How to spell bam correctly?

Question

HTML

<div c;ass="menu">
    <div class="menu__icon">
                   <span></span>
                   <span></span>
                   <span></span>
               </div>
         </div>
</div>

По правилам методологии БЭМ мне нужно для каждого span задать класс  или в css можно прописать "menu__icon span"?

Answer 2

As far as I understand it would be better like this:

<div class="menu">
    <div class="menu__icon">
                   <span class="menu__span"></span>
                   <span class="menu__span"></span>
                   <span class="menu__span"></span>
               </div>
         </div>
</div>
