I am running a simple online check-in service with minimal requirement, basically it asks users to enter some name and numbers, there is a button to click on, and as a result, it shows some key code and instructions. I coded it myself, so i'ts not the best. I would like you to provide me a framework, ideally just in css that I can manually enter into html so it looks neat. Below you see screenshots of what I have done, I like to have it nicer and simpler. Just using css tag to make it look nice.
