Nowadays we face a different sort of browser war; one where the browser is constantly tracking what we do as users. The greed of advertising companies is driving this, and I'm not a fan. I'm a big advocate of privacy, performance and user experience. These three things are at the core of everything I do.
I'm also a supporter of writing CSS using plain old CSS and not the latest utiility frameworks. Why? My personal experience is I can compose pure CSS much quicker than constantly having to remember what the utility framework's class might be to achieve the style I'm after.
Professionally I've been working with Vue.js for half a decade, and I don't like the idea of populating a bunch of utility classes onto HTML elements when I can just as easily create a class and keep the styling and presentation separate.
