In order to create a single page web we needed to create anchor pages by using:

> Build > Pages

> Build > Navigation menu

Pages do not allow you to create only an anchor page like "#about", it creates an url + anchor, concatenated

Navigation menu do not allow you to create an link page with only an anchor
