Clicking on list items triggers the displayContent function, which updates the page's header, content, and image based on the clicked item's data attributes.
Clicking the hamburger menu icon toggles the visibility of a list.
This function toggles a CSS class called before:w-full on an element to add or remove a red line.
This function updates the page's content based on the data attribute of the clicked list item.

An Intersection Observer is used to detect when certain elements with the class section become visible on the screen. When an element is 30% visible in the viewport, it is marked as "visible," allowing for animations or other effects.
