so that there is my code, could someone please take the time to run it and help me answer three questions.

1. how do i change the color and size of the sign in text at the top left corner?
2. how do i reduce the size of the "x" buttons beside the EditText fields? (i want to make them really small)
3. How or Where can i get more colors like the full list of Color codes (if something like that exists)?


thank you for your help.
