WARNING: CSS Error parsing
<p>I am trying to create a GUI in JavaFx. My problem is that I am receiving warning with my CSS style. In fact my warnings are:</p>

<blockquote>
  <p>WARNING: CSS Error parsing '<em>{-fx-font: 90 Langdon; -fx-base: #AE3522; -fx-text-fill: white; bold;}: 
  WARNING: CSS Error parsing '</em>{-fx-font: 60 Langdon; -fx-text-fill: white; bold; -fx-base: #AE3522 bold;}: </p>
</blockquote>

<p>This CSS is assignig to my buttons and Labels:</p>

<pre><code>learnin = new Label(" Puzzle ");
learnin.setStyle("-fx-font: 90 Langdon; -fx-base: #AE3522; -fx-text-fill: white; bold;");
</code></pre>
