Now that our <b>LoginController</b> is loaded up in our application, it's the perfect time to give it some nice design. First we start by centering the Instagram logo at the very top with a blue background behind it. Then we borrow the <b>UITextField</b> and <b>UIButton</b> components from our <b>SignUpController</b>. Lastly, I want to introduce the stylized attributed text for our button at the very bottom. While we're at it, let's also use a similar button in <b>SignUpController</b> to pop back to our login screen.
