Okay, can you describe to me in HTML code a form with the name and ID of options that has:
 - a slider input with a name and ID of volumeMusic that has a range between 0.0 and 1.0 
 - a slider input with a name and ID of volumeFX that has a range between 0.0 and 1.0 
 - a checkbox with a name and ID of isFullscreen that is unchecked by default

There should be no submit button or any button at all.  This concludes the Form.
Sure, here is an HTML code for the form:

<form>
  <div>
    <label for="volumeMusic">Volume Music:</label>
    <input type="range" name="volumeMusic" id="volumeMusic" min="0.0" max="1.0" step="0.1">
  </div>
  <div>
    <label for="volumeFX">Volume FX:</label>
    <input type="range" name="volumeFX" id="volumeFX" min="0.0" max="1.0" step="0.1">
  </div>
  <div>
    <label for="isFullscreen">Fullscreen:</label>
    <input type="checkbox" name="isFullscreen" id="isFullscreen">
  </div>
</form>
