2.	About Page. "about.html"
2.1.	Create an About page that has sections that contains a "description":
2.1.1.	Two important dates. The "date" sections in the About page MUST link to that month.html file. (SEE #5) 
2.1.1.1.	EXAMPLE: If your site is about famous big cats, one of your important dates could be Aslan’s birthday. The section will highlight Aslan with an <h2>Aslan’s Birthday</h2>; an image of Aslan; and a paragraph (lorem ipsum or copy from Wikipedia page) and a link to the december.html file. The december.html file will have 12/25/2020 highlighted as the famous lion’s birthday. (NOTE: I do not know if this is Aslan’s birthday, but it is a good guess.)
2.1.2.	A short description (lorem ipsum) of the business’ founder[s].
2.1.2.1.	 This section will only need a heading <h2>, a paragraph and a link that brings the user to the employee page’s founder[s] section.
