Payment Page - Credit Card Checkout

The screenshot for a checkout system credit card payment interface being coded. A work in progress. I am coding the UI design created by Stanley Huang into a real web page.

This is being created using html5, CSS, CSS selectors, CSS linter, semantic classnames, alphabetized CSS, flexbox, no use of !important, Atom, reduced style redundancies and git. Later Cleave.js, Jquery and/or PHP maybe utilized.

The project can be followed on GitHub at: https://github.com/Katdelorme/Payment-Page
The page itself can be seen on: http://katherinedelorme.com/paymentpage/index
