These are files for teaching students about HTML forms.
Probably all you need to know is on the index page.
##Files
Scripts are unique to each HTML page, so look in the /scripts/ folder for a filename that matches the filename of the HTML. For example, checkboxes.html and checkboxes.js.
The CSS for the form elements is in styles/form.css. All the other CSS is in styles/styles.css.
The jquery.min.js file is included so you can run everything offline if need be.
##Parsley.js
There are two files included from Parsley.js, a useful jQuery library for form validation. I did not write these! They are only used by one file here, validation.html.
##Server-side validation
There's no server-side anything here. Interaction between forms and servers is discussed in action.html (a file that has no .js file).
##License
You are free to use and/or modify anything here.
