HTML hidden attribute

The global attribute hidden is a boolean attribute that indicates an element is not yet or no longer relevant. For example, it can be used to hide a page element until the login is completed. If an element has this attribute set, it will not be displayed.

Changing the CSS display property of an element with the hidden attribute will override this behavior. For example, if the element is set to display: flex, it will be displayed even though the hidden attribute is set
