There are two options for editing fonts in your project. You can edit with style override, where the edits only apply to the specific text selected, or edit your theme, where the edits would apply to the text component edited, and thus in all places where this component is used on your project.
Editing fonts with style override
Editing fonts with style override creates changes that only apply to the specific text you selected.
To edit fonts with style override, select the text you want to edit, then go to 'Text' on the right-hand side of the screen.
Here, you can accordingly edit the font style for your chosen text.
Editing fonts in your theme
Editing fonts in your theme creates changes that would apply to the text component edited, and thus in all places where this component is used on your project.
To edit fonts in your theme, go to your chosen theme, where you will have the option to edit ‘Typography.' You can then choose which text component you would like to work with. You can choose among several font families, font styles, sizes, heights, spacing, and colors.
While designing, you will simultaneously be given a preview of the text design, applying each of your chosen design settings.
