CSS The type of output connector used determines how the CSS is used with the HTML output: • With the SMTP (MIME) connector, the CSS is integrated in the HTML. • With other connectors, a CSS file is generated that the output HTML links to. This default behavior can be overridden by the Inline CSS setting for the HTML unpaginated driver. For more information about the SMTP (MIME) connector, se the Input and output connectors > Creating emails documentation.
