Your player is great, thank you! I found a syntax error that breaks some of the responsive CSS. This tiny edit -- adding a single semicolon to one line of CSS -- fixes the problem.

I'm using this package as a dependency, and I want Webpack to be able to [optimize it out automatically](https://webpack.js.org/configuration/optimization/#optimizationsideeffects) if it ends up being the case that I do not use it (or only use parts of it).

Skimming through the source code, I don't see any of the files running any code as the files are loaded, which should mean that the project qualifies as being side-effect free and can be optimized by Webpack.
