+                The Document Object Model (DOM) is a cross-platform and
+                language-independent interface that treats an HTML or XML document
+                as a tree structure wherein each node is an object representing a
+                part of the document. The DOM represents a document with a logical
+                tree. Each branch of the tree ends in a node, and each node
+                contains objects. DOM methods allow programmatic access to the
+                tree; with them one can change the structure, style or content of
+                a document. Nodes can have event handlers (also known as event
+                listeners) attached to them. Once an event is triggered, the event
+                handlers get executed.
+              </p>
+              <p>
+                The principal standardization of the DOM was handled by the World
+                Wide Web Consortium (W3C), which last developed a recommendation
+                in 2004. WHATWG took over the development of the standard,
+                publishing it as a living document. The W3C now publishes stable
+                snapshots of the WHATWG standard.
+              </p>
+              <p>In HTML DOM (Document Object Model), every element is a node:</p>
+              <ul>
+                <li>A document is a document node.</li>
+                <li>All HTML elements are element nodes.</li>
+                <li>All HTML attributes are attribute nodes.</li>
+                <li>Text inserted into HTML elements are text nodes.</li>
