Referencia de formularios CSS de Bootstrap
Configuración predeterminada de Bootstrap
Los controles de formulario individuales reciben automáticamente un estilo global con Bootstrap.
Todos los elementos textuales <input>, <textarea> y <select> con class="form-control" se establecen en ancho: 100%; por defecto.
Reglas estándar para los tres diseños de formulario:
- Envuelva las etiquetas y los controles de formulario
<div class="form-group">(necesario para un espacio óptimo) - Agregar clase a todos los elementos
.form-controltextuales<input>,<textarea>y<select>
El siguiente ejemplo crea un formulario simple de Bootstrap con dos campos de entrada, una casilla de verificación y un botón de envío:
