プログレスバー：progressとprogress-barとw-50

  <!-- divで、progressとprogress-barの組み合わせで実装する -->
  <!-- 進捗度は、aria-valuenowの値を変える -->
  <div class="progress mb-3">
    <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar" style="width: 20%" role="progressbar" aria-valuenow="25" aria-valuemin="0"
      aria-valuemax="100"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar w-50" role="progressbar" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar" style="width: 80%" role="progressbar" aria-valuenow="75" aria-valuemin="0"
      aria-valuemax="100"></div>
  </div>
  <div class="progress">
    <div class="progress-bar w-100" role="progressbar" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
  </div>

プログレスバーの色：progress-barとbg-*

  <div class="progress mb-3">
    <div class="bg-warning text-dark">progress-bar bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0"
      aria-valuemax="100"></div>
    <div class="bg-warning text-dark">progress-bar bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0"
      aria-valuemax="100"></div>
    <div class="bg-warning text-dark">progress-bar bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0"
      aria-valuemax="100"></div>
    <div class="bg-warning text-dark">progress-bar bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0"
      aria-valuemax="100"></div>
  </div>

20pxの太さのプログレスバー：style

  <!-- 高さはstyleで設定する -->
  <div class="progress" style="height: 20px;">
    <div class="progress-bar w-25" role="progressbar" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
  </div>

プログレスバーにテキストラベルを追加する

25%
  <div class="progress" style="height: 20px;">
    <!-- divにテキストを書くだけ -->
    <div class="progress-bar w-25" role="progressbar" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
  </div>

複数のプログレスバーを積み重ねる

  <div class="progress" style="height: 20px;">
    <div class="progress-bar" role="progressbar" style="width: 15%" aria-valuenow="15" aria-valuemin="0"
      aria-valuemax="100"></div>
    <div class="progress-bar bg-success" role="progressbar" style="width: 30%" aria-valuenow="30" aria-valuemin="0"
      aria-valuemax="100"></div>
    <div class="progress-bar bg-info" role="progressbar" style="width: 20%" aria-valuenow="20" aria-valuemin="0"
      aria-valuemax="100"></div>
  </div>

プログレスバーをストライプにする：progress-bar-striped

  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped" role="progressbar" style="width: 10%" aria-valuenow="10"
      aria-valuemin="0" aria-valuemax="100"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped bg-success" role="progressbar" style="width: 25%" aria-valuenow="25"
      aria-valuemin="0" aria-valuemax="100"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped bg-info" role="progressbar" style="width: 50%" aria-valuenow="50"

  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75"
      aria-valuemin="0" aria-valuemax="100"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100"
      aria-valuemin="0" aria-valuemax="100"></div>
  </div>

プログレスバーのアニメーションさせる：progress-bar-animated

  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="25"
      aria-valuemin="0" aria-valuemax="100" style="width: 25%"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped progress-bar-animated bg-success" role="progressbar"
      aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" style="width: 50%"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped progress-bar-animated bg-info" role="progressbar" aria-valuenow="75"
      aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
  </div>
  <div class="progress mb-3">
    <div class="progress-bar progress-bar-striped progress-bar-animated bg-danger" role="progressbar"
