CSS Lists

HTML Lists and CSS List Properties
In HTML, there are two main 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

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
• Add background colors to lists and list items

Different List Item Markers
The list-style-type property specifies the type of list item marker.

The following example shows some of the available list item markers:

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;
}

Note: Some of the values are for unordered lists, and some for ordered lists.

An Image as The List Item Marker
The list-style-image property specifies an image as the list item marker:

Example

ul {
    list-style-image: url(‘sqpurple.gif’);
}

Position The List Item Markers
The list-style-position property specifies whether the list-item markers should appear inside or outside the content flow:

Example

ul {
    list-style-position: inside;
}

Remove Default Settings
The list-style-type:none property can also be used to remove the markers/bullets. Note that the list also has default margin and padding. To remove this, add margin:0 and padding:0 to <ul> or <ol>:

Example

ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
}

List – Shorthand property
The list-style property is a shorthand property. It is used to set all the list properties in one declaration:

Example

ul {
    list-style: square inside url(“sqpurple.gif”);
}

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.

Styling List With Colors
We can also style lists with colors, to make them look a little more interesting.

Anything added to the <ol> or <ul> tag, affects the entire list, while properties added to the <li> tag will affect the individual list items:

Example

ol {
    background: #ff9999;
    padding: 20px;
}
ul {
    background: #3399ff;
    padding: 20px;
}
ol li {
    background: #ffe5e5;
    padding: 5px;
    margin-left: 35px;
}
ul li {
    background: #cce5ff;
    margin: 5px;
}
