Bootstrap进度栏未显示在移动视图中

Question

I'm using this code for a progress bar and it's working fine on my laptop and on other desktop devices but in mobile view progress bar is not showing:

<div class="container">
<div class="progress ">
<div class="progress-bar progress-bar-striped active" role="progressbar"  aria-valuenow="0" aria-valuemin="0" aria-valuemax="0" style="width:0%">
</div>
</div>
 <div class="row progress-row"><div class="col-sm-6" style="text-align:    left;">$0</div>
 <div class="col-sm-6" style="text-align: right;">$29,000,000</div></div>                    
                       ICO STARTS IN 
 </div>

Answer 1

I changed your col-sm-6 classes to col-6 to prevent the labels from stacking on the smallest screens. The progress bar itself is showing up as expected on the smallest screens.
