Intro component with sign-up form | newbie edition

hi, i just finished this challenge, for this one my focus was in try to make it as close to the design as posible, there are some details that my version lacks (my placeholder for the email error doesn't change of color on display) also my javascript skill are rudimentary i just started learning it a few weeks ago, soo if you want to take a look and give some feedback on my js code it will be a godsend, have a nice day
