Understanding the CSS background Property

While tools like ScanCSS help you manage your code, understanding the core CSS properties — like background — helps you build visually rich websites.

The background property in CSS is used to define the background styling of HTML elements. It can set a color, image, position, repeat behavior, size, and even more, all in a single line.

Basic Syntax

css

selector {

  background: value;

}

You can also use specific sub-properties:

·         background-color

·         background-image

·         background-repeat

·         background-position

·         background-size

·         background-attachment

Example

css

body {

  background: #f9f9f9 url("background.jpg") no-repeat center center/cover;

}

This single line sets:

·         A light gray background color (#f9f9f9)

·         A background image (background.jpg)

·         No repeat

·         Centered positioning

·         Covering the entire element
