MLA 8/9 is designed around the idea of containers. For example, a book is its own container; an article is contained in a journal, magazine or newspaper and the journal, magazine, or newspaper may be contained in a database.
The example below shows how to use the template to cite a newspaper article found in a library database (ProQuest). Sections 1-2 are core elements. Sections 3-9 are the first and second containers. You fill in the template with the information available. That information will differ and vary depending on the type of source you are citing.
To guide you through the process, MLA has created a practice template.
