The CSS to create equal height borders.

@media (min-width: 768px)
{
  .row-relative { position: relative; }
  .col-border 
  { 
    padding-left: 0; 
    position: static; 
  }
  
  .col-border-padding { padding-left: 15px; }
  .col-border:before 
  {
    content: "";
    position: absolute;
    top: 0;
    bottom: 0;
    border-left: 1px solid red;
  } 
}

Create the equal height borders using CSS transforms instead.

@media (min-width: 768px)
{
	.row-relative { position: relative; }
	.col-border 
	{ 
		position: static; 
	}
	
	.col-border:before 
	{
		content: "";
		position: absolute;
		top: 0;
		bottom: 0;
		border-left: 1px solid red;
		transform: translateX(-15px);
	}	
}
