Container Shortcode
Some shortcodes enclose content: [my_wrapper]…content…[/my_wrapper]. The Container
Shortcode element is for exactly those — you give it the shortcode, and whatever
elements you nest inside it are rendered as the content between the opening and closing
tags.
How it works

The Content tab has one control, Full Shortcode — enter the shortcode with its
attributes, e.g. [my_wrapper style="boxed"]. You only write the opening tag; Oxygen
handles the closing tag itself.
Then build the content: the element is a container, so add any elements inside it. At
render time Oxygen runs the shortcode with your child elements as its enclosed content
— equivalent to [my_wrapper style="boxed"]<your elements>[/my_wrapper].
If what you entered isn't a valid shortcode, the element renders an "Invalid shortcode"
message instead.
On the front end
The element renders a wrapper div with a generated per-element class and the
oxy-container-shortcode class, containing the shortcode's output — which in turn
contains your child elements wherever the shortcode places its content. Note: some
shortcodes ignore enclosed content entirely; with those, your children won't appear —
that's the shortcode's behavior, not a styling issue.
