assets = find(tree);

Reference

$3

Finds all assets referenced by the CSS AST in tree. The AST must be in the
format that css-parse generates.

Returns an array of objects that each have a url property that specifies the
URL referenced, a node property that contains a reference to the AST node
that references the asset, and a position property that specifies the
location in value that the reference was found.

The position object contains index and length properties that specify the
starting index and the length, respectively, of the url(...)` call that
references the URL.
