Exercise #1 - Incorrect CSS file

[ThumbSnail]

The CSS file linked to in Exercise 1 yields the following look. (And renders actions like deleting a ToDo impossible since there's no delete button to click on.)

It's because that CSS file is using class selectors (ex: .todo-list) but all the code is based around ids: (ex: #todo-list).
