Pick a website that is simple, preferably with no different-sized columns.
See below for example websites, if you can't find one you want to recreate.
Avoid using the dev tool inspector.
Don't worry about functionality.
Focus on colors, images, fonts, spacing and text.
google.com
allbirds.com
Feel free to cut corners if you must, for example to simulagte a nav bar or a complex layout, you can take a screenshot of the actual site and use that as a placeholder.
