CSS Background Attachment Property

The CSS background-attachment property allows web developers to control how background images behave within their elements. This property can enhance the aesthetics of a website and improve user experience by providing a more interactive feel. Understanding how to use this property is essential for anyone looking to delve into the world of web design. In this article, we will explore the background-attachment property in detail, including its syntax, values, and practical examples.

The background-attachment Property

The background-attachment property in CSS is used to specify whether a background image scrolls with the page, stays fixed in one position, or scrolls with the element’s content. This behavior significantly affects how the image appears when users scroll through the website.

Definition and syntax

The syntax for the background-attachment property is straightforward. Here is the basic structure:

        
background-attachment: value;
        
    

Where value can be one of three possible options that we will explore next.

Values of the background-attachment property

The background-attachment property accepts three values:

• scroll: The default value. The background image moves with the content when the user scrolls.
• fixed: The background image remains fixed in one position, even when the content is scrolled.
• local: The background image scrolls along with the element’s content, allowing for a different visual effect.

1. scroll

The scroll value allows the background image to move along with the page content. It is the default behavior.

2. fixed

The fixed value keeps the background image locked in position, which can create a striking visual effect as users scroll.

3. local

The local value means the background image scrolls with the content of the element itself, not the overall page.

Examples

Let’s look at some practical examples of the three values of background-attachment.

            background-attachment: scroll;
            background-size: cover;
            background-position: center;
        }
        
    

Example of fixed

            background-attachment: fixed;
            background-size: cover;
            background-position: center;
        }
        
    

Example of local

        
        .local-example {
            height: 400px;
            overflow: auto;
            background-image: url('https://example.com/image.jpg');
            background-attachment: local;
