How to create a Full-Page Background with CSS ?

Last Updated : 09 Feb, 2024

To create a full-page background with CSS, set the body's height to `100vh` to cover the viewport, and add a background image using `background-image`. Ensure the image fills the entire viewport without distortion by setting 'background-size: cover'. Optionally, adjust 'background-position' and 'background-repeat' for alignment and repetition preferences.

Syntax

body {
  height: 100vh;
  width: 100vw;
  background-image: url('your-image.jpg');
  background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
}

Approach

Set height: 100vh; for the body to cover the viewport height.
Use background-image to add the desired image.
Adjust background-size: cover; to ensure the image covers the entire viewport without distortion.
Optionally, set background-position: center; and background-repeat: no-repeat; for better alignment and to prevent repetition.
