I made a one-page website with the generatepress theme. I’m not completely happy with the highlighting of the menu item corresponding to the section on the page. The highlighting is not steady, you see it go on and off when you scroll slowly.
Basically it are 2 pages because i added a blogpage.
The problem with the on/off highlighting started after adding the blog page. Then i had to use the whole url/#id for the menu items in stead of #id only.
@ Mark and Suzanne, the header is made with the pageheader addon. Just enter a text with some html for size and color. And select the add parallax effect option.
