Just in general you can style WebYep text elements with CSS in Freeway. I’m not sure about v3, but in previous versions you had to put a space on either side of your WebYep object then select all to apply a class style rather than applying to div the object is in.
Don’t forget that I did a whole series on building an entire WebYep-based website as a real project for a real client, not 3.0, but the only new major update really in 3.0 was the SEO action. The function of the actions hasn’t changed and how they are integrated into Freeway.
You can also add external style sheets to your site so that the client can have access to the styles you used in FW (the manual has a tutorial on how to do this), plus one of Dan’s webcast show’s how to do this as well.
