Modal dialogs create overlays on open modal windows that provide options for a user to control the closing behavior of a dialog while interacting with it.
Users can launch multiple dialogs simultaneously or one above the other based on their z-index (z-depth) to make additional dialogs (nested modal dialogs).
A variety of smooth, built-in animations are available to configure for the opening and closing of modal dialogs. They perform based on CSS3 animation from the Animation library.
The modal dialog can resize from any of the edges or borders of the dialog within the target container by using its handle (grip) or hovering on it.
The modal dialog can be closed by clicking on a close icon, with an overlay click, or by pressing the ESC key. Users can also restrict the closing behavior of a dialog based on its callback function parameters.
