Answer 1

i’m not sure I understand what you mean. When I run the code, tapping the text box makes the whole thing blink in shadow momentarily, and an X slowly appears slightly off center. is the shadow missing inside the checkbox the problem, or did you actually want the whole thing to go into shadow slowly rather than blinking?

Answer 2

Outside shadow's transition 1s.
