HubSpot Designer Docs
Welcome to HubSpot's Designer Documentation site. The HubSpot Content Optimization System (COS) is a powerful and flexible platform to design beautiful websites, blogs, and emails. Our core designer documentation has been revamped, based on feedback from the COS designer community.
HubSpot's Designer Docs are organized into the following sections:
- COS Reference
Reference docs related to general COS design features and concepts
- HubL Reference
Comprehensive reference guides to HubSpot Markup Language
- COS Tools
Development tools for designers
Walkthroughs and code snippets
The site is now actively being built out; therefore, we will continue to improve these docs and release more content. To get started, use the sidebar navigation or submit a query below.
