Squarespace has many wonderful templates but many of them are variations of a "theme" - or "framework". This can be good to know when you are looking for a template with specific functions, i.e., 2 sidebars, parallax scrolling, one pagers, etc.
Thanks to Greg Sargent of www.sqsp.guru for doing his insight on all things Squarespace.
