Document: designMode property
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.
Value
A string indicating whether designMode is (or should be) set to on or off.
Valid values are on and off.
Examples
Make an <iframe>'s document editable:
iframeNode.contentDocument.designMode = "on";
