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.

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

If the attribute is missing or its value is invalid, its value is inherited from its parent element: so the element is editable (or not) based on the parent element.
