Rows e Columns – Linhas e Colunas
A forma como o bootstrap enxerga o espaço no browser é parecido com uma planilha.
Planilha
Em uma planilha, você tem colunas de A, B, …, Z, AA, AB, AC, …, AZ …e C ∞.
E linhas 1, 2, 3, …∞
Apesar de parecido com uma planilha na analogia, o bootstrap funciona um pouco diferente.
Colunas(col)
O bootstrap funciona com um sistema de grade, por isso parece com uma planilha.
Esse sistema dele, permite até 12 colunas em uma página, não importa a largura da tela, ele sempre vai dividir o espaço em 12 pedaços.
É assim que ele formata o conteúdo na tela do browser.
Essas colunas podem ser usadas individualmente ou agrupadas.
Para agrupar as colunas, você precisa criar linhas.
Linha(row)
Para criar linhas, adicione uma div com class=”row”.
A quantidade de linhas não importa.
Vamos em frente, criaremos uma linha(row) dentro do dentro do container em /templates/bootstrap/example.html,dentro da row criaremos uma coluna(col) e dentro dessa col colocaremos o alert-primary.
/templates/bootstrap/example.html

Veja que nada mudou, porque só temos uma coluna, por isso, ela ocupou os 12 pedaços da tela, ou seja, a tela inteira.
Vamos adicionar um alert-secondary em uma segunda coluna na mesma linha para ver o que acontece.

Agora temos na primeira linha, duas colunas, uma com alert-primary e a outra com um alert-secondary.
A segunda linha com o alert-secondary ocupando toda a tela é do class=’container-fluid’.
Agora vamos criar 12 colunas ao todo, iguais a essas que criamos, ou seja, 12 colunas alternadas: alert-primary e alert-secondary.
Vamos adicionar um alert-secondary em uma segunda coluna na mesma linha para ver o que acontece.

Como não definimos o tamanho das colunas, ele fez uma formatação padrão.
As colunas podem ter tamanho de 1 a 12.
Vamos colocar todas as colunas com tamanho 1 para as 12 colunas ficarem na mesma linha.
