Jacquard-generated content is passed over to Movable Ink as a single piece of text. But if there are line breaks in your Jacquard-generated content, you can style each line differently with a few simple steps.
In Movable Ink, double-click on the default text layer and click Edit Property.
Change the Text Variant Index Line dropdown to Line 1.
Duplicate the text layer and change the Text Variant Index Line to Line 2.
Now, you can adjust the individual lines. Click on Preview at the top of your screen to see your changes.
Repeat this process for any additional multiline language Jacquard has generated.
