Overview

The challenge

Users should be able to:

• View the optimal layout for the app depending on their device's screen size
• See hover states for all interactive elements on the page
• Create, read, update, and delete invoices
• Receive form validations when trying to create/edit an invoice
• Save draft invoices, and mark pending invoices as paid
• Filter invoices by status (draft/pending/paid)
• Toggle light and dark mode
• Bonus: Keep track of any changes, even after refreshing the browser (localStorage could be used for this if you're not building out a full-stack app)
