# Introduction In this challenge, you are tasked with implementing a Video Bullet Comments feature. Bullet Comments refers to comments that appear directly on the video, which can appear in the form of scrolling, staying, or even more special effects. This feature allows viewers to interact with the video in real-time, making the viewing experience more engaging and fun. You will need to complete the code in the `js/index.js` file to control the display color and movement of the Bullet Comments, as well as handle the event of sending a new Bullet Comments when the user clicks the send button.
