Adobe Portfolio - customizing global styles
I'm new to Adobe Portfolio, using the Sawdust theme, and am trying to apply global text styles to pages I've already created, but it does not seem to be applying those styles across the whole site - styles only changes if I highlight each block of text and change it manually.
I've tried to update globally a number of ways...
-I highlight a block of text and choose "Paragraph" in the dropdown, but the styling does not change to the global Paragraph style I've already set.
-I go to Media Content Styles > Paragraph and change the global styling there, changes are not applied site wide.
-Under Site Wide > Colors & Font, the only options I see are a single color palette and font dropdown menu with the font I chose as my Paragraph font, but that font has not been applied anywhere except where I've changed it manually.
Is this just a glitch in the Portfolio platform?
Is there any way to view the HTML or custom CSS outside of the WYSIWYG editor to ensure the styles are being applied correctly?
I would also like to add new text styling (eg H1 / H2 / H3, bulleted lists, etc etc) - is there any way to do this vs simply editing the few existing default styles?
