We are not going to touch that node, we even donвЂ™t draw it on diagrams, but itвЂ™s there.

But thereвЂ™s a rule вЂ“ if somethingвЂ™s in HTML, then it also must be in the DOM tree.Д®verything in HTML, even comments, becomes a part of the DOM.Д®ven the directive at the very beginning of HTML is also a DOM node. We may think вЂ“ why is a comment added to the DOM? It doesnвЂ™t affect the visual representation in any way. We can see here a new tree node type вЂ“ comment node, labeled as #comment, between two text nodes. In other cases everythingвЂ™s straightforward вЂ“ if there are spaces (just like any character) in the document, then they become text nodes in the DOM, and if we remove them, then there wonвЂ™t be any. If we put something after, then that is automatically moved inside the body, at the end, as the HTML spec requires that all content must be inside.Spaces and newlines before are ignored for historical reasons.So, for instance, in the example above the tag contains some spaces before, and that text becomes a #text node (it contains a newline and some spaces only). They form text nodes and become a part of the DOM. Spaces and newlines are totally valid characters, like letters and digits. a newline: в†µ (in JavaScript known as ).

Please note the special characters in text nodes: It may not have children and is always a leaf of the tree.ДЇor instance, the tag has the text 'About elk'. The text inside elements forms text nodes, labelled as #text. Tags are element nodes (or just elements) and form the tree structure: is at the root, then and are its children, etc.

On the picture above, you can click on element nodes and their children will open/collapse.
