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

Answer 1

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

The best you can achieve is nested ordered lists:

    
Item 1
        

            
Subitem 1
        
    

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!
