CSS CSS Foundations Advanced Selectors UI Element States Pseudo-Classes

What does "UI" mean when used in a sentence like, "UI Element States Pseudo-Classes"

Stuck on a definition. "UI" element states pseudo-classes target elements based on certain user interactive states". I can't seem to find it in the teacher's notes or the glossary of a book on writing HTML.

Thanks for your help

UI typically refers to user interface, which regards anything the user can see or interact with. Simplified, an element is just something on the page: a submit button, a link, etc. Not really something to get hung up on.

Hi Steven,

I believe it means "user interaction".

These element states describe a user-state of an input field (i.e. a targeted input or a non-targeted input, a checked box or radio button) when it's being actively or passively interacted with (i.e. when filling out a form).
