+ * Represents an HTML <div> element.
+ *
+ * The [DivElement] is a generic container for content and does not have any
+ * special significance. It is functionally similar to [SpanElement].
+ *
+ * The [DivElement] is a block-level element, as opposed to [SpanElement],
+ * which is an inline-level element.
+ *
+ * Example usage:
+ *
+ *     DivElement div = new DivElement();
+ *     div.text = 'Here's my new DivElem
+ *     document.body.elements.add(elem);
+ *
