To get ready, you can review the completed recipe by running harp server in the chapter7/complete folder and navigating to localhost:9000/recipe07-03. To see the simple effect we can achieve with this plugin, click on the button that reads Toggle Navbar Color.
After previewing the result we are trying to achieve, navigate to the chapter7/start folder and open the _js.ejs, _nav.ejs, _recipe-07-03-js.ejs files in the app/partial folder. Also, one level up, in the root of the app folder, open the file titled recipe07-03.ejs.
