Progress Bars

What is progress bar?
  • The purpose of progress bars is to show that assets are loading, in progress, or that there is action taking place regarding elements on the page.
  • These features are not supported in Internet Explorer 9 and below or older versions of Firefox.
  • Opera 12 does not support animations

Default Progress Bar

  • Inside the empty <div> tag to create another <div> tag with a class of .progress-bar
  • To define the style attributes with the width expressed as a percentage(for example style=”60%”)
  • That 60% indicates the progress bar level
