A scrollspy is a navigation section that stays up to date on where the user is scrolled. So if the user scrolls manually to a section, it will show that section on the navigation automatically.
Clicking on the section will also scroll the page to that section.
This scrollspy is based on the Bootstrap implementation.
These team portrait circles are grayscale until hover, and then they show the color and a tooltip with the team member s name and role.
The tooltips are based on Tippy and Popper.js, so they never go off the screen.
Simple, subtle, and effective
