Param shortcode

[!note] To override Hugo's embedded param shortcode, copy the source code to a file with the same name in the layouts/_shortcodes directory.

The param shortcode renders a parameter from front matter, falling back to a site parameter of the same name. The shortcode throws an error if the parameter does not exist.

We found a {{%/* param "color" */%}} shirt.

Hugo renders this to:

<p>We found a red shirt.</p>

Access nested values by chaining the identifiers:

{{%/* param my.nested.param */%}}
