Navbar with index and progressbar
Free to clone:
Navigation bar with site progress & index including a little link menu.
On scroll the navbar hides and the progress bar shows the site scroll progress with an indicator going trough each chapters / section. Made simply with anchor point and one scroll interaction. Based on finsweet client first structure (more or less).
If section will be different in height, just adjust the page interaction and set some individual keypoints for each section.
Happy cloning.
