How often are reset stylesheets used by working professionals?

I’ve been reading about the pros and cons of css resets and would like to know how common they are among working web devs. Should I use them while learning? So far, I’ve done all my projects (currently on JS calculator) without them.

Back in the early wild wild west days of the Internet, different browsers have inconsistencies. The Reset or the Normalize CSS hoped to make everything start at a default baseline, if you will, so that the page will look the same on different browsers.

Nowadays, is it still needed? Debatable. Would it hurt your site? I don’t think so. Is it required? Not really, if you don’t care about cross-browser inconsistencies/rendering.

Plus besides, some CSS frameworks (like Bootstrap) already have built-in css normalize/resets.
