title: What is the proper HTML entity for the "x" in a dimension?
body: <p>Is the proper HTML entity for giving dimensions <code>&amp;times;</code>? I want to be semantically correct, but that begs the question, is listing a dimension as <code>2" x 3"</code> even semantic? If the <em>x</em> represents "by", would I use the letter x or &times;?</p>
  
  <p>In my code I've been using <code>2&amp;Prime;&amp;nbsp;&amp;times;&amp;nbsp;3&amp;Prime;</code>, or 2&Prime;&nbsp;&times;&nbsp;3&Prime;. The non-breaking spaces are to prevent the dimension from being wrapped, as per the suggestions found in <a href="http://webtypography.net/Rhythm_and_Proportion/Etiquette_of_Hyphenation_and_Pagination/2.4.6/">The Elements of Typographic Style Applied to the Web</a>.</p>
