In HTML, there are two types of List: Unordered Lists and Ordered Lists.
- Unordered Lists - Use bullets to mark items on the list.
- Ordered Lists - Use numbers (Regular numbers, or Roman numbers), or letters to mark items on a list.
CSS List properties allow you to set the following:
- Allow choose the type of ::marker that will be seen in the Unordered List.
- Allow choose the type of ::marker that will be seen in the Ordered List.
- Use an image as an ::marker for an Unordered List.
- Sets the location of ::marker.
The CSS list-style-type property is used for the <UL> (Unordered List) tag to set the style for the items of the list.
The CSS list-style-type can take one of the values:
- disc

The CSS list-style-image property is used for the <UL> tag to display an alternative image for ::markers.
Notes: the list-style-image takes precedence over the list-style-type. If the image provided by list-style-image does not exist or cannot display list-style-type to be used.
<ul style="list-style-image: URL('../right-arrow-16.png')">
<li>HTML</li>
<li>CSS</li>
<li>Javascript</li>
</ul>
The CSS list-style-position property is used for the <UL> and the <OL> tag to set the position of the ::markers.
Possible values of the CSS list-style-position are:

The image below shows the HTML List structure, and you can use CSS to change its margin/padding.
Here is an example of the customized margin/padding of the HTML List:
margin-padding-example.css
ul {
background: #3399ff;
padding: 20px;
}
ul li {
background: #cce5ff;
margin: 5px;
}
ol {
background: #ff9999;
padding: 20px;
}
ol li {
background: #ffe5e5;
padding: 5px;
margin-left: 35px;
}
