Add News and Portfolio Items to Old Website

I have an old website. I need 10 news items added to the website and 7 portfolio items added to the website. There is a "News" page that has a list of news items with links to a page with the full news story. There is a "Portfolio" page that has a list of items with links to a page with the portfolio details. There are already news items and portfolio items on the website. I only need these new ones added. The menu needs to be adjusted to point to these new items. This should be done using HTML, CSS and JavaScript only. Do not use any server-side languages. I will provide the items in Word Document format.
