Great information, thanks for sharing. As a web designer, I find these trends very relatable and useful in general. One more thing that I would add, would be the use of neomorphism in design. More and more web development companies use it these days. For example, the other day I saw this company based in Singapore, and from their website you can see the usage of this trend. In general, I think that the community should share more these sorts of things, different insights that are helpful in the area of coding, design, and testing. Sharing is caring after all. I would like to hear more from you guys.
