Hi Aaron,

first you need to create portfolio items under Admin -> Portfolio

second for each portfolio item you need to assign a hero image

and third you need to create a page with Showcase Template and assign it as front page.

Hello Aaron,

For each page you can set the background color of the page (this will affect the foreground color)

and in customizer -> general settings you have 'Enable Fullscreen menu on desktop'
