[Solved] pop up window does not open when code added in java script


As pointed out, the problem was that the event handler was listening for any kind of click event in the window object. Instead I refactored the code and put the respective buttons in variables and added the addEventListener.

// contact-form opens upon clicking the "get a quote" Button

let quoteButton = document.getElementById('quote-button');

quoteButton.addEventListener('click', function() {
 let contactWrapper = document.getElementById('contact-wrapper');
  if (contactWrapper.style.display == 'none') {
    contactWrapper.style.display = 'flex';
  } else {
    (contactWrapper.style.display = 'none');
  }
});

//contact-form disapears when clicking "back" Button

let backbutton = document.getElementById('back-button');

backbutton.addEventListener('click', function() {
  let contactWrapper = document.getElementById('contact-wrapper');
    if (contactWrapper.style.display == 'flex') {
      contactWrapper.style.display = 'none';
    } 
});
