Hi @vatz88 I made quite a few changes in this PR but don't worry you don't have to look at the code, I'll list down the things I've changed below.

• Moved SCSS rules into separate files and removed rules no longer in use. In the past you were hesitant to use custom CSS because it might not have cross browser support, so I've moved as much as I could to bootstrap and now there's barely any custom CSS (I'm surprised too).
• Moved JS functions into separate files, removed redundant and deprecated code. You were concerned with how I was storing a bunch of data and functions in the window object, I googled about that and looks like you were right, while requiring a package in nodejs as long as it's in the same directory it always gives the same instance. However I think Bootstrap 4 requires jQuery to be a window object because of how it access' it, one of the packages we use requires BS4 for now, however I might be able to resolve this once they release a stable version with BS5 support.
• I've added separate last update fields for vellore and chennai for obvious reasons and also moved the last updated semester to a more viewable location. This value changes when the semester is changed.
• I've changed the ascending and descending arrows to use FontAwesome icons instead making it more UI friendly. Also, I changed ascending to an up-arrow and descending to a down-arrow (it was reversed), after someone mentioned it in the past I looked around and found people saying the pointed part is the smaller part. If you want me to change it back let me know.
• And finally the x-axis padding in the timetable and course list, you wanted them to be full width but it didn't look very good on larger devices, so I've added a breakpoint to use full width on smaller devices only (personally I think it looks better if smaller devices had a small amount padding as well but this works too).

If you have any suggestions please let me know, I won't be merging this PR immediately (Edit: It looks like I don't have permission to merge my own PRs). There's still a tiny amount of cleaning left. I'll merge it after I resolve #169. I did this cleanup first so that everything would be more organised for the major changes I'll have to do to support different timetables.

This PR closes most of #193.
