A method of displaying and navigating information using a hierarchical, spring loaded DHTML menu system that adjusts to fit the boundaries of a resizable, container (FIG. 1). A set of standard HTML table row elements, having a hierachical dependency (11), is consistently displayed as a web-page, under reasonable resizing. This is done using a strut row that produces the largest width requirement when the table structure is resizing to occupy a small width. Only the current row elements and the strut element are required in calculating table resizing to ensure that whichever data elements are displayed when a web-page resizing occurs, the browser auto-layout algorithm calculations will result in a resize attributes that enables all other row elements of that menu to be accommodated by the newly determined table width. As the row elements may themselves be table structures, nested menus of information may be displayed and navigated (12).

A server-based browser system provides a server-based browser and a client system browser. The client browser reports the position of a user click on its display screen, hotspot ID, or URL to the server-side browser which retrieves a Document Object Model (DOM) model and view tree for the client and finds the location on the Web page that the user clicked on using the coordinates or hotspot ID received from the client. If there is a script associated with the location, it is executed and the resulting page location is requested from the appropriate server. If there is a URL associated with the location, it is requested from the appropriate server. The response Web page HTML definition is parsed and a DOM tree model is created which is used to create a view tree model. The server-side browser retrieves a style sheet, layout algorithms, and device constraints for the client device and lays out the view model using them onto a virtual page and determines the visual content. Textual and positional information are highly compressed and formatted into a stream and sent to the client browser which decodes the stream and displays the page to the user using the textual and positional information.
