    How Display Content In Modal Popup window using Lightning Web Components (LWC):

    If we need to show something in modal dialog we need to use predefined slds class "slds-modal" . LWC modal has three section i.e header, body(modal content), footer. If we use "slds-modal__header" class we can show sticky header in modal window and by using "slds-modal__footer" class we can show sticky footer where usually show save, cancel buttons. By using "slds-modal__content" class we can show modal body content.

    In below example code we are showing lightning button, on click of that button, modal popup window will be opened.
