With the Fabulous theme you can choose between using an infinite scrolling function that loads more posts as you scroll down the page (like other popular sites such as Pinterest) or you can choose to use standard style pagination (numbered). This way if you prefer one of the other you can easily choose your favorite via the Customizer.
