I'm a crusty old HTML and CSS person. The problem is that most of the skills are in the marketing department - not engineering.
I've noticed lately a huge "React-ification" in the past few years where the UI on apps are both getting overly designed, but also more confusing and worse. Bigger buttons, bigger text, overuse of whitespace, bad pagination and breadcrumbs, etc.
There are a lot of best practices that were "solved" a decade ago that now seem to be getting lost. And the explanation that I have is that React and Figma have made it so easy to spin up a web app without any prior experience or reliance on prior works. "Enough rope to hang themselves" as the saying goes.
I worked with an engineering team that was struggling with their UI. The buttons were all the wrong sizes, colors weren't consistent, placement wasn't consistent, etc. I asked them if they were using a CSS framework at all and the response was "we are using React, we don't need one".
