Fullscreen Pro – Using home page style for categories

Hello. I finally found a theme I like (Fullscreen Pro) that I wanted to use for a my work website. I have two work so all my articles are separates in two categories. But even with the Pro version I don't arrive to keep the home screen style of "Fullscreen" theme in others pages likes categories. So my articles are note in fullscreen. The home page is perfect, I just want to filter the articles displays in two categories. Do you know how it can be possible ? And I don't know any code. Thanks a lot.
