Variable Templating in Arguments
Some attributes (see below) accept a template as an argument; a string which may contain references to Strapi fields. Strapi fields are referenced by giving the field name wrapped in double curly braces {{}}.
For example,
background: {{background_color}}; would be transformed into background: red;.
An attribute using the above template would look like this,
strapi-css-rule="background: {{background_color}};".
This attribute would create an inline CSS rule for the element, with a substitution of the value held in the Strapi field background_color in place of {{background_color}}.
Attributes that accept variable template arguments:
strapi-into, strapi-css-rule, strapi-single-type-into, strapi-single-type-css-rule
