A two-step process to determine the layout of an electronic document such as a webpage or an article is provided. The electronic document is selected from a summary page that displays summaries of several documents. In the first pass, an image of the selected document is identified in the summary page and the end of the image is marked as a target location for doing a partial layout. A partial layout that includes a location for the image is then determined and stored. The image is animated to the determined location. In the second pass, while the image is being animated, a full layout is determined for the document. The full layout uses the stored results of the first pass and generated the layout from the target location to the end of the document.
