Growthkit Premium Theme Documentation 2025

A child theme inherits the assets and files from the parent theme, it only includes a few files to create the dependency and allows for customization while still retaining updates.

In HubSpot, it is not possible to edit files for themes purchased from the asset marketplace. While it is possible to build your website using the original parent theme, using a child theme is a future-proof way of building your website in CMS Hub.

Creating a child theme requires access to Design Tools (formerly Design Manager), don't worry, no code skills are required! Just follow these steps to create a child theme in your HubSpot account.
