Referência de formulários CSS do Bootstrap
Configurações padrão do Bootstrap
Os controles de formulário individuais recebem automaticamente algum estilo global com o Bootstrap.
Todos os elementos textuais <input>, <textarea> e <select> com class="form-control" são definidos para largura: 100%; por padrão.
Regras padrão para todos os três layouts de formulário:
- Enrole etiquetas e controles de formulário
<div class="form-group">(necessário para espaçamento ideal) - Adicionar classe a todos os elementos
.form-controltextuais<input>,<textarea>e<select>
O exemplo a seguir cria um formulário Bootstrap simples com dois campos de entrada, uma caixa de seleção e um botão de envio:
