Works from the web can typically be changed or removed at any time, so while it's optional, the date which you accessed material is often important. This is especially true when there is no date specifying when an item was produced. This date will be added to the end of the entry, e.g. Accessed 11 April 2018.
The format of dates is: Day Month (shortened) Year. E.g. 11 Sept. 2017.
Whether to give the year alone or include a month and day depends on your source: write the full date as you find it there.
If no date is listed, omit it unless you can find that information available in a reliable source.
Capitalize the first letter of every important word in the title. You do not need to capitalize words such as: in, of, or an.
If there is a colon (:) in the title, include what comes after the colon (also known as the subtitle).
