Random Greeting Card Generator (Challenge)

# Introduction

In this challenge, we will create a Holiday Greeting Card using HTML, CSS, and JavaScript. The card will allow us to write and display personalized greetings for our loved ones and friends. To complete the challenge, we need to fill in the TODO section in the `index.js` file, and then use the Web Server service to run the project. Once completed, we can click "Write" to randomly display the pre-written greetings on the card.
