HTMLElement: contentEditable property

The contentEditable property of the HTMLElement interface specifies whether or not the element is editable.

This enumerated attribute can have the following values:

• 'true' indicates that the element is contenteditable.
• 'false' indicates that the element cannot be edited.
• 'plaintext-only' indicates that the element's raw text is editable, but rich text formatting is disabled.
• 'inherit' indicates that the element inherits its parent's editable status.

You can use the HTMLElement.isContentEditable property to test the computed boolean value of this property.
