CSS list-style-image Property

CSS list-style-image property

In this tutorial, you will see how the CSS list-style-image property works, its usage, syntax, values, examples, how to use it, and more. So, let’s begin.

Usage

We use CSS list-style-image property to define images as list-item markers. By default, HTML uses bullets and numbers as list-item markers. This property overrides the default condition.

Syntax

list-style-image: url | none | initial | inherit | revert | revert-layer;

Property Values

The list-style-image has the following pre-defined values.

  • URL – It is the path where the image is located. The image will be used as a list marker.
  • none – It’s the default value, no image will be used as a list marker.
  • Global Values: initial | inherit | revert | revert-layer | unset.
/* URL Example*/
list-style-image: url('image.jpg');
/* You can also specify gradient like this below*/
list-style-image: linear-gradient(to top right, yellow, orange);
/* None is the default value */
list-style-image: none;
/* Global values example */
list-style-image: inherit;
list-style-image: initial;
list-style-image: unset;
list-style-image: revert;
list-style-image: revert-layer;

How to use list-style-image

We have two different methods to apply list-style-image property to the HTML list items.

First Method: Inline-CSS

<ul style="list-style-image: url('uploads/autumn-leaves.png');"> 
    <li>United States</li> 
    <li>Canada</li> 
    <li>Japan</li> 
    <li>United Kingdom</li>
    <li>Germany</li>
    <li>Singapore</li> 
</ul>

As you can see in the above code, we can use the style attribute to apply the list-style-image property to the list.

Code Output:

Second Method: External CSS stylesheet

For this, you just need to put the CSS rule in your external stylesheet. For example, if it’s an ordered list then simply use the element selector such as ‘ol’.

The following CSS code will change the bullets of an ordered list to the image defined.

ol {
    list-style-image: url('autumn-leaves.png');
}

Tip: You can create a unique class to apply images to specify items.

Using Icons

You can also use icons instead of images to make your lists look more elegant.

list-style-image icons example

To do this, first, you need to download icons. It can be in any format, but I always prefer SVG. After that, put the CSS code to apply them to the list markers. The syntax is the same as you have seen above.

Code Example to use SVG icons:

<ul style="list-style-image: url('flag-icon.svg');"> 
    <li>United States</li> 
    <li>Canada</li> 
    <li>Japan</li> 
    <li>United Kingdom</li>
    <li>Germany</li>
    <li>Singapore</li> 
</ul>

Using Gradients

Gradients can also be used instead of images or icons.

Code Example:

<ul style="list-style-image: linear-gradient(to top right, yellow, red);"> 
    <li>United States</li> 
    <li>Canada</li> 
    <li>Japan</li> 
    <li>United Kingdom</li>
    <li>Germany</li>
    <li>Singapore</li> 
</ul>

Common Issues

1. list-style-image size

What if the image size is bigger than the list of items?

The problem is common as you can see in the image below.

list-image-style size example

To solve this problem, you need to resize the image before using it. The image that I used was 200px wide, I changed this to 28px wide. That’s the reason the images are perfectly sized.

For resizing images, you can use any photo editor tool like photoshop, or canvas.

Furthermore, there is no other way to resize list-style images using CSS. However, you can use a background image instead of this property.

That’s all. This is how the list-style-image property works.
