Bootstrap 5: grade empilhada na horizontal

Índice

Exemplo de grade: empilhado na horizontal

Vamos criar um sistema de grade básico que começa empilhado em dispositivos muito pequenos, antes de se tornar horizontal em dispositivos maiores.

O exemplo a seguir mostra um layout simples de duas colunas "empilhado na horizontal", o que significa que resultará em uma divisão de 50%/50% em todas as telas, exceto nas telas extras pequenas, que serão empilhadas automaticamente (100%):

col-sm-6

Exemplo: empilhado na horizontal

<div class="container-fluid">
  <div class="row">
    <div class="col-sm-6 bg-primary">
      <p>Lorem ipsum...</p>
    </div>
    <div class="col-sm-6 bg-dark">
      <p>Sed ut perspiciatis...</p>
    </div>
  </div>
</div>

<div class="container-fluid mt-3">
  <h1>Grid Example</h1>
  <p>This example demonstrates a 50%/50% split on small, medium, large, xlarge and xxlarge devices. On extra small devices, it will stack (100% width).</p>      
  <p>Resize the browser window to see the effect.</p> 
  <div class="row">
    <div class="col-sm-6 bg-primary text-white p-3">
      Lorem ipsum...
    </div>
    <div class="col-sm-6 bg-dark text-white p-3">
      Sed ut perspiciatis...
    </div>
  </div>
</div>

</body>
</html>

Dica: os números nas classes .col-sm-* indicam quantas colunas o div deve abranger (de 12). Portanto, .col-sm-1 abrange 1 coluna, .col-sm-4 abrange 4 colunas, .col-sm-6 abrange 6 colunas, etc.

Observação: certifique-se de que a soma seja 12 ou menos (não é necessário usar todas as 12 colunas disponíveis):

Dica: você pode transformar qualquer layout de largura total em um layout de largura fixa responsivo, alterando o < code class="w3-codespan">.container-fluid classe para .container:

Exemplo: contêiner responsivo

<div class="container">
  <div class="row">
    <div class="col-sm-6">
      <p>Lorem ipsum...</p>
    </div>
    <div class="col-sm-6">
      <p>Sed ut perspiciatis...</p>
    </div>
  </div>
</div>

Colunas de layout automático

No Bootstrap 5, existe uma maneira fácil de criar colunas de largura igual para todos os dispositivos: basta remover o número de .col-size-* e use apenas a classe .col-size em um número especificado de elementos col. O Bootstrap reconhecerá quantas colunas existem e cada coluna terá a mesma largura. As classes de tamanho (sm, md, etc.) determinam quando as colunas devem responder:

<!-- 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>
</div>

1 of 2

2 of 2

1 of 4

2 of 4

3 of 4

4 of 4

  <h1>Auto Layout Columns</h1>
  <p>In Bootstrap 5, there is an easy way to create equal width columns: just use the <code>.col-size</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>Two columns: 50% width on all screens, except for extra small (100% width on screens less than <strong>576px</strong> wide)</p>
