What I learned

I learned how to create a modal and dim the entire page background. The trick is not to use opacity but to use rgba for background and make sure that the modal is positioned absolute and the dimmed background is a div which is positioned fixed. This div should be not be a child of any other element.

I also learned how to use the scrollIntoView method which scrolls to the element you want. This is usefel when you have a long webpage and click events across the page pop up the modal. Instead of the user scrolling to find the modal, they will automatically be taken to it. See below:

function scrollToModal(modal) {
  modal.scrollIntoView();
}
