YouTube Video Explainer with JavaScript

Do you use YouTube videos on your site? Have you ever wanted to show a message that explains a particular part of the videos to your site visitors? This small script allows you to do that. You can customize it to show a notification box at a specific time. With this script, there is no need to insert text messages directly to the video which is impossible if the video is created by others. Not only for site visitors, you can also use it for another purpose. If you are in the process of learning something and using some YT videos as personal reference, use the script to give additional info to the important parts of the videos. The next time you watch the videos, the extra messages will enable you to grab the materials better.
