Quick Answer
Detect visibility: .is(":visible") returns true if the element is visible (has dimensions and is not display:none or hidden). .is(":hidden") is the inverse. For viewport visibility (whether on screen), use IntersectionObserver natively or a plugin - jQuery has no built-in viewport detection. .offset() and .height() let you calculate position relative to viewport manually.
