What did I learn today 4

What did I learn at this hour?
In my fourth lesson, I've learnt how to create a website, from making it detect usernames and passwords. Also, as we've seen in places like McDonald's where there are "machines" that you can use to select what you want to buy, here gave me the opportunity of learning how to give options to users, like lists, range, number, checkbox and radio. Last but not less important, a textarea, is a text input field that has a customizable area.
