This article shows you how to apply or update the guidebook fonts and colours for individual guides. If you want to apply the same colours and fonts to all of your guides at once, go here to learn how to do that.
Go to the Guides tab and click on the name of the guide where you want to change the fonts or colours. On the Guide Details page click Edit on the Guide Branding section. To change the fonts or colours for this guide only, click No on the Use account level fonts & colours. This opens up a box so you can choose unique fonts or colours for this guide here.
This can be done in the same way for all the guides you may want to have unique font or colours for.
When making changes it may be worth having your guide preview open in another browser tab so that you can refresh the page and see your changes after you’ve saved them.
