Here’s the thing most people don’t realize: a website’s design, original layout, and code are protected by copyright the moment they’re created. You don’t have to register anything or put a little © symbol on it. It’s automatically protected. So when you copy those elements without permission, you’re infringing on someone’s copyright — full stop.
According to the Stanford Copyright and Fair Use Center, copyright infringement happens whenever copyrighted material is copied from or posted to a website without authorization from the owner. That includes code, images, original layout structure, written content — basically anything creative that someone built.
And the U.S. Copyright Office is clear that you can’t claim ownership of someone else’s work no matter how much you tweak it — unless you have the owner’s consent. So the “I changed a few things” defense doesn’t really hold up.
Not making money from your site doesn’t protect you either. Copyright law doesn’t have a “small hobbyist” exception. There are limited defenses like fair use — but those apply to very specific situations (like commentary, parody, or education) and are much harder to rely on than most people think. Plenty of companies actively hunt for infringers — some even use automated programs called spiders that crawl the web looking for stolen content and design elements. If they find you, you could get a takedown notice demanding you remove everything, or in worse cases, face an actual lawsuit.
It’s totally fine to look at other sites for inspiration — that’s just how design works. But there’s a real difference between “I love how they laid this out, let me think about something similar” and copy-pasting their CSS or lifting their images wholesale. One is learning. The other is theft.
