  <div class="bs-callout bs-callout-danger" id="callout-progress-animation-css3">
    <h4>Cross-browser compatibility</h4>
    <p>Progress bars use CSS3 transitions and animations to achieve some of their effects. These features are not supported in Internet Explorer 9 and below or older versions of Firefox. Opera 12 does not support animations.</p>

    <h4 id="callout-progress-csp">Content Security Policy (CSP) compatibility</h4>
    <p>If your website has a <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP">Content Security Policy (CSP)</a> which doesn't allow <code>style-src 'unsafe-inline'</code>, then you won't be able to use inline <code>style</code> attributes to set progress bar widths as shown in our examples below. Alternative methods for setting the widths that are compatible with strict CSPs include using a little custom JavaScript (that sets <code>element.style.width</code>) or using custom CSS classes.</p>
