        progress += Math.random() * 20;
        f7.progressbar.set(progressBarEl, progress);
        if (progressBefore < 100) {

      In addition to
      <a href="/preloader/">Preloader</a>, Framework7 also comes with fancy animated determinate and
      infinite/indeterminate progress bars to indicate some activity.

    <p>
      When progress bar is determinate it indicates how long an operation will take when the
      percentage complete is detectable.
    </p>
    <p>Inline determinate progress bar:</p>
    <div>
      <p>
        <Progressbar progress={10} id="demo-inline-progressbar" />
      </p>
      <!-- prettier-ignore -->
      <Segmented raised>
        <Button onClick={() => setInlineProgress(10)}>10%</Button>
        <Button onClick={() => setInlineProgress(30)}>30%</Button>
        <Button onClick={() => setInlineProgress(50)}>50%</Button>
        <Button onClick={() => setInlineProgress(100)}>100%</Button>
      </Segmented>
    </div>
    <!-- prettier-ignore -->
    <div>
      <p>Inline determinate load & hide:</p>
      <p id="demo-determinate-container"></p>
      <p>
        <Button fill onClick={() => showDeterminate(true)}>Start Loading</Button>
      </p>
    </div>
    <!-- prettier-ignore -->
    <div>
      <p>Overlay with determinate progress bar on top of the app:</p>
      <p>
        <Button fill onClick={() => showDeterminate(false)}>Start Loading</Button>
      </p>
    </div>
  </Block>
  <BlockTitle>Infinite Progress Bar</BlockTitle>
  <Block strongIos outlineIos>
    <p>
      When progress bar is infinite/indeterminate it requests that the user wait while something
      finishes when it’s not necessary to indicate how long it will take.

    <p>
      <Progressbar infinite />
