Forms
Our form setup doesn’t override the browser’s default form styles. You have to use our specific classes to benefit from these styles.
Familiarize yourself with the concept of a "form group". A form group is a container that should hold a label and a form element, and optionally a help text and an error text.
For buttons in forms, refer to the Buttons and links documentation.
                                Handy classes:
                                .form-group:
The container for label, input, help text and
                                validation
                                .form-control:
 Styling for inputs, selects, and text areas
                                .form-control-file:

                                .form-check:
 Like form group, but for checkbox and radio inputs and
                                labels
                                .form-check-input:
