Basic Navigation Links on Top for Multi-Page Apps

I was able to use your code and get multi-page working locally! Next challenge is on my Flask server, you have this code in your app.py:

@app.server.route(’/static/path:path’)
def static_file(path):
static_folder = os.path.join(os.getcwd(), ‘static’)
return send_from_directory(static_folder, path)

Where is this called and is the path:path suppose to be specified somewhere? thanks
