How to Use the Guided Custom CSS

If you are a premium user, there will be a new options panel named Custom CSS in your Advanced Tab.

When you open it, you should see something like this:

Our Guided Custom CSS

Any CSS styles you enter here will only be applied to the current block you are editing. You won’t have to worry about your styles affecting unwanted places.

You might be wondering why we call this feature “guided”, this simply means that we’ve already laid out for you a list of CSS classes you’ll need in order to modify the block through CSS. You won’t have to dive into the block’s source to find out the CSS class names.

Just fill out the necessary areas with your own style rules.

Fill it up with your style rules.

After adding your custom CSS, the block should show your changes right away.

You don’t also have to worry about the empty CSS selectors, Stackable removes the unused ones so that we can keep your pages loading fast.

How to Transfer Billing to your Client

If you have created a website for your client and you have purchased Stackable Premium on their behalf, you can transfer the ownership and billing of Stackable Premium to your client.

You can easily transfer billing to your client by doing these steps:

1. Login your Stackable account through this link:

2. Navigate to Renewals and Billings, then select your plan and click on “Cancel Auto-Renew“.


3. Navigate to Websites and click on your client’s website in the list. Then click on “Transfer Billing to Client“.


4. Afterwards, a popup will open which will notify your client of the transfer. Input your client’s name and email. An email with a direct purchase link will be sent to your client so they can associate their billing with Stackable Premium while keeping the license and management on your end. You will get a notification when this will happen.

Will My Staging Site Count as a Site in My License?

Nope, your staging site, local development site, or tests site won’t be counted as a site in your license.

If you are under a single site license, it should be fine to use your license key in another another site for staging/testing/development purposes as long as the domain matches these:

Here are the Top-level domains that are considered as dev or staging:

  • *.dev
  • * (DesktopServer)
  • *.test
  • *.local
  • *.staging
  • *.example
  • *.invalid
  • * (GoDaddy)
  • * (Cloudways)
  • * (WPSandbox)
  • * (tunneling)

And here are the Subdomains that are considered as dev or staging:

  • local.*
