title: How to only change left padding in javafx css
body: <p>I've used html+css quite a lot but I'm completely new to javafx+css. So this will be a newbie question but I can't find the answer anywhere.</p>
  
  <p>I have a large GridPane full of Labels (besides others). I can set padding for all these Labels like:</p>
  
  <pre><code>GridPane.containerLevel02 Label {
      -fx-padding: 0 0 0 5;
  }
  </code></pre>
  
  <p>This works. I want <strong>some of the labels to be more indented</strong> so I create the "leftIndent" class for them:</p>
  
  <pre><code>GridPane.containerLevel02 Label.leftIndent {
      -fx-padding: 0 0 0 20;
  }
  </code></pre>
  
  <p>This works too.</p>
  
  <p><strong>BUT</strong>, I don't want to specify the three zeros there because if I ever decide to add top/bottom padding to Labels in general, it will not affect the "leftIndent" labels.</p>
  
  <p>What I'm looking for is something like:</p>
  
  <pre><code>GridPane.containerLevel02 Label.leftIndent {
      -fx-padding-left: 20;
  }
  </code></pre>
  
  <p>... like in "normal" CSS or ...</p>
  
  <pre><code>GridPane.containerLevel02 Label.leftIndent {
      -fx-padding: null null null 20;
  }
  </code></pre>
  
  <p>...or anything that would let me <strong>specify left padding leaving the top, right and bottom padding untouched with whatever values they currently have</strong>.</p>
  
  <p>Is that possible? <strong>THANKS!</strong></p>
