As a disclaimer, this entire post is written purely from the perspective of a developer. I’m not a designer, I’ve never claimed to be, I never will claim to be, and any type of design that I do is usually based around principles and foundations and guidelines that I’ve read and followed elsewhere on the web.
With that said, there’s been interesting conversations around some of the more popular design types as of late – some that are already retired, some that are still around, and some that are still beginning to emerge.
This includes trends such as Skeumorphic Design, Flat Design, and Material Design. And the reason I bring them up is because, at some point or another, we’ve seen these take their place (or beginning to take place) within the context of WordPress themes.
