Suponha que temos um layout simples com duas colunas. Queremos que as colunas sejam divididas em 25%/75% para dispositivos pequenos.
Dispositivos pequenos são definidos como tendo uma largura de tela de 576 pixels a 767 pixels.
Para dispositivos pequenos usaremos as classes .col-sm-*.
Adicionaremos as seguintes classes às nossas duas colunas:
<div class="col-sm-3">....</div>
<div class="col-sm-9">....</div>O exemplo a seguir resultará em uma divisão de 25%/75% em dispositivos pequenos (e médios, grandes, xlarge e xxlarge). Em dispositivos muito pequenos, ele será empilhado automaticamente (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>

Observação: certifique-se de que a soma seja 12 ou menos (não é necessário usar todas as 12 colunas disponíveis):
Para uma divisão de 33,3%/66,6%, você usaria .col-sm-4 e .col-sm-8 (e para uma divisão de 50%/50%, você usaria .col-sm-6 e .col -sm-6):
<!-- 33.3/66.6% split: -->
<div class="container-fluid">
<div class="row">
<div class="col-sm-4 bg-primary">

No Bootstrap 5, existe uma maneira fácil de criar colunas de largura igual para todos os dispositivos: basta remover o número de .col-sm-* e usar apenas a .col-sm em um número especificado de elementos col. O Bootstrap reconhecerá quantas colunas existem e cada coluna terá a mesma largura.
Se o tamanho da tela for menor que 576px, as colunas serão empilhadas 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>
<div class="container-fluid">
<div class="row">
<div class="col-sm bg-primary text-white">1 of 2</div>
