title: Video JS - How to change the subtitle font size
body: <p>I am working with Video JS, which I am finding really great, though I have an issue since I can't change the font size of the subtitle text, when player is in full screen.</p>
  
  <p>What i have done is to change in the Video JS CSS file, the fon't size from 1.4em to 4em.</p>
  
  <pre><code>/* Individual tracks */
  .video-js .vjs-text-track {
    display: none;
    font-size: 1.4em;
    text-align: center;
    margin-bottom: 0.1em;
    /* Transparent black background, or fallback to all black (oldIE) */
    background: rgb(0, 0, 0); background: rgba(0, 0, 0, 0.50);
  }
  </code></pre>
  
  <p>But it doesn't work, it only changes the susbtitle font size when video player is not full screen.</p>
  
  <p>Can you please help me solve this problem. I am using Video JS version 4.1</p>
