Show and Hide element when click

Hello, I’m doing a site where I need to have your title, your song and the song lyrics when you click on one of the angels. It turns out that I need to click on it again to disappear with your content before clicking on another angel, otherwise it will appear above the previous content. I need that when I click on an angel and then when I want to click on another one it automatically disappears the previous content. Can someone help me?
