Answer 1

Are you want space between the textbox? i mean in small device it having in two row .so there is add mt-3 (margin-top) for below margin to each input-group

Is this issue?

Add mt-3(margin-top) to each input-group and also add a width to span for correct alignment like this span{width:130px;}

 span{ width:130px; }

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <div class="container-fluid"> <div class="row"> <div class="input-group col-12 mt-3"> <span class="control-label d-flex h-100 align-items-center">Product Name* &nbsp;</span> <input type="text" class="form-control" placeholder="Product Name" id="productname" required> </div> <div class="input-group col-12 mt-3" style=> <span class="control-label d-flex h-100 align-items-center">Short Name* &nbsp;</span> <input type="text" class="form-control"placeholder="ShortName" id="shortname" required> </div> </div> </div>

Answer 2

You may use margin or padding class on your span element :

example

 <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.0/css/bootstrap.min.css" rel="stylesheet" /> <div class="row col-lg-12 col-sm-12"> <div class="input-group col-md-8"> <span class="control-label px-1">Product Name*</span> <input type="text" class="form-control" placeholder="Product Name" id="productname" required> </div> <div class="input-group col-md-4" style=> <span class="control-label px-1">Short Name*</span> <input type="text" class="form-control" placeholder="ShortName" id="shortname" required> </div> </div>

Spacing

Bootstrap includes a wide range of shorthand responsive margin and padding utility classes to modify an element's appearance.

How it works

Assign responsive-friendly margin or padding values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from .25rem to 3rem.
