title: Is a wrapper <div> a violation of content-style separation?
body: <p>It's been said that the goal of CSS is to provide visual presentation and the goal of HTML is to provide structure of the document. Well, thank goodness. It has gotten so much easier, especially compared to font tags! </p>
  
  <p>But in practice, it seems that way many of us still rely on HTML to use CSS when it shouldn't be there. For example, it's common to see a <code>&lt;div id="wrapper"&gt;</code> to wrap around elements inside so the body can be centered. In pure HTML, it would never be used because it's meaningless and it's used ONLY for CSS. </p>
  
  <p>Right? So doesn't using <code>&lt;div id="wrapper"&gt;</code> actually violate one of the fundamentals of content-presentation separation?</p>
