List with decimal numbers

Question

is it possible to have <li> numbers like this?:

1.1 First Item
1.2 Second Item
2.1 Other item

Answer 1

The proper way to do it is by using the CSS counter-increment property.
You could set sections and sub-sections as "Section 1", "1.1", "1.2", etc.

<style>
    ol { counter-reset: item }
    li { display: block }
    li:before { content: counters(item, ".") " "; counter-increment: item }
</style>

   <ol>
        <li>First level</li>
        <li>First level 2
            <ol>
                <li>Second level</li>
                <li>Second level 2
                    <ol><li>Third level</li></ol>
                </li>
            </ol>
        </li>           
    </ol>
