Inserts content before one or more HTML elements, which can be:
l The elements that match the selector of a script (see "results" on page1427).
l One element that matches the selector of a script that runs for "Each matched element"
(see "this" on page1345 and "Setting the scope of a script" on page874).
l The elements returned by a query in the template (see "query()" on page1299).
See also: "after()" on page1351.

Before(content) inserts content before one or more HTML elements and creates a new result
set.
content
String, HTML string or result set to insert after the elements. In case a plain text string is
provided, it is automatically wrapped in a <span> element to avoid orphan text nodes to
appear in the <body> element.
