Supongamos que tenemos un diseño simple con dos columnas. Queremos que las columnas se divida 25%/75% para dispositivos pequeños.
Los dispositivos pequeños se definen como aquellos que tienen un ancho de pantalla de 576 píxeles a 767 píxeles.
Para dispositivos pequeños usaremos las clases .col-sm-*.
Agregaremos las siguientes clases a nuestras dos columnas:
<div class="col-sm-3">....</div>
<div class="col-sm-9">....</div>El siguiente ejemplo dará como resultado una división del 25%/75% en dispositivos pequeños (y medianos, grandes, extragrandes y extragrandes). En dispositivos muy pequeños, se acumulará automáticamente (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>

Nota: Asegúrese de que la suma sume 12 o menos (no es necesario que utilice las 12 columnas disponibles):
Para una división del 33,3%/66,6%, usaría .col-sm-4 y .col-sm-8 (y para una división del 50%/50%, usarías .col-sm-6 y .col -sm-6):
<!-- 33.3/66.6% split: -->

En Bootstrap 5, hay una manera fácil de crear columnas de igual ancho para todos los dispositivos: simplemente elimine el número de .col-sm-* y solo use la .col-sm en un número específico de elementos col. Bootstrap reconocerá cuántas columnas hay y cada columna tendrá el mismo ancho.
Si el tamaño de la pantalla es menos de 576 px, las columnas se apilarán horizontalmente:
<!-- 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>
