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.
If your website has a Content Security Policy (CSP) which doesn't allow style-src 'unsafe-inline', then you won't be able to use inline style 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 element.style.width) or using custom CSS classes.
<div class="progress">
<div class="progress-bar w-75" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>Remove the <span> with .sr-only class from within the progress bar to show a visible percentage.
To ensure that the label text remains legible even for low percentages, consider adding a min-width to the progress bar.
