This is a FrameMaker 12 > Publish question: Where do I style the numbers of an ordered list for Responsive HMTL5 and Microsoft HTML Help?

This is a multi-step process.

First, if you do NOT have a character tag being applied to the autonumber of the list, you need to create a new template that does this.

You can either specify the desired font attributes here in the FM template and let the Publish module automap them or you can explicity map the Character tag styling in the Publish settings [more control].

You then use the Set Template option in the Style Mapping to assign this modified template to be used when FM converts the document to MIF for processing by the Publish routines.
