Embedding every style directly into the style attribute is also readable, and as a side benefit it doesn't need a build step just to make your styles actually work.
I can now see exactly why OP made this post. If a client told me they don't want to use something akin to bootstrap or any other sane css library, and that instead I will need to ensure that every element has every manner of css states expressed as a faux class, I wouldn't even stop to make a coffee before telling them how far they can jump.
This sounds perfect for front end “developers" who struggle even with css, and want any reason possible to pad out their billable/working hours doing nothing productive.
Oh what's that, you want to change the style of standard button everywhere in the codebase?
No of course we can't just update a single css file you silly goose.
I feel like half the bad problems in web development are because JavaScript developers saw that j2ee guys had ant and whatnot, and said "hey what if we started inventing reasons to have a build step"?
> button class="button"
The thing is, that is more readable for a sane code base. If I can glance and know it's using the correct standard button class, it means I don't need to memorise the fucking pixel sizes and states of button paddings.
I get it alright. It's a solution looking for a problem that doesn't exist, and instead found a crowd of "developers" looking for anything shiny to pad their resume and keep themselves looking busy.
