CSS/Bootstrap Grid Row Alignment

Question

I can't understand why this nested grid row has the space above it. I want to align it to the center. I'd like to just select and align to center much like Excel.

I have a fluid container with a nested grid row with three columns and another grid row nested in the first column, but its like I've pressed return and there's a space above it.

TIA!

Answer 1

Don't use

<div class="container-fluid">

but use this

   <div class="col-12 d-flex justify-content-center">
     //like your code
   </div>

col-12 is only an example, change with the number that you want.
