How to make a transparent gap between columns?

Question

css

Good afternoon.
I'm just learning layout with Bootstrap.
Can you please tell me how to achieve such transparent gaps?

<div class="row">
           <div class="col-md-2"><img src="icon.png" alt=""><span>Текст</span></div>
           <div class="col-md-2"><img src="icon.png" alt=""><span>Текст</span></div>
           <div class="col-md-2"><img src="icon.png" alt=""><span>Текст</span></div>
           <div class="col-md-2"><img src="icon.png" alt=""><span>Текст</span></div>
           <div class="col-md-2"><img src="icon.png" alt=""><span>Текст</span></div>
           <div class="col-md-2"><img src="icon.png" alt=""><span>Текст</span></div>
               
</div>

Answer 1

Throw out your bootstrap, and change the classes to your own, because I'm too lazy to rename them

Answer 2

play around with margins and padding
