navigational elements like menus or app bars are often fixed to the top. If you plan to actually navigate to different pages on the website, you've removed your ability to do that. It's also possible that the creator of the site did some weird stuff and the entire body has fixed positioning for some weird reason. You can't predict how people will use innocuous CSS rules, and randomly deleting elements just because they have a certain style is easy but wildly imprecise. Seems better to just set everything with position: fixed to be position: static and unset any overflow rules.
