<p>The <strong><code>Text</code></strong> interface represents the textual content of {{domxref("Element")}} or {{domxref("Attr")}}.  If an element has no markup within its content, it has a single child implementing <code>Text</code> that contains the element's text.  However, if the element contains markup, it is parsed into information items and <code>Text</code> nodes that form its children.</p>
<p>New documents have a single <code>Text</code> node for each block of text. Over time, more <code>Text</code> nodes may be created as the document's content changes.  The {{domxref("Node.normalize()")}} method merges adjacent <code>Text</code> objects back into a single node for each block of text.</p>
