<!DOCTYPE html> <html> <head> <style> body { background-image: url('/css/images/css.jpg'); background-repeat: no-repeat; background-attachment: fixed; } </style> </head> <body> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed.
