CSS list


The CSS list properties work as follows:

  • Set up different list items to mark as ordered lists
  • Set different list items to mark as no sequence tables
  • Set the list item to be marked as an image

List

In HTML, there are two types of HTML lists:

  • No Sequence Table - Marker of list items uses special graphics (e.g. small black dots, small boxes, etc.)
  • Ordered list - The tags for list items use numbers or letters

With CSS, you can list further styles and mark them with images as list items.


Different list item tags

list-style-type specifies that the type of list item tag is:

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;}

Try it out . . .

Some values are unseeded tables, and some are ordered lists.

The following is a description of the common property values of the list-style-type property:

  • none Bullets are not used
  • disc Solid circle
  • circle Hollow circle
  • square Solid block
  • decimal Arabic numerals
  • lower-alpha lowercase English letters
  • upper-alpha Capital Letters
  • lower-roman lower-case Roman numerals
  • upper-roman Capital Roman numerals

The image marked as a list item

To specify an image marked by a list item, use the list style image properties:

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

Try it out . . .

The above examples vary across major browsers, with IE and Opera showing image tags a little higher than Firefox, Chrome and Safari.


Tips:
  • list-style-position determine whether a flag appears outside or inside the content of a list item.
  • If you want to place the same image logo in all browsers, you should use a browser compatibility solution in the following ways.

Browser compatibility solutions

Also in all browsers, the following example shows the image tag:

ul {
list-style-type: none;
padding: 0px;
margin: 0px;
}
ul li {
background-image: url(sqpurple.gif);
background-repeat: no-repeat;
background-position: 0px 5px;
padding-left: 14px;
}

Try it out . . .

Examples explain:

  • Ul:
    • Set the list style type to have no list item tags
    • Set padding and margin 0px (browser compatibility)
  • All lis in ul :
    • Set the URL of the image and set it to appear only once (no repetition)
    • Position the image you need (left 0px and up and down 5px)
    • Put the text in the list with the padding-left property

List - Short-case properties

You can specify all list properties in a single property. This is called a short-case property.

Using short-case properties for lists, list style properties are set as follows:

ul {
list-style: square url("sqpurple.gif");
}

Try it out . . .

If the order in which the abbreviated property values are used is:

  1. list-style-type
  2. list-style-position (see CSS property sheet below for instructions)
  3. list-style-image

In short write properties, it doesn't matter if one of the above values is missing and the rest is still in the specified order.
