Can you count a particular class with CSS?

Question

Lets say I have a simple list like so:

    
one
    
two
    &l         


        

Answer 1

Giving display: block to the li elements without .count class is also working.

ul {
    list-style-type:decimal;
    padding-left: 30px;
}
li:not(.count) {
    display: block;
}

Working Fiddle

For older browsers:

ul {
    list-style-type:decimal;
    padding-left: 30px;
}
li {
    display: block;
}
li.count {
    display: list-item;
}

Working Fiddle

Another way, if you are planning to change the display state of all li elements, use :after/:before pseudo classes with display as list-item.
