So what exactly a modal is ???

modal window is a graphical control element subordinate to an application’s main window. It opens a small layer/window on top of the parent screen with a slight backdrop so that you can see the parent too. The advantage of this box is that you don’t need to navigate between pages, instead, change data in it close it and you are back on parent screen.

Modals/pop-ups can be created easily with few lines of code. There are various ways to create a modal and almost all methods are probably similar. We will discuss one of the methods here. To see another method, scroll below.
