The Signup container is given the styles of font color as #fff, background color as #405e9e, and box-shadow style of 0px 2px 2px rgba(0, 0, 0, 0.3). The title of the form is displayed with the styles of font-size as 26px, font-weight as bold, and text-align as center. The input text fields are validated by making them required fields and given a border color as #dfdfdf.
