      <h1>&lt;layflags-rolling-number&gt;<br /><span>Demo</span></h1>
      <p>
        &lt;layflags-rolling-number&gt; is an easy-to-use inline Web Component
        that shows a nice rolling digit animation and automatically adapts to
        the surrounding font style (family, color, size, etc.).
      </p>

      <h2>Playground</h2>
      <form id="form">
        <input type="number" name="number" value="123" size="6" />
        <button type="button" id="randomize">rnd</button>
        <button type="submit">set</button>
      </form>

      <div class="output">
        <layflags-rolling-number class="rolling" style="--roll-duration: 750ms"
          >123</layflags-rolling-number
        >°C
      </div>

      <p style="font-family: serif; font-style: italic">
        It's around
        <layflags-rolling-number class="rolling" style="--roll-duration: 1500ms"
          >123</layflags-rolling-number
        >°C at the moment!
      </p>

      <p></p>
