bootstrap center progressbar on div - html

Question

I'm trying to use a Bootstrap progress bar as a loading indicator, and I want the progress bar to be a certain width with the whole thing centered in the DIV. But the progress bar doesn't seem to like being centered.
When I do:
<div class="text-center">
<img src="~/Content/Images/loading.gif" style="height:80px;" />
</div>
The image is centered properly. But when I substitute it for a progress bar, it goes to the left:
<div class="text-center">
<div class="progress" style="width:200px;"> <!-- set to certain width -->
<div class="progress-bar progress-bar-striped active" role="progressbar" style="width: 100%;">
<span>
Loading...
</span>
</div>
</div>
</div>

Answer 1

This bit of css worked for me.
.progress { margin-left: auto; margin-right:auto; }

Answer 2

Or, you can just use Bootstrap's center-block class
<div class="text-center">
<div class="progress center-block" style="width:200px;"> <!-- set to certain width -->
<div class="progress-bar progress-bar-striped active" role="progressbar" style="width: 100%;">
<span>
Loading...
</span>
</div>
</div>
</div>

Just want to enhance the Marcelo answer, for those who are new to CSS (like me)
Remember to check the class in which your progress bar is located:
For me the progress bar was in "download > progress" class like:
<div id="download" class="download">
<div class="container">
<div class="row">
<div class="col-md-12">
<div id="main_slider" class="carousel slide banner-main" data-ride="carousel">
<div class="carousel-inner">
<div class="carousel-item active">
<h3>Programming languages 1</h3>
<div class="progress" style="width: 50%">
So in my style.css I have added Marcelo answer, below the download css like this
.download {
padding-top: 90px;
padding-bottom: 90px;
background: #fff;
}
.download .progress { margin-left: auto; margin-right:auto; }
and it worked, so do not be afraid of CSS, keep on taking Panga(challenges) with code ;)
