 <p>The <strong>Document Object Model (<em>DOM</em>)</strong> is a programming interface for HTML, XML and SVG documents. It provides a structured representation of the document (a tree) and it defines a way that the structure can be accessed from programs so that they can change the document structure, style and content. The DOM provides a representation of the document as a structured group of nodes and objects that have properties and methods. Nodes can also have event handlers attached to them, and once that event is triggered the event handlers get executed. Essentially, it connects web pages to scripts or programming languages.</p>

Dit is echter niet  zo eenvoudig. Om historische en technische redenen gaan formulierelementen (widgets) en CSS niet zo goed samen. Daarom maaken veel ontwikkelaars hun eigen HTML widgets om de vormgeving van formulieren in eigen hand te houden. Dankzij de moderne browsers hebben webontwikkelaars meer en meer controle over het ontwerp van formulierelementen.</p>
