CSS Lists
The CSS list properties allow you to:
- Set different list item markers for ordered lists
- Set different list item markers for unordered lists
- Set an image as the list item marker
List
In HTML, there are two types of lists:
- unordered lists (<ul>) - the list items are marked with bullets
- ordered lists (<ol>) - the list items are marked with numbers or letters
With CSS, lists can be styled further, and images can be used as the list item marker.
Different List Item Markers
The type of list item marker is specified with the
list-style-type property:
Example
ul.a {
list-style-type: circle;
}
ul.b {
list-style-type: square;
}
ol.c {
list-style-type: upper-roman;
}
ol.d {
list-style-type: lower-alpha;
}

Some of the values are for unordered lists, and some for ordered lists.
An Image as The List Item Marker
To specify an image as the list item marker, use the list-style-image property:
The example above does not display equally in all browsers. IE and Opera will display the image-marker a little bit higher than Firefox, Chrome, and Safari.
If you want the image-marker to be placed equally in all browsers, a crossbrowser solution is explained below.
Crossbrowser Solution
The following example displays the image-marker equally in all browsers:
Example
ul
{
list-style-type: none;
padding: 0px;
margin: 0px;
}
ul li
{
background-image: url(sqpurple.gif);
background-repeat: no-repeat;
background-position: 0px center;
padding-left: 15px;
}

Example explained:
- For <ul>:
- Set the list-style-type to none to remove the list item marker
- Set both padding and margin to 0px (for cross-browser compatibility)
- For all <li> in <ul>:
- Set the URL of the image, and show it only once (no-repeat)
- Position the image where you want
it (left 0px and
vertical value: center)
- Position the text in the list with padding-left
List - Shorthand property
The list-style property is a shorthand property. It is used to set all the
list properties in one declaration:
When using the shorthand property, the order of the property values are:
- list-style-type (if a list-style-image is specified,
the value of this property will be displayed if the image for some reason
cannot be displayed)
- list-style-position (specifies whether the list-item markers should appear inside or outside the content flow)
- list-style-image (specifies an image as the list item
marker)
If one of the property values above are missing, the default value for the
missing property will be inserted, if any.
