This is beyond the bounds of the rich-text field in Airtable. You might be able to get close to what you want through Markdown, but I’ll bet you’ll be very disappointed if rendering precision matters greatly.
The only way to do this well - i.e., blend data with content in a database environment is to ensure that HTML and CSS are working for your benefit. It is certainly possible to build HTML content in the long text field of Airtable, but testing how it will render is very difficult.
There’s nothing inherently wrong with pairing the data management aspects of Airtable with an external HTML page design tool but that would require some clever integrations.
