You can usually find all of the pieces of information you need to create a citation--like the title, author, and date--on the first page of an article, usually in one of the upper corners or along the bottom of the page. The journal title will usually appear in italics. The words "Volume" and "Issue" may be written out in full, abbreviated, or not present at all, and sometimes instead of the word "Issue" you may see the word "Number" or abbreviation "No."
You will also likely need to look at the database record for the article to find information such as the database name and the DOI or permanent URL.
