Reference: email layout
This is a reference guide of special Knock variables, and generated CSS styles that are used in email layouts.
Special Knock variables
There are a few special variables used in email layouts to populate and assemble the final email notification template.
| Variable | Description |
|---|---|
content | A notification template defined in an email channel step will be inserted into this variable. This is a required variable, and must be present somewhere in every layout. |
footer_links | A list of footer links, as configured in the layout editor, will be injected into this variable. |
Generated CSS styles
When you use the visual template editor to build your email notification template, we auto-generate and include the following CSS styles in the email layout. They provide base styles for certain components, which you can override or extend them as needed.
