Final answer:
Titles of full-length works and containers, like books, websites, and music albums, are italicized, while titles of shorter works within larger ones, such as short stories and articles, should be placed in quotation marks.
Step-by-step explanation:
When punctuating the titles of containers or full-length works like a website, a book, a music album, or a television show, they should generally be italicized. For example, the title of a book, an entire website, or a music album would be presented in italics. On the other hand, shorter works or those that are part of a larger work or container, such as articles in periodicals, pages on a website, short stories, songs, or episodes of TV programs, should be enclosed in quotation marks.
When the author of a work is unknown, the same formatting applies: put the title of the article in quotation marks, while the title of a book or a journal is in italics. The title of the website is also italicized, and the first word of the title, any subtitle, and proper nouns are capitalized.
