No matter what era, the screen at that time could not accommodate as many elements as possible, such as a large number of files in folders or various media on Web pages. This website contains one of the indispensable elements in interaction design - scroll bar, presentation and interaction in different systems. There are both familiar operating systems and operating systems that most people have never heard of. I don't know which operating system you like, but I prefer the crystal clear feeling of Mac OS X 10.0 2001.
