Web designers are usually just that. Designers. Which means their focus is on what looks pretty. And prettiness is their north star.
It is not unusual to find a web designer’s website —whether built for a client or their own agency— is several megabytes in size to download.
This is because designers usually don’t think beyond the appearance.

Me? I’m more of a website optimiser. Good design is as much about performance and “how it works,” as it is about “how it looks.”
Carousels, animations, and things that move around, are popular brushes many designers paint with.
