This element ends with a period.
The location element refers to page number or page numbers in a print resource or the web address (URL) or a digital object identifier (DOI) for online resources.
"For online works, the location, in order of preference, is the DOI, permalink, or URL" (MLA Handbook, 9th ed., p. 188).
"If your source offers a URL that it identifies as stable, permanent, or persistent (sometimes called a permalink), use it in your entry instead of the URL that appears in your browser, and copy it directly from the source" (MLA Handbook, 9th ed., p.195).
For a single page, use p., for a range of pages use pp.
