Responsive Fylo Dark theme Landing Page

I struggled a bit with adding the waveform, but the background image property came through for me. This was a really rewarding experience. I initially deployed using github pages but the waveform was not loaded by github so I used netlify. I tried installing bootstrap globally to write custom sass files. I am still not sure of what went wrong with the setup(the css bootstrap import section) but I ended up loading the bootstrap CDN and still writing sass separately. Therefore, I used features like bootstrap containers and grids in addition to my custom styles. Any feedback is welcome.
