For this assignment you need to create a ToDo list using Javascript, along with HTML and CSS.
Begin by creating a HTML page called todo.html. Then create a Javascript file called todo.js and link it in to the HTML page using a script tag. All Javascript for the assignment must be in the separate file. (For CSS, feel free to include styles in a style block at the top of the HTML page, or to link in CSS from a separate file).
On the todo.html page, create two blocks of content (see the attached diagram).
At the top of the page, create a HTML form with the label New Item.
Below the form, create a block with the label Item List. This block will initially be empty.
When the submit button in the form is clicked, a new sub-block of content ('item block') should be created containing the following:
Additional item blocks should be appended after the first item in the list. Item blocks should stack vertically.
