Responsive notification page using html,css,bootstrap and javascript

Hi everyone, this is my Solution to the notification-page challenge. in this project i tested my knowledge in javascript as i am still learning.I would love it if my codes can be checked for review especially the click functions, also i would appreciate suggestions on other projects to hop on , i'm interested in explanding and testing my knowledge in css and javascript. I am not aware if commenting codes to be deployed is a bad practice but i commented some codes which are supposed to serve as reference for an alternative that also works. I will be expecting corrections and suggestions to my solution.Thank you PS:this is my first challenge on frontendmentors
