Referencing CSS stylesheets with link[rel=stylesheet] or @import causes browsers to delay page rendering while a stylesheet loads. When loading stylesheets that are not critical to the initial rendering of a page, this blocking behavior is undesirable. The new standard enables loading stylesheets asynchronously, without blocking rendering, and loadCSS provides a JavaScript polyfill for that feature to allow it to work across browsers, as well as providing its own JavaScript method for loading stylesheets.
