Theme: Emporia, problem: remove lines on home page

I use a theme called Emporia: http://demo.graphpaperpress.com/emporia/
In the theme demo, the home page is without the lines you se if you for example click on “portfolio”, and it has this nice slideshow. I can not figure out how to do this..! And, I can’t find out how I get the three pictures that links to the different galleries under “portfolio”. Anyone?? I would be so greatful..
