Q. How do I create an MLA citation for articles I found online?

The formatting rules for a page on a website are:

Author's Last Name, Author's First Name. "Title of Page or Article." Title of Website, Website URL. Accessed DD MM YYYY.

Example (from Purdue OWL's MLA Formatting/Style Guide):

Lundman, Susan. “How to Make Vegetarian Chili.” eHow, www.ehow.com/how_10727_make-vegetarian-chili.html. Accessed 6 July 2015.

You can use citation generators to automatically create citations for websites.  Some are listed in the COM Library Cite MLA Style guide on the left of the page under Citation Generators.
