How do I adjust the width of responses and "Other" option so that is not cutoff?

Hi,

Injecting the following CSS codes to your form should extend all the other text boxes on checkbox and radio.

.form-textbox.form-radio-other-input,
.form-textbox.form-checkbox-other-input {
width: 180px;
max-width: 180px;
}

.form-radio-item:last-child,
.form-checkbox-item:last-child {
width: 230px !important;
max-width: 230px;
}
