title: How to remove this gray top border in JavaFX TextArea
body: <p>I want a textarea that is completely with no borders and no background effects. Just plain white. I tried removing the border and background but there is this weird gray border that stays on top of the textarea. </p>
  
  <p><img src="https://i.stack.imgur.com/8jc5b.jpg" alt="enter image description here"></p>
  
  <p>Under the  "complaints" word there, that is a text area. I removed everything but still that gray line stays.</p>
  
  <pre><code>textArea.setStyle("-fx-background-color: #fff; -fx-border-color: #fff; -fx-border-width: 0; -fx-border-image-width: 0; -fx-background-image: null; -fx-region-background: null;-fx-border-insets: 0; -fx-background-size:0; -fx-border-image-insets:0;");
  </code></pre>
