CSS list-style-image property
The list-style-image property in CSS is used to specify a custom image to use as the marker for list items in an unordered list (<ul>). This property allows you to replace the default list markers (like bullets or numbers) with a custom image, enhancing the visual appearance of lists.
Syntax

list-style-image: url(image_url);
}
selector: The element to which you want to apply the list style (e.g.,ul).image_url: The URL of the image to be used as the list item marker.
Values
url(image_url):- Description: Specifies the URL of the image to be used as the marker. The URL can be relative or absolute.
- Example:
url('path/to/image.png').
none:- Description: Removes any custom image marker and uses the default marker style (usually a disc or bullet).
- Example:
list-style-image: none;.
Examples
Basic Usage
