How can you customize the numbers in an ordered list?

How can I left-align the numbers in an ordered list?

1.  an item
// skip some items for brevity 
9.  another item
10. notice the 1 is under the 9, and the item contents also line up

Change the character after the number in an ordered list?

1) an item

Also is there a CSS solution to change from numbers to alphabetic/roman lists instead of using the type attribute on the ol element.

I am mostly interested in answers that work on Firefox 3.

Borrowed and improved Marcus Downing's answer. Tested and works in Firefox 3 and Opera 9. Supports multiple lines, too.

ol {
    counter-reset: item;
    margin-left: 0;
    padding-left: 0;

li {
    display: block;
    margin-left: 3.5em;          /* Change with margin-left on li:before.  Must be -li:before::margin-left + li:before::padding-right.  (Causes indention for other lines.) */

li:before {
    content: counter(item) ")";  /* Change 'item' to 'item, upper-roman' or 'item, lower-roman' for upper- and lower-case roman, respectively. */
    counter-increment: item;
    display: inline-block;
    text-align: right;
    width: 3em;                  /* Must be the maximum width of your list's numbers, including the ')', for compatability (in case you use a fixed-width font, for example).  Will have to beef up if using roman. */
    padding-right: 0.5em;
    margin-left: -3.5em;         /* See li comments. */

The CSS for styling lists is here, but is basically:

li {
    list-style-type: decimal;
    list-style-position: inside;

However, the specific layout you're after can probably only be achieved by delving into the innards of the layout with something like this (note that I haven't actually tried it):

ol { counter-reset: item }
li { display: block }
li:before { content: counter(item) ") "; counter-increment: item }

You can also specify your own numbers in the HTML - e.g. if the numbers are being provided by a database:

  <li seq="1">Item one</li>
  <li seq="20">Item twenty</li>
  <li seq="300">Item three hundred</li>

The seq attribute is made visible using a method similar to that given in other answers. But instead of using content: counter(foo), we use content: attr(seq):

ol {
  list-style: none;

ol > li:before {
  content: attr(seq) ". ";
