Suponha que temos um layout simples com duas colunas. Queremos que as colunas sejam divididas em 25%/75% para TODOS dispositivos.
Adicionaremos as seguintes classes às nossas duas colunas:
<div class="col-3">....</div>
<div class="col-9">....</div>
O exemplo a seguir resultará em uma divisão de 25%/75% em todos os dispositivos (extra pequeno, pequeno, médio, grande, xlarge e xxlarge).
<div class="container-fluid">
<div class="row">
<div class="col-3 bg-primary">
<p>Lorem ipsum...</p>
</div>
<div class="col-9 bg-dark">
<p>Sed ut perspiciatis...</p>
</div>
</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-4
e .col-8
( e para uma divisão de 50%/50%, você usaria .col-6
e .col-6
):
<!-- 33.3%/66.6% split -->

No Bootstrap 5, existe uma maneira fácil de criar colunas de largura igual para todos os dispositivos: basta remover o número de .col-*
e apenas use a classe .col
em um número especificado de elementos col. O Bootstrap reconhecerá quantas colunas existem e cada coluna terá a mesma largura:
<!-- Two columns: 50% width-->
<div class="row">
<div class="col">1 of 2</div>
<div class="col">2 of 2</div>
</div>
<!-- Four columns: 25% width-->
<div class="row">
<div class="col">1 of 4</div>
<div class="col">2 of 4</div>
<div class="col">3 of 4</div>
<div class="col">4 of 4</div>
</div>

<h1>Auto Layout Columns</h1>
<p>In Bootstrap 5, there is an easy way to create equal width columns for all devices: just use the <code>.col</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>
<div class="container-fluid">
<div class="row">
<div class="col bg-primary text-white p-3">1 of 2</div>
