Comprehensive Guide to CSS Backgrounds
CSS Backgrounds Summary
CSS backgrounds play a vital role in enhancing the visual appeal of web pages. This guide explores the essential concepts for effectively setting backgrounds in CSS.
Key Concepts
1. Background Properties
CSS offers various properties to customize backgrounds:
- background-color: Sets the background color of an element.
- background-image: Applies an image as the background.
- background-repeat: Controls how the background image repeats (e.g.,
repeat
,no-repeat
,repeat-x
,repeat-y
). - background-position: Specifies the starting position of the background image (e.g.,
top
,bottom
,left
,right
,center
). - background-size: Defines the size of the background image (e.g.,
cover
,contain
, or specific dimensions).
2. Shorthand Property
You can combine all background properties into one using the shorthand background
property:
background: [background-color] [background-image] [background-repeat] [background-position] [background-size];
3. Multiple Backgrounds
CSS allows you to stack multiple backgrounds on a single element, separating each background with a comma:
background: url('image1.png'), url('image2.png');
4. Background Attachment
The background-attachment
property determines whether the background image scrolls with the page or remains fixed:
- scroll: Default; the background moves with the content.
- fixed: The background stays in place while scrolling.
- local: The background scrolls with the element’s content.
Examples

body {
background-color: lightblue;
}

background-image: url('background.jpg');
background-repeat: no-repeat;
background-position: center;
}
Example 3: Multiple Backgrounds
header {
background: url('header-bg.jpg'), url('overlay.png');
}
