I need help with an HTML/CSS project that operates as a shopping cart.

1.) The page should contain at least one select box to contain categories, and one table/select box for items

2.) The user will select the category from the select box, then the table/select box will be filled with items based on the first selection.

3.) The user will select an item to be added to the cart

4.) Add functionality to remove, edit or delete to the cart

5.) Create a button to display the content of the cart with option to continue shopping

6.) On exist, ask for the customer info, such as name, address,

7.) Store any of the select boxes items in a flat file stored locally "C:\ShopingCart.txt"

8.) The client must be JavaScript (You can use JQuery or any other library) The back end can be one of the following:-

Page_load, Web-method, or WEB API 2

The database / storage must be included in app_data folder
