H1 and H2 Fonts on New Blog

Does anyone know how to change the H1 and H2 font sizes in the new blog? They seem like they are not propositioned correctly. This should be an easy fix…

As Heath says above, you are much better suited going to the Wix Blog’s own community to ask about this if it just about the apps own settings.

Plus, remember that the app has it’s own Wix Support pages that you can read.

However, if you are wanting to customise it yourself, then go down the Corvid route as shown here.
