Bootstrap Grid - Square Tiles with same horizontal/vertical gap

问题

I'm trying to create a Grid of Tiles with Bootstrap with the following properties:

all tiles should be squares
horizontal and vertical gaps should be the same (even the same compared on different screen-widths)
the tiles should always be centered in the middle of the screen(distance from the left edge of website to the left border of the leftmost tile = distance from the right edge of the website to the right border of the righmost tile)

It should look like this:

body{
	   background: #a5b5c5;
	   background:lightblue !important;
    }

    .box{
	   height: 180px;
	   width: 180px;
	   background: #fff;
	   border-radius: 4px;
    }

    .col-lg-2, .col-md-3, .col-xs-6{
	     margin-top: 12px !important;
    }

<div class="container">
	<div class="row">
		
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
		<div class="col-lg-2 col-md-3 col-xs-6 ">
			<div class="box"></div>
		</div>
  	</div>
</div>

What should I do to accomplish a responsiveness which sustains my properties?

Thanks!!

You didn't mention specific box dimensions, only that they should remain square. In that case, use margin-top:30px to corresponding with the Bootstrap gutter width, and padding-bottom: 100%; on the box.

.box {
   background: #fff;
   border-radius: 4px;
   padding-bottom: 100%;
}

.col-lg-2, .col-md-3, .col-xs-6{
    margin-top: 30px !important;
}

Bootstrap 3 demo
Bootstrap 4 demo

Note: Setting a px size on the .box (ie:width:180px;height:180px) will prevent the boxes from resizing responsively.

You can increase the gutter by changing margins and padding. Margin is double the padding for example...

.col-lg-2, .col-md-3, .col-xs-6{
    padding-left: 30px;
    padding-right: 30px;
    margin-top: 60px;
}

    body{

    }
    .box{
        height: 100px;
        background: #fff;
        border-radius: 5px;
        margin-bottom: 10px;
        max-width: 100px;
    }
