There are several properties you can look at in order to determine the width and height of elements, and it can be tricky to determine which is the right one for your needs. This article is designed to help you make that decision.  Note that all these properties are read-only.  If you want to set the width and height of an element, use  width and height; or, the overriding min-width and max-width, and min-height and max-height properties.
document.designMode controls whether the entire document is editable. Valid values are "on" and "off". According to the specification, this property is meant to default to "off". Firefox follows this standard. The earlier versions of Chrome and IE default to "inherit". Starting in Chrome 43, the default is "off" and "inherit" is no longer supported. In IE6-10, the value is capitalized. 
Gets/sets the domain portion of the origin of the current document, as used by the same origin policy.
Returns the height of the document object. In most cases, this is equal to the <body> element of the current document.
The URL read-only property of the Document interface returns the document location as a string.
The HTMLElement.style property returns a CSSStyleDeclaration object that represents only the element's inline style attribute, ignoring any applied style rules.  See the CSS Properties Reference for a list of the CSS properties accessible via style.
The HTMLFormElement.length read-only property returns the number of controls in the <form> element.
Accepts two optional parameters: Image([unsigned long width, unsigned long height])
The HTMLInputElement.multiple property indicates if an input can have more than one value. Firefox currently only supports multiple for <input type="file">.
The HTMLTableElement.rows read-only property returns a live HTMLCollection of all the rows in the table. The rows included in the associated <thead>, <tfoot> and <tbody> elements.
