Well-made websites for free?

Firstly, I would like to say that I condemn pirating software, movies etc.

I’m a software developer that focuses much more on back end that front end, therefore I am trying to find a well-made template.

Issue is, all well-made costs, most of the times a hefty amount.

Since my project is for personal use only, wanting to test out some features, I am looking for free, well-made websites (framework or not, doesn’t matter).

Any ideas where I could find such?
