Please note that I am a developer, not a designer.
I need to separate card div for two columns in desktop mode. I mean "This should be in Left Side" should be display on left side and "This should be on right side" should be display on right side.
I use following HTML.
<div class="card">
<div class="card-header">
Featured
</div>
<div class="card-block">
<div class="col-md-4">
This should be in Left Side
</div>
<div class="col-md-8">
This should be on right side
</div>
</div>
</div>
If you want to test online here is the jsfiddle (https://jsfiddle.net/uxfjwhpc/1/).
What is my mistake and how to correct it?
