title: class overrule when two classes assigned to one div
body: <p>I was creating a <code>&lt;div&gt;</code> tag in which I wanted to apply two classes for a <code>&lt;div&gt;</code> tag which would be a thumbnail gallery. One class for its position and the other class for its style. This way I could apply the style, I was having some strange results which brought me to a question. </p>
  
  <p>Can two classes be assigned to a <code>&lt;div&gt;</code> tag? If so, which one overrules the other one or which one has priority?</p>
