Steps to showcase a form on a webpage using a button

My webpage features an HTML table with a table navigation bar that allows users to add items or inventory. However, when the "add item" button is clicked, a form appears below the table instead of on top of it. I want the form to display itself right on top of the table without displacing it. I am open to suggestions and would like to use JavaScript for this task. Here's my code:

HTML Code:

<!DOCTYPE html>
...
</html>

CSS Code:

html, body {
    height: 100vh;
}
...

There are various methods to achieve this functionality. What you're referring to is a traditional "Modal" feature.

  1. The simplest solution would be (as mentioned in the comment): utilize bootstrap modal.

  2. You can hide the form using display: none; and reveal it with display: inherit; when necessary. Add a class to your form using document.getElementById("formId").classList.add("open"); then define the style in your CSS:

    .open { display: inherit; position: fixed; top: 50%; left: 50%; transform: translatX(-50%) translateY(-50%); z-index: 1; }

  3. A more complex option would be to create a custom modal component that renders your form as a nested component.

If you provide a Codepen or Codesandbox link, it would make it simpler for us to assist you further.
