You are about to write your first jQuery code. The goal of this exercise is to re-use what you have learned throughout the CSS module about selectors, to dynamically manipulate the web page.

We say that we manipulate the Document Object Model (DOM), which is the in-memory representation of the HTML built by the browser. It is a tree (root node, with children, and grand-children, etc.), and you can:

• Traverse it to read a specific node
• Remove some nodes
• Add some nodes

Open the application.js file, you will find a list of challenges to complete.

You will see that all results are failing. Solve them from top to bottom, and hit F5 (Refresh) each time you want to check if you've solved an exercise.
