A method includes creating a base layer for a page in the presentation document, wherein the base layer comprises a plurality of placeholder elements wherein each placeholder element has an absolute position and size. The method further includes creating an interactive layer for the page in the presentation document, wherein the interactive layer comprises a plurality of interactive element overlays representing a plurality of interactive elements and each interactive element overlay has an absolute position and size that corresponds to the absolute position and size of a placeholder element in the base layer. The method further includes sending the base layer and interactive layer of the page to each client computing device for rendering, wherein each interactive element overlay is rendered on top of its corresponding placeholder element.
