title: HTML: completely useless tag
body: <p>I need completely dumb tag which does absolutely nothing. <code>div</code> breaks line and I wouldn't like to use <code>span</code> because I will put another elements inside this dump tag and I'm not sure if span is designed to contain other elements.</p>
  
  <p>These two solutions came up to my mind:</p>
  
  <ol>
  <li>Use span anyway</li>
  <li>Use completely unused tag</li>
  </ol>
  
  <p>but im not sure how it would work in older browsers.</p>
  
  <p>PS: I already solved my problem by using divs, but I am still curious about this question.</p>
