This code first displays an alert dialog that is played by clicking on any price from the music page. Then the screen turns colored and the background color changes to a gradient. Text is also displayed automatically. The color of this text is pink with gradient. This text appears at the bottom of the page and then disappears and another text is displayed. Clicking anywhere on the music screen will be displayed automatically.
