Would this work?
.d-modal.login-modal .login-left-side, .d-modal.create-account .login-left-side {
display: none;
}
.d-modal.login-modal .d-modal__body, .d-modal.create-account .d-modal__body {
padding: 3px;
padding-right: -2px;
display: block;
}
That removes the left side of the modal and leaves you with just the right
