A navigation bar is undoubtedly a really important element considered while designing websites and web pages. In a website, it’s utilized in navigating around the site through specific links. However, on a single page, navigation bars are used to quickly navigate through sections or portions of the page. In this challenge, we shall build a navigation bar which tracks the portion of the page currently in view.
In this challenge, it is required to build out a simple navigation bar, content on the page with various HTML elements and implement the tracking feature on the navbar. Once a specific portion of a page comes in the viewport while scrolling, its corresponding title in the navbar should be highlighted. Here is what the final product should look like.
As always, feel free to complete this challenge using any tool, technique or framework. However, there is one single requirement, once a portion of the page is scrolled to, its corresponding navigation link on the navigation bar should be highlighted. This way each specified portion currently in the viewport can be readily seen in the navigation bar.
Goals for this challenge
At the end of this challenge, you should be able to:
- Implement scroll-spy on a page by tracking portions or elements in the page and highlighting the navbar.
- Understand DOM traversing and manipulation.
To quickly get this challenge off the ground, a base codepen has been provided containing HTML for the page structure, nav bar and content on the page.
Fork this base codepen as your starting point
