SVG や JavaScript を使用せずに CSS でアニメーション化された破線の境界線を作成する方法

<code class="css">.border {
  height: 100px;
  width: 200px;
  background: linear-gradient(90deg, blue 50%, transparent 50%),
              linear-gradient(90deg, blue 50%, transparent 50%),
              linear-gradient(0deg, blue 50%, transparent 50%),
              linear-gradient(0deg, blue 50%, transparent 50%);
  background-repeat: repeat-x, repeat-x, repeat-y, repeat-y;
  background-size: 16px 4px, 16px 4px, 4px 16px, 4px 16px;
  background-position: 0px 0px, 212px 116px, 0px 116px, 216px 0px;
  padding: 10px;
  transition: background-position 2s;
}
.border:hover {
    background-position: 212px 0px, 0px 116px, 0px 0px, 216px 116px;
}</code>

<code class="html"><div class="border">Some text</div></code>
