Re: An idea
Funny story. A potential customer had some issue with a website - I said we'd look into it. It's a single page site, not a huge amount of content - maybe 3 or 4 screens high, text, no video, minimum graphics.
Total weight of the CSS, after I had de-minified it to investigate? 1.5MB. Of CSS.
The minification made this considerably worse because literally every single stylesheet the developers (I presume they were legion) needed had been assembled into about 4 or 5 god-almighty huges files, which were then minified This included a dozen or so google fonts CSS files, various toolkits and the like, most of which are boilerplate thats shared over millions of websites, and none of which will benefit from caching from Cloudflare, ISP, or local browser cache from other sites due to the the way they're packaged.
Performance during load was appalling, performance during rendering was appalling (it's matching every element in the HTML to tens of thousands of CSS rules). We walked away and said we couldn't help them.
