Signup form width too narrow / Submit button misaligned

[jjhampton]

Bug Report

What is the current behavior?

On desktop, signup form width is too narrow (around 300px), and submit button is too narrow and misaligned to the right. Seems to be an issue with the ordering / specificity of the CSS classes on the form and button. Strangely enough, I can't reproduce this issue on my local dev environment, but I see it on production. Leading me to think it might be a Webpack issue.

What is the expected behavior?

Form should have max-width of 500px (plus 10px padding on each side), button should be full-width of form and centered

What steps did you take to get this behavior?

Navigate to www.operationcode.org/signup .
