Like this. How does it work if your CSS file is dynamically generated from an SCSS file?
Cool idea but way too expensive.
Daily Scheduled CSS optimisations? Who's updating their CSS daily apart from css-tricks.com?
Looks good, but pricing is crazy - way too expensive.
This is absurd as a subscription-based product. There are dozens of CLI tools that do exactly this for free, such as https://github.com/FullHuman/pur... And because they're CLI based you can include it in your task runner so that it only runs when new iterations of a project are built. Compiled CSS shouldn't change outside of new builds, certainly not enough to warrant paying for "daily scheduled optimizations."
