The LibreOffice download site is full of pain/animation, which can trigger migraines and nausea. Migraine warning for the link: https://www.libreoffice.org/ If you click on the link, it fires an animated carousel. If you get that out of the way, and mouse over the seartch area, that fires more animation.
If you don't like the animation on the home page (and I understand why, I'm not so fond of carousels myself), you could always just bookmark the download page directly https://www.libreoffice.org/download/download/.
A safer alternative is good, but a site which hurts users is still bad.
The website is being redesigned at the moment. Probably Ilmari can give you more information
Yeah, I don't want to have animations on the new site. I am building it with accessibility & hypersensitivity concerns in mind.
