Usually we need modals and pop-ups on the website for different things. This code uses a pop-up. This pop-up is provided to remove something from the website. Suppose you have a table and you want to delete a row from it. It is best to be warned beforehand to make sure the deletion operation is complete. In this code, this warning is done with the help of a pop-up. This pop-up is full width and its background color is white.
