1H_HTML_full.css is only be used for HTML sources.
BTW, Dan Beall has written a very informative article about these styles stuff, please see
