                                            of the section counter */
  content: counters(section, ".") " ";   /* Combines the values of all instances
                                            of the section counter, separated
                                            by a period */

            <ol>
              <div class="white"><h3>White wines</h3></div>

                  </ol>
               </li>
            </ol>
               <ol>
              <li>Sauvinon Blanc ~
                     <ol>
                       <li>Fume blanc<span></span><em>&nbsp;</em></li>
                       <li>Kim crawford<span>( Malborough )$13/$42</span><em>&nbsp;</em></li>
                  </ol>
               </li>
            </ol>
           <ul>

Answer 3

Your question is answered here

Achieving sub numbering on ol items html

The following style sheet numbers nested list items as "1", "1.1", "1.1.1", etc.

OL { counter-reset: item }
OL>LI { display: block }
OL>LI:before { content: counters(item, ".") " "; counter-increment: item }

Maybe you can edit your question to avoid duplicating questions. Pointing to that one I just told you.

Answer 4

ol tag means ordered list (with numbers).

ul tag means unordered one.

Overlapping ol lists allow this kind of presentation : 1.1.2

<ol>
  <li>BLA-BLA-BLA
    <ol>
      <li> Bla-bla-bla.</li>
      <li> Bla-bla-bla.</li>
      <li> Bla-bla-bla.
        <ul>
          <li>lalal - balalala;</li>
        </ul>
      </li>
    </ol>
  </li>
</ol>
