Introduction

In this lab, we will explore the world of CSS and its capabilities by creating a list with sticky headings for each section. The aim is to showcase how to use the position: sticky property to create a user-friendly interface that enhances the user experience. Through this lab, you will learn how to use CSS to create visually appealing and functional web pages.

List With Sticky Section Headings

index.html and style.css have already been provided in the VM.

To create a list with sticky headings for each section, follow these steps:

1. Allow the list container (<dl>) to overflow vertically by using overflow-y: auto.
2. Stick the headings (<dt>) to the top of the container by setting their position to sticky and applying top: 0.
3. Use the following HTML and CSS code:

HTML:

<div class="container">
  <dl class="sticky-stack">
