O que é Bootstrap?

Porisabellabeatriz1603@gmail.com

Bootstrap é um framework front-end que facilita a criação de páginas web bonitas, organizadas e responsivas. Ele reúne um conjunto de classes e componentes prontos, como botões, formulários, grids, alertas, cards e muito mais, que você pode aplicar diretamente no HTML para dar estilo e funcionalidade ao seu site — sem precisar escrever todo o CSS e JavaScript do zero.

Com Bootstrap, você ganha rapidez no desenvolvimento, um visual padronizado e páginas que se adaptam automaticamente a diferentes tamanhos de tela, como celulares, tablets e computadores.

QUESTÃO 1 - Criando um Card com Bootstrap

Você deve criar um card usando Bootstrap com uma imagem no topo, um título e um parágrafo de descrição. O card deve estar dentro de um container com margem superior.

Regras:

  • A imagem deve estar no topo do card.

  • O título deve ser: “Curso de HTML”

  • O parágrafo deve conter: “Aprenda a criar páginas web com HTML e CSS.”

  • Utilize classes do Bootstrap como card, card-body, card-title, card-text.

Passos:

  1. Estruture o HTML básico com Bootstrap via CDN.

  2. Crie um div com container mt-5.

  3. Dentro do container, adicione um div com a classe card.

  4. Adicione uma imagem no topo.

  5. Dentro do card-body, insira o título e o texto.

QUESTÃO 2 – Criando uma Barra de Navegação (Navbar)

Crie uma barra de navegação com Bootstrap contendo:

  • Um nome de marca à esquerda com o texto “MeuSite”

  • Dois links de navegação: “Início” e “Contato”

Regras:

  • Use a classe navbar com navbar-light e bg-light

  • A barra deve estar dentro de um container

  • Use o componente navbar com nav e nav-item

Passos:

  1. Estruture o HTML e insira o CDN do Bootstrap.

  2. Crie um nav com classes da navbar.

  3. Adicione o nome da marca com navbar-brand.

  4. Crie os links com nav-link.

QUESTÃO 3 – Criando um Formulário com Campo de Email e Badge

Você deve criar um formulário simples com:

  • Um campo para inserir email.

  • Um botão de envio.

  • Um badge ao lado do botão com o texto “Novo”.

Regras:

  • Use o componente de formulário do Bootstrap.

  • O badge deve ter a classe badge bg-primary.

  • O botão deve ter a classe btn btn-dark.

Passos:

  1. Crie a estrutura HTML básica com Bootstrap.

  2. Adicione um form com input do tipo email.

  3. Adicione um botão com btn btn-dark.

  4. Adicione um span com badge bg-primary ao lado do botão.

Exemplo:
