Bootstrap 5 Overview Disabled forms

In Bootstrap, you can easily disable input in a form and stop it from interacting by using the disabled attribute. This is mainly used in forms where some fields are not available for all users to fill in. Although buttons are visibly disabled with this attribute you need to add the tabindex="-1" to completely discourage it from being focused by the keyboard. If we add the disabled attribute inside a <fieldset> tag will disable the whole page from taking inputs and interacting.   

Syntax:

<input class="..." id="..." disabled>

Used Attributes:
