To create a pop-up window in HTML, utilize the `<dialog>` tag, then employ JavaScript to control its visibility. First, include the `<dialog>` element in your HTML with an `id`, and place your content within. For instance: `<dialog id="myPopup">This is a pop-up!</dialog>`. Next, add JavaScript to open and close the dialog. Use `document.getElementById("myPopup").showModal();` to show the pop-up and `.close();` to close it. Remember, not all browsers may fully support `<dialog>`, so consider fallbacks or polyfills for wider compatibility.
