This code includes a form for registration and user login to your account. This form has a clear theme and switching between login and registration is done by moving the right and left parts of the form. This beautiful effect causes the relevant form to be displayed with just one click instead of two long and consecutive forms. Both of these forms have the appearance of depressions in some places, which makes the form different and more beautiful.
