On a page with video playback, sometimes we need to scroll the page to view video-related content information, such as profiles, related comments, etc., then when scrolling the page, the video player will leave the window area, this time we can use JS and CSS technology will The player toggle is fixed to the bottom right corner of the page.
Use jquery to detect the scrolling event of the window and switch the videoBox's class class to the appropriate position to hide and appear in the lower right corner.
