SNAPPING CONTENT HEADER IN SCROLLED DOCUMENT

A system includes a processor that executes instructions stored in a memory to create a rendering engine that renders a document in a scroll container in a user interface (UI) on a computing device. The document contains one or more content header components associated with respective document contents and is scrollable through the scroll container. At least one content header component is scrolled out of view in the scroll container when a first portion of the document is scrolled out of the scroll container bringing a second portion of the rendered document in view in the scroll container after scrolling. In response, the rendering engine snaps the one content header component that has been scrolled out of view back into the scroll container so that the one content header component is in view along with second portion of the rendered document that is in view in the UI after scrolling.
