I recommend OWL Purdue website for information about how to properly format in MLA style 

https://owl.purdue.edu/owl/research_and_citation/mla_style/mla_formattin...

For example: 

WITH AUTHOR 

In-text --> (Last Name) 

Last name, First name. "Name of Article." Name of Website, Date Published, link to article. 

WITHOUT AUTHOR

In-text --> ("Shortened Name of Article")

"Name of Article." Name of Website, Date published, link to article.
