Plug-in Requirements description

The jquery plugin is mainly resolved as the scroll bar scrolls to fix a div, and the mouse rolls with the float fixed at the top. When we scroll through the Web browsing, we want to anchor an ad or select article in the sidebar so that when the user rolls down, the sidebar is not blank, increasing exposure and click-through, increasing revenue and traffic.
Of course, sometimes when designing a Web page, the sidebar will also use the side to be fixed floating in there, while scrolling. In this case we can use this plugin as well.
