Need help fixing contact page

I’m having issues with my contact page, there are some problems with the steps in the contact page. Between it not scrolling on mobile for responsiveness, to the typing text not being colored correctly to see whats going on, and interaction problems between choppiness and glitches. Could someone take a look and let me know what I’m doing wrong to cause this. I’ve been working on this for a day and a half. The page is “New Contact”. I really want this site done, as I’ve been on it for months.
