How to center the fields and the button too

Please insert this custom CSS code to align the fields to center:

#cid_4, #cid_7, #cid_8, #cid_12, #cid_15 {
text-align: center !important;
}

.form-input .form-error-message, .form-input-wide .form-error-message {
max-width: 315px !important;
margin: 0 auto !important;

}

.form-pagebreak-back-container, .form-pagebreak-next-container {
float: none !important;
}
