title: JavaFX layout based on percentage of window size
body: <p>I need to create a Layout in JavaFX with 3 labels. Each label should be centered horizontally. The first should be placed 1/4 of the way down the window, the second should be halfway down (i.e. centered vertically) and the third should be 3/4 of the way down.</p>
  
  <p>The labels should keep their relative positions if the window is resized.</p>
  
  <p>It seems pretty simple, but I can't figure out how to do it. I tried with a VBox, but there doesn't seem to be a way to have fine control over the vertical placement. I then looked at AnchorPane, but couldn't see how to do this.</p>
  
  <p>Can someone show me an easy way to do this either with FXML or programmatically?</p>
