For my first UI challenge, I created a Sign-up form. The challenge said it could be for anything I wanted, so I chose a form that sends information about good dogs. I used the font ruda and the blue #1D23AE as the accent color. The call to action is pill shaped button. The emergency exit is a smaller circle button marked with an X. I did not create the mockup.
