dsonesuk 906 Posted October 25 Report Share Posted October 25 (edited) Wrap in quotes 'p, div', then use for loop with makeBold.length to loop through collection from querySelectorAll(); to apply required style. Edited October 25 by dsonesuk 1 Quote Link to post Share on other sites
vmars316 5 Posted October 25 Author Report Share Posted October 25 Thanks dsonesuk ; Like this: Quote <script> //Get the button element var btn = document.getElementById('button'); //Get paragraph element var makeBold = document.querySelectorAll('p , div'); //Define an click event listener on button btn.addEventListener('click', function() { for (i = 0; i < makeBold.length; i++) { makeBold[i].style.fontWeight = '700'; } }); </script> Thanks !
