<h1>No gutters</h1>
<p>Use the .row-no-gutters class to remove the gutters from a row and its columns:</p>
<div class="row row-no-gutters">
<div class="col-sm-4" style="background-color:lavender;">.col-sm-4</div>
<div class="col-sm-8" style="background-color:lavenderblush;">.col-sm-8</div>
</div>
<br>
<p>And here's a row with gutters to demonstrate the differences:</p>
<div class="row">
<div class="col-sm-4" style="background-color:lavender;">.col-sm-4</div>
<div class="col-sm-8" style="background-color:lavenderblush;">.col-sm-8</div>
</div>
