I've heard all this before. I am extremely sceptical and tbh I wouldn't want to build a site this way at all.
It goes against what CSS was supposed to do and generally the results are IMO hard to work with because you have the overhead of having to learn how the framework works rather than just using the fundamental principles of what you are working with. Also the markup is horrendous to read.
With modern CSS you are given so much control. Your style-sheets aren't complicated anyway.
I agree. I like CSS, and I don't like anything the frameworks offer, they're just the worst of all possible worlds: a LOT of CSS (it's not just the "custom CSS" that counts, from the perspective of the browser even off-the-shelf Bootstrap is 100% custom), with no aesthetic pleasure to show for it.
But that's for my own projects I work on as a single dev, in a team I might not mind as much. For something corporate, unless it's a corporation I can really get behind, I will not care at all, because I know it'll be thrown away soon. Let's make it bland then, I don't mind. But for my own things, it's not even a consideration.. I don't even start with a reset stylesheet, I start with a blank file, and I enjoy thinking up the overall structure just as much as I enjoy tweaking values here and there, and I still like things I made over 10 years ago. Care for the little things always ends up showing, somehow.
