Since I keep forgetting this has been possible since the introduction of html 5: [WayBack] html – Is it possible to specify a starting number for an ordered list? – Stack Overflow:
If you need the functionality to start an ordered list (OL) at a specific point, you’ll have to specify your doctype as HTML 5; which is:
<!doctype html>With that doctype, it is valid to set a
startattribute on an ordered list. Such as:<ol start="6"> <li>Lorem</li> <li>Ipsum</li> <li>Dolor</li> </ol>
