title: Bootstrap Holder.js Length of "text:" string
body: <p>I am using default settings for Holder.js.
  I want to specify a place-holder image of dimension 100x110 with text "Image Not Available":</p>
  
  <pre><code>&lt;img data-src="holder.js/100x110/social/text:Image Not Available" /&gt;
  </code></pre>
  
  <p>When I do this, the text string is on one line (centred vertically and horizontally) and ends up being truncated.  It then shows as: "nage Not Availab".</p>
  
  <p>Please, is there some trick to getting a "line break" into the text, so that (space permitting and font-size being correct) the text will flow over multiple rows within the place-holder, like this:</p>
  
  <pre><code>Image Not
  Available
  </code></pre>
  
  <p>or</p>
  
  <pre><code> Image
    Not
  Available
  </code></pre>
  
  <p>Thank you.</p>
