A web editing application provides a user interface for editing a web page on a client computing device. A characteristic associated with the client computing device is determined. A web page comprising visual elements can be rendered. Layout data describing locations and sizes for individual visual elements of the visual elements can be determined. Cells can be generated based at least in part on the layout data and the characteristic associated with the client computing device. Each of the cells can have a location corresponding to a location of a respective visual element of the visual elements and individual of the cells can be interactable to enable editing of the web page. Based on an interaction with the at least one cell of the cells, an edit to the web page can be determined and the web page can be updated based on the edit to the web page.
