HubSpot’s CMS is a powerful, flexible platform for creating HubSpot websites, including website pages, blogs, and lightweight apps. It features built-in security and reliability features, along with a globally distributed Content Delivery Network (CDN) that ensures fast page load times. When developing on the HubSpot CMS, you can use your preferred tools, technologies, and workflows, such as GitHub, while developing websites. Content creators can then create pages and publish content using drag and drop editors. And because the CMS is integrated with the CRM, you can create dynamic website experiences for your visitors based on the data you already have.

​
Before you begin

Before you start, ensure you’ve done the following:
  • Create a free test account to build without impacting a production environment. You can use either of the following types of accounts:
  • Install Node.js, which enables HubSpot’s local development tools. Versions 18 or higher are supported.
1

Install the HubSpot CLI

Once you’re ready to begin, open a terminal window and create or navigate to the directory where you want your local HubSpot files to live. This working directory is where the theme and its associated files will be placed.Next, run npm install -g @hubspot/cli@latest to install the HubSpot CLI, which introduces an hs command that allows you to easily interact with your HubSpot account.
2

Configure the local development tools

Run hs account auth to connect the tools to your HubSpot account. This command will walk you through the following steps:
  1. First you’ll be guided to create a personal access key to enable authenticated access to your account via the local development tools. You’ll be prompted to press “Enter” when you’re ready to open the Personal Access Key page in your default browser. This page will allow you to view or generate your personal access key, if necessary. (Note: You’ll need to select at least the “Design Manager” permission in order to complete this tutorial.) Copy your access key and paste it in the terminal.
  2. Next, you’ll enter a name for the account. This name is only seen and used by you, For example, you might use “sandbox” if you’re using a developer sandbox or “company.com” if you’re using a full customer account. This name will be used when running commands.
Once you’ve completed the config file setup flow, you’ll see a success message confirming that a configuration file, ~/.hscli/config.yml, has been created in your home directory.

Create a theme

Run hs create website-theme my-website-theme to create a my-website-theme directory populated with files from the CMS theme boilerplate.
4

Upload your theme to HubSpot

Run hs upload my-website-theme my-website-theme to upload your new theme to a my-website-theme folder in your HubSpot account.Once this task has completed, you can view these files in the design manager of your HubSpot account. The design manager is an in-app code editor that displays the developer file system, and can be found by navigating to Content > Design Manger in the left sidebar of your account.
5

Create a website page

To experience how content creators will use your templates and modules, create a website page using the theme you just uploaded.
  • In your HubSpot account, navigate to Content > Website Pages
  • In the upper right, click Create, then select Website page.
  • In the dialog box, enter a name for your page, then click Create page.
  • On the next page, select the my-website-theme theme if it’s not already selected. Then, hover over the Homepage template and click Select template.
  • You’ll then be brought to the website page editor where you can explore all of the options that content creators will have when working with the template. Learn more about using the editor to build and customize pages on HubSpot’s Knowledge Base.
  • Click the Settings tab in the editor, then select General. Enter a Page title, then set a Content slug to finalize the page’s URL. Then, close out the dialog box by clicking X or pressing the Escape key.
  • In the upper right, click Publish to take your page live.
6

Edit a CSS file

Run hs watch my-website-theme my-website-theme. While watch is running, every time you save a file, it’ll be automatically uploaded. Open your theme’s /css/components/_footer.css file in your editor, make a change (such as updating the .footer__copyright selector to have color: red;), and save your changes. Your terminal will show that the saved file has been uploaded.Reload your published page to see the CSS change reflected on your website.

​
What’s next?

You’re encouraged to continue to explore and experiment with the boilerplate theme and the page-building experience. The sandbox account you created is yours to play around in and experiment with. You can checkout HubSpot’s Inspire gallery to see websites, landing pages, and web apps built on HubSpot. You might also want to check out the following documentation:
