From a web development perspective, UX is a way of refining a website to be as engaging and pleasurable to visit as possible.
Micro UX takes a look at the tiny things on a website that can add up to make all the difference. It's especially vital for design- and concept-heavy websites trying to push an aesthetic with branding in mind. The best thing about micro UX is that once the design decisions have been made, they're usually extremely easy to code and incorporate in the website.
