Thing is ignoring the separation of concerns does NOT result in faster to build, clearer, simpler, or "better for collaboration" code. It pisses away caching models, HTTP parallelism, the reduction of server load, and dozens of other things CSS handed us on a silver platter.

It is thus even for applications halfwitted crap like bootcrap and failwind provide NO BENEFITS. All the claims of how much "better" they are are propaganda driven lies. There are no benefits to them other than "wah wah, eye dunz wunna lurn teh CSS".

Well, unless your entire intent is to work as hard as possible, write two to ten times the markup needed, and to shit on why you'd even choose HTML and CSS in the first place.

EVEN for application building. People claiming otherwise need to learn HTML and CSS. Though that's common enough a problem with all the stuff people still throw JavaScript at that HTML and CSS have been able to do without JS for over a decade.

If anything is being taken advantage of, it's the marks who believe the BS nonsense fraudsters like Otto and Wathan peddle.
