Código final da aula:
Mobile first
Chegou a hora de usar os
pontos de ruptura, em inglês,
breakpoints, para adequar a tela do browser as configurações dos dispositivos (mobile, tablet, desktop, laptop, etc.).
O
bootstrap é
mobile first.
Isso que dizer que ele primeiro se preocupa com o formato de tela de celular, antes de qualquer outro dispositivo.
O
bootstrap prioriza a experiência de usuário
mobile.
Breakpoints
Breakpoints são "
coisinhas" como essas aí em baixo destacadas em
azul, escritas no
html do
bootstrap:
col-sm-
col-md-
col-lg-
col-xl-
- col - column
- md - medium
- lg - large
- xl - extra large
Para detalhes acesse a documentação:
https://getbootstrap.com.br/docs/4.1/layout/grid/
Vamos começar
deletando a
div Home que não iremos usar.
Em seguida, vamos fazer uma pequena alteração no
search.
É o que tá em
laranja no código abaixo.

Acesse:
Veja que agora, o
search ocupa toda a largura da tela quando você muda o tamanho da tela do browser, faça o teste.
É aí que o
breakpoint entra em ação.
Vamos adicionar os
breakpoints.
Adicione ao search
col-sm-2.

Acesse:
Faça o seguinte teste,
mude a
largura da
tela do browser com o mouse.
Veja que a
search agora ocupa toda a largura da tela quando a largura do browser tá em determinado limite de largura.
Quando ultrapassamos esse limite,
significa que
atingiu o
breakpoint, aí o
search fica menor, fica com tamanho
2 de
12, que é a largura total da tela do browser para o
bootstrap.
Essa configuração de
breakpoint não ficou legal, vamos mudar isso.
Vamos trocar o col-sm-2 para col-sm-12 e colocar o col-md-6

Acesse e teste novamente:
Agora começou a ficar um pouco melhor. ;)
Mas, note que quando você
aumenta a
largura da tela do
browser, o
search tá ficando muito grande ainda.
Vamos tentar melhorar isso então?
Coloque no
search:
col-lg-4

Acesse:
Faça o teste de novo.
Agora sim, vamos deixar a
search desse jeito por enquanto.
Divs Primeiro item, Segundo item e Terceiro item
Agora vamos mexer nas
divs que tem:
Primeiro item,
Segundo item e
Terceiro item.
A
div Terceiro item vai virar a
div Conteúdo da parte inferior.
Tire o estilo
style='min-height: 800px; dela, não queremos mais essa altura.
Vamos fazer o mesmo com o
Primeiro item também.
Ou seja, remova o
style='min-height: 800px; do
Primeiro item e do
Terceiro item.
Então, o
html vai ficar assim.

Acesse:
Porque aconteceu esse efeito?
Primeiro por causa do
col-12 e também porque o
primeiro item tá com
col-2, o
segundo com
col-8, e
8 + 2 = 10.
Como o
terceiro item, agora chamado de
Conteúdo da parte inferior, tá com
col-12, ele não vai caber na primeira linha, por isso, cai para segunda, mesmo sem criar uma nova
row. 🤔
Seguindo
Vamos agora chamar o
Primeiro item de
Conteúdo superior, e colocar ele no topo da página com:
col-12 col-lg-2

Acesse e teste:
Vamos agora copiar duas rows e colar dentro da Área do conteúdo principal.
Na primeira coluna a gente vai colocar
col-auto e na segunda
col-6.
O
col-auto se ajusta ao tamanho do texto, mude o texto:
A simple primary alert—check it out!
Para um texto menor qualquer e veja o resultado, perceba que ele se ajusta ao novo texto.
