i cant figerout why my scrollspy not working 
Youāve got a number of problems here. First, youāre importing both Bootstrap 3.7 and 4-alpha in your CSS and JavaScript sections. Just pick one version as there will likely be conflicting code (I suggest sticking with 4-alpha). Second, when you define data-target in the <body> tag, Bootstrap is expecting a reference to an element with the nav class. #navnav is missing the nav class. Try fixing both of those problems and see if it helps. Hereās the documentation for 4-alpha:
Also, while itās not likely messing up ScrollSpy, you should take all of the style definitions in your HTML and move them to your CSS. Itās really, really hard to read your code as is. Otherwise, good job so far. Your portfolio is coming together.

Your html for navigation bar differs from how itās supposed to be written. Bootstrap highlights navigation elements by adding āactiveā class to āliā tag:
