The problem Loader and Navbar solves

Previously on the website, we didn't have a preloader so I've created Pre-loader to entertain visitors while the server keeps processing and to make this website more interactive. I created it using HTML, CSS and Javascript the pre-loader is responsive so, It can run on all available devices. Then I made a navbar for the same website and I was created with the same technology I used in creating a pre-loader this was to be responsive and can run smoothly on all devices.

Challenges I ran into

The biggest challenge was to work on someone else written code then somehow I managed to familiarize myself with everything then when I started working on the task It was very difficult for me as I have never contributed to any repository before so, I educated myself on the git commands then I learned about new styling commands for CSS. In building the navbar, the biggest challenge was to make it responsive so I also looked and read a lot about how to create one then after all this hard work I finally managed to make a responsive navbar.
