Předpokládejme, že máme jednoduché rozložení se dvěma sloupci. Chceme, aby byly sloupce rozděleny 25 %/75 % pro malá zařízení.
Malá zařízení jsou definována jako zařízení s šířkou obrazovky od 576 pixelů do 767 pixelů.
Pro malá zařízení použijeme třídy .col-sm-*.
Do našich dvou sloupců přidáme následující třídy:
<div class="col-sm-3">....</div>
<div class="col-sm-9">....</div>Následující příklad povede k rozdělení 25 %/75 % na malých (a středních, velkých, xlarge a xxlarge) zařízeních. Na extra malých zařízeních se automaticky složí (100 %):
<div class="container-fluid">
<div class="row">
<div class="col-sm-3 bg-primary">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-9 bg-dark">
<p>Sed ut perspiciatis...</p>
</div>
</div>

Poznámka: Ujistěte se, že součet je 12 nebo méně (není nutné použít všech 12 dostupných sloupců):
Pro rozdělení 33,3 %/66,6 % byste použili .col-sm-4 a .col-sm-8 (a pro rozdělení 50 %/50 % byste použili .col-sm-6 a .col -sm-6):

V Bootstrapu 5 existuje snadný způsob, jak vytvořit sloupce stejné šířky pro všechna zařízení: stačí odstranit číslo z .col-sm-* a použít pouze .col-sm na zadaném počtu prvků col. Bootstrap rozpozná, kolik je tam sloupců, a každý sloupec bude mít stejnou šířku.
Pokud je velikost obrazovky méně než 576 pixelů, sloupce se budou skládat vodorovně:
<!-- Two columns: 50% width on all screens, except for extra small (100% width) -->
<div class="row">
<div class="col-sm">1 of 2</div>
<div class="col-sm">2 of 2</div>
</div>
<!-- Four columns: 25% width on all screens, except for extra small (100% width)-->
<div class="row">
<div class="col-sm">1 of 4</div>
<div class="col-sm">2 of 4</div>
<div class="col-sm">3 of 4</div>
<div class="col-sm">4 of 4</div>

<h1>Responsive Auto Layout Columns</h1>
<p>In Bootstrap 5, there is an easy way to create equal width columns: just use the <code>.col-sm</code> class on a specified number of col elements. Bootstrap will recognize how many columns there are, and each column will get the same width.</p>
<p>On extra small screens (<strong>less than 576px</strong>), the columns will stack horizontally.</p>
