Image moves from its position

Hello! I’m doing this project and i’m trying to give the tape effect in the photo on “end-section”. I’m having two problems: one, when i resize the webpage that “tape” img moves and, two, when i open the website in full screen the image just disappears. Do you guys can help me understand what i’m doing? Thank you!
