The disabled attribute is a boolean attribute.
When present, it specifies that the button should be disabled.
A disabled button is unusable and un-clickable.
The disabled attribute can be set to keep a user from clicking on the button until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript could remove the disabled value, and make the button usable.

In XHTML, attribute minimization is forbidden, and the disabled attribute must be defined as <button disabled="disabled">.
