To close a popup form in JavaScript, you typically need to alter the CSS `display` property of the popup element to `none`. First, ensure your popup has an `id` for easy targeting. Then, use a JavaScript function that selects this element by its `id` and sets its style display property to `none`. For example: `document.getElementById('popupFormId').style.display = 'none';`. This code effectively hides the popup from view, effectively 'closing' it. It's a straightforward and widely used method for controlling the visibility of webpage elements.
