1) When you want to disable the div, set its disabled attribute as usual (just to comply with the convention) 2) In your div’s click and/or key handlers, check if disabled attribute is set on the div. If it is, then just disregard the click or key event (e.g. just return immediately).
The :disabled pseudo-class selector provides conditional styling to HTML elements that can receive user input, when the elements have the disabled attribute. It is defined in the CSS Selectors Level 3 spec as a “UI element state pseudo-class”, meaning it is used to style content based on the user’s interaction with an input element.
