How do I customise fonts in a theme?

To edit the fonts in a theme:

1. Either click on "Create New Theme" or select an existing theme.

2. From the side menu, click on "Fonts."

3. Edit the fonts, and you will see the changes in real time in the preview section. Set font family, font size(S,M,L), font weight and or make them uppercase.

4. Save the changes.
