Implementar menu com apenas CSS

[ppKrauss]

A versão atual permanece sem menu, o que é uma falha para a proposta desse primeiro rascunho.
Usar menu da tag <nav> do website corrente, se um CSS melhor por hora não for encontrado.

        <nav>
          <div class="nav-mobile"><a id="nav-toggle" href="#!"><span></span></a></div>
          <ul class="nav-list">
            <li>
              <a href="#!">Address For All</a>
              <ul class="nav-dropdown">
                <li><a href="/quemsomos">Quem Somos</a></li>
                <li><a href="/projetos">Projetos</a></li>
                <li><a href="/estatuto">Estatuto</a></li>
              </ul>
            </li>
            <li>
              <a href="#!">Dados & API</a>
              <ul class="nav-dropdown">
                <li><a href="/dados">Dados</a></li>
                <li><a href="/servicos">Serviços</a></li>
                <li><a href="/api">API</a></li>
              </ul>
            </li>
            <li>...</li>
          </ul>
        </nav>
