.
.attributes is a collection of all attribute nodes registered to the specified node. It is a NamedNodeMap,not an Array, so it has no Array methods and the Attr nodes' indexes may differ among browsers. To be more specific, attribute is a key value pair of strings that represents any information regarding that node; it cannot hold Object. Attribute can hold additional data/information that is required while processing custom JavaScript. There are many predefined attributes for different nodes used for binding events, validations, and specifying layout informations that are handled by browser (may vary from browser to browser).

Though the specification requires localName to be defined on the Node interface, Gecko-based browsers implement it on the Element interface.

offsetParent returns a reference to the object which is the closest (nearest in the containment hierarchy) positioned containing element. If the element is non-positioned, the nearest table cell or root element (html in standards compliant mode; body in quirks rendering mode) is the offsetParent. offsetParent returns null when the element has style.display set to "none".
