Bootstrap 4 Modal

Bootstrap 4 Modal

The Modal is a component of Bootstrap 4, which is a dialog box or pop-up window. The modals are used to provide information or warning to the user, such as give information about the session time out or ask for confirmation about critical actions before proceeding to the next step.

The bootstrap 4 modal appears at the top of the web page. The modal is created by using the Bootstrap modal plugin.

Basic Modal – The basic modal consists of a header, message body, and footer with some action buttons. The header is used to describe the title of the dialog box, the message body is used for the description, and the footer consists of the action button (such as a close button) which is used to perform the task.
