About

import-css contains 2 variants of importCSS function

link.js variant uses <link> tag. If you want to import multiple styles for "progressive loading" recommended move all function calls before </body>.
link-in-body.js also uses<link> tag, but this variant a little lighter than link.js because of restricted to use only in <body>.

Also exist *-async.js variants of both files, where you can import CSS outside of queue.
