Welcome to a tutorial on how to create a responsive fullscreen background image in HTML CSS. Need to add a background image that will look nice on both big and small screens?
Creating a responsive fullscreen background image is as easy as setting a background image to cover the entire window – body { width: 100vw; min-height: 100vh; background: url("IMAGE") center no-repeat; background-size: cover; }.
That covers the quick basics, but read on for the example!

PART 2) THE CSS
background.css
/* (A) FILL ENTIRE WINDOW */
body, main {
width: 100vw;
min-height: 100vh;
}
/* (B) - BACKGROUND */
body {
/* (B1) REMOVE DEFAULT PAGE SPACING */
margin: 0; padding: 0;
/* (B2) BACKGROUND IMAGE */
background: url("city.webp") center no-repeat;
background-size: cover;
}
/* (C) - FOREGROUND */
main {
padding: 20px;
color: #fff;
background: rgba(0,0,0,0.5);
} Just what is happening here?
- We set both
