How to achieve decimal numbering in ordered lists? [duplicate]

Answer 1

Yes, this can be done with CSS Counters. However, it doesn't work on all browsers.

Answer 2

There's no cross-browser way of doing it.

The best you can achieve is nested ordered lists:

<ol>
    <li>Item 1
        <ol>
            <li>Subitem 1</li>
        </ol>
    </li>
</ol>

and then style each nested list to have a different type:

ol {
    list-style-type: upper-roman;
}
ol ol {
    list-style-type: decimal;
}

Hope this helps!
