Position elements relative to a moving mouse pointer. Move elements based on a timer. Innovative Web authors can easily expand beyond this list of simple examples and create impressive and clever Web pages by exploiting the capabilities of dynamic properties. This article covers the following topics. Benefits of Dynamic Properties Implementing Dynamic Properties Notes on Implicit Dependencies Related Topics Benefits of Dynamic Properties Dynamic properties simplify and minimize the amount of code required in a document.
Authors can use dynamic properties to implement functionality formerly possible only with scripting.
This frees authors from the requirement of learning script programming before they can design advanced features for their pages. Dynamic properties are similar to a spreadsheet's implementation of a formula. In a spreadsheet, a cell's value can be a constant or a formula. A formula can include references to any number of other cells in the spreadsheet. Likewise, a dynamic property can reference other properties on the same document.
