Tackled #1329 with [PurgeCSS](https://purgecss.com/). Being talking with @varuniyer about using [jekyll-uncss](https://github.com/episource/jekyll-uncss) to reduce css file sizes by ditching unused classes. This approach have 3 main problems: 1 - have some limitations as pointed [here](alshedivat/al-folio#1329 (comment)) 2 - last update to [jekyll-uncss](https://github.com/episource/jekyll-uncss) was about 3 years ago, so it might have a few issues 3 - [uncss](https://github.com/uncss/uncss) haven't seem a new release in a while, currently [lacking maintenance](uncss/uncss#459), and using some deprecated libraries as seem here: ``` npm install -g uncss npm WARN deprecated request-promise-native@1.0.9: request-promise-native has been deprecated because it extends the now deprecated request package, see request/request#3142 npm WARN deprecated har-validator@5.1.5: this library is no longer supported npm WARN deprecated w3c-hr-time@1.0.2: Use your platform's native performance.now() and performance.timeOrigin. npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details. npm WARN deprecated request@2.88.2: request has been deprecated, see request/request#3142 ``` I thought about giving PurgeCSS a go, since it has been more [actively maintaned](https://github.com/FullHuman/purgecss), but [jekyll-purgecss](https://github.com/mhanberg/jekyll-purgecss) haven't. For this, I needed to change to use some local libraries instead of getting them via CDN. The good news is that it is quite effective in reducing css file sizes.
