Our Support team is capable of handling simple requests such as changing font color, font size, images, header images, padding, or similar one-line updates and adjustments. Learn how to contact HubSpot Support here.
For more substantial updates, HubSpot offers access to certified HubSpot agencies that specialize in designing on the HubSpot COS as well as more generalized website design services. HubSpot also offers a free COS Designer Certification course to help you gain confidence in making these design edits yourself.
If you are an experienced website developer needing assistance, your best resource for questions is our COS Design forum on the Community.
