I have a style I'm currently using for headings. Since you cannot delete "Heading 1" from the list of styles, I'd like to copy the settings for my existing style to "Heading 1." Is there an easy way to do it? Since Heading 1 doesn't exist in my .css file, I can't just copy and past the text.
You haven't said which version of RoboHelp you are using. Please always start a thread with this information as it can affect the answer.
In this case the version may not matter. Open your CSS in source view or a text editor.
Add the three lines below and paste your definition into the line between the brackets.
It's very unusual for a RoboHelp created CSS not to have H1 defined so check carefully.
