title: float property for inline element
body: <p>Can we apply float property to inline element? if we could, is there any difference between a floated inline-box and a floated block-box, like this two elements:</p>
  
  <pre><code>&lt;span style="float: left;"&gt;hello&lt;/span&gt;
  &lt;span style="float: left; display: block;"&gt;hello&lt;/span&gt;
  </code></pre>
  
  <p>thank you!</p>
