Riferimento ai moduli CSS di Bootstrap
Impostazioni predefinite di Bootstrap
I controlli dei moduli individuali ricevono automaticamente uno stile globale con Bootstrap.
Tutti gli elementi testuali <input>, <textarea> e <select> con class="form-control" sono impostati su width: 100%; per impostazione predefinita.
Regole standard per tutti e tre i layout dei moduli:
- Avvolgi le etichette e i controlli dei moduli
<div class="form-group">(necessari per una spaziatura ottimale) - Aggiungi classe a tutti gli elementi
.form-controltestuali<input>,<textarea>e<select>
L'esempio seguente crea un semplice modulo Bootstrap con due campi di input, una casella di controllo e un pulsante di invio:
