🧭 Building a CSS-Only Course Navigator with Modern Techniques

I recently came across this awesome article navigation component by Jhey Tompkins on CodePen. It helped me solve a UX issue I was facing in a project, so I adapted it for an online course layout — what I like to call a “course navigator.”

In this article, I’ll walk you through how I built it, what it does, and how we can leverage modern CSS to create a powerful, interactive navigation component — all without JavaScript (well, almost).

🎯 What the Course Navigator Does

This component is designed for online learning platforms. It:

– Links to all course lessons
– Smoothly scrolls to lesson sections via anchor links
– Displays how much of the current lesson has been read
– Supports light/dark mode toggling
– Stays fixed at the bottom of the screen and collapses on scroll

And yes — it’s built entirely with HTML and CSS using cutting-edge features currently supported in Chrome.

🧱 The HTML Structure

The core of this component is a

element fixed to the bottom of the page. Inside it, a

acts as the toggle. The course content is wrapped in an Section A
  • Section B
  • Section C
