To create an expandable navigation menu using HTML and CSS, you can start by creating a list of links within a `<ul>` element in your HTML code. Then, use CSS to style the menu by setting the `<ul>` element to `display: none;` to hide it initially. Next, use CSS to target a specific element, like a hamburger icon or a button, and add a click event listener to toggle the visibility of the `<ul>` element by changing its display property to `block` or `flex`. This way, when the user clicks on the designated element, the navigation menu will expand and collapse. **
