How to create a child theme in HubSpot

A child theme is basically a copy of the original HubSpot theme which you can edit, change or customize the core files without altering the original theme. This way, you can still get the important theme updates from the asset provider, while you're enjoying the custom modifications in your own files, templates, modules etc. as well as the theme settings.

When you create a child theme, you'll have a new folder in your Design Manager which includes the following files:

  • child.css
  • child.js
  • theme.json

Additionally, if the original (parent) theme has a template that is linked from other core files, you'll have that template file too. For example, when you create a child theme for the most popular theme for HubSpot, Focus, you'll have these files in your child theme folder:

  • Cloning a theme and creating a child theme are different things. If you want your theme keep updated by the asset provider, you should create a child theme.
  • Creating a child theme in HubSpot is optional. If you're not planning to change a core file or add your own, you don't have to create a child theme.
  • If you copy a template from the original theme into a child theme and if the asset provider updates the template in the future, please keep in mind that your template in the child theme won't be updated.
