Sign Up form extends beyond the parent div

Hello,

I noticed the Sign Up form extends beyond the parent div’s background styling when I signed up earlier.

Steps to reproduce:

  1. Don’t be signed in.
  2. Visit https://www.codecademy.com/courses/react-101/lessons/react-jsx-intro/exercises/why-react?action=lesson_resume

Cause:
The parent div of the anonymous-user-wall div has a fixed height of 500 pixels.

More information:
Operating system: Windows 10
Browser: Chrome Version 59.0.3071.115 (Official build) (64-bits)
Extensions: None (all off)
