The Short Answer
Hitting the 'Back' button in a browser reloads the previous html file. That worked great for a long time because websites were structured as a series of files. But since JavaScript was developed, many sites will load one file and then dynamically change the content being shown to user *without loading a new file*. Hitting back no longer works as you would expect because the previous content isn't from the previous file. The way it used to work is like a book. If you wanted new content, you would just turn the page. If you wanted to see the previous content, you'd turn the page back. But now it's like a book made out of video screens. The content on each page can change now. If you want to go back to what you just watched, turning to the previous page won't work. You need to rely on the current page's own navigation system.
