Hey dear judge friends, finally I've finished this challenge. I've gathered so many things through completing it. Anyway, I had to face a bad situation which is the blue background images. Actually, inside the starter file, there was no background image, and I've converted a div to a background image, in fact, it's not an image. It looks perfect in the viewport of the desktop, but in responsive design what I mean is in mobile or tablet viewport responsive design, it was so problematic that's why I've ignored these background divs without desktop design. Here I have two request for you -

1. Please judge my code and give me feedback.
2. If you have a bit of time, please redesign the viewport responsive background div for tab, mobile.
