BootstrapCSS Forms Reference
Bootstrap's Default Settings
Individual form controls automatically receive some global styling with Bootstrap.
All textual <input>, <textarea>,and <select> elements with class="form-control" are set to width: 100%; by default.
Standard rules for all three form layouts:
- Wrap labels and form controls in
<div class="form-group">(needed for optimum spacing) - Add class
.form-controlto all textual<input>,<textarea>, and<select>elements
The following example creates a simple Bootstrap form with two input fields, one checkbox, and a submit button:
