Skip ordered list item numbering

Question

I have an ordered list and I'd like to skip the number output from a particular item.

Traditional output:

1. List item
2. List item
3. List item
4. List item
5. List item

Desired output:

1. List item
2. List item
   Skipped list item
3. List item
4. List item
5. List item

Is this achievable in CSS? I discovered an <ol> "start" attribute that I didn't know about before, but doesn't seem to help me.

Answer 1

The simplest way is to remove the list marker from the item to be skipped and set the number of the next item using the value attribute (which will not be deprecated/obsolete in HTML5). Example:

<ol>
<li>List item
<li>List item
<li style="list-style-type: none">List item
<li value=3>List item
<li>List item
</ol>

Answer 2

Another option is to use CSS3 counters: demo

HTML

<ul>
<li>One</li>
<li>Two</li>
<li class="skip">Skip</li>
<li>Three</li>
<li>Four</li>
</ul>​

CSS

ul {
    counter-reset:yourCounter;
}
ul li:not(.skip) {
    counter-increment:yourCounter;
    list-style:none;
}
ul li:not(.skip):before {
    content:counter(yourCounter) ".";
}
ul li.skip:before {
    content:"\a0\a0\a0"; /* some white-space... optional */
}
