I am developing a website and the grid bootstrap is not working ... the MD and SM are working properly, but when I test the responsiveness of the site XL does not work .. the images are one below the other instead of staying two per line.
<div class="container">
<h2>Parceiros</h2>
<div class="row">
<div class='col-xs-6 col-sm-2 col-md-2 wow bounceInLeft'><img src="img/parceiros/1.png" alt="" class="img-fluid"></div>
<div class='col-xs-6 col-sm-2 col-md-2 wow bounceInLeft'><img src="img/parceiros/2.png" alt="" class="img-fluid"></div>
<div class='col-xs-6 col-sm-2 col-md-2 wow bounceInRight'><img src="img/parceiros/4.png" alt="" class="img-fluid"></div>
<div class='col-xs-6 col-sm-2 col-md-2 wow bounceInRight'><img src="img/parceiros/5.png" alt="" class="img-fluid"></div>
<div class='col-xs-6 col-sm-2 col-md-2 wow bounceInLeft'><img src="img/parceiros/3.png" alt="" class="img-fluid"></div>
