CARD
Type: Background trigger
Scope: self (Text Area background)
Purpose: Exports Text Area (and teasers) as floating card
By default, the Text Area is exported as a borderless rectangle. If you add the CARD export option to the $blogBkgOpt, the Text Area acquires all the attributes you set for the PostBody Widget in the Styles Dash—color, opacity, two border settings, and four shadow settings.
This option make a big impact on notes that export with teasers—i.e., the Home page and various category pages. By default, teasers export as subsections delineated by horizontal rules. Add the CARD export option, and the teasers become floating cards instead.
The color of a levitating card is determined by the color you assigned in the Styles Dash to the PostBody Widget. You can override this by setting $blogCardColor.
