確かに、説明したフォームのHTMLコードは次のとおりです。
<form>
  <label for = "volumemusic">ボリューム音楽：</label>
  <入力型= "range" min = "0.0" max = "1.0" step = "0.1" name = "volumemusic" id = "volumemusic">
  <br>
  <ラベル= "volumefx"> volume fx：</label>
  <入力型= "range" min = "0.0" max = "1.0" step = "0.1" name = "volumefx" id = "volumefx">
  <br>
  <label for = "isfullscreen">フルスクリーン：</label>
  <入力タイプ= "チェックボックス" name = "isfullscreen" id = "isfullscreen">
</form>

<form>
  <label for="volumeMusic">Volume Music:</label>
  <input type="range" min="0.0" max="1.0" step="0.1" name="volumeMusic" id="volumeMusic">
