We want to remove a div with the ID
const elem = document.getElementById('custom_id'); elem.remove();
And yes, that's how simple it is!
But perhaps you only want to hide it for a brief moment? We can also modify the script to make the element invisible for a while.
const hidden = document.getElementById('hidden_id'); hidden.style.display = 'none';
And that will make your element hidden until you make it visible again.
It can be made visible by swapping the display to block/flex/inline.
const hidden = document.getElementById('hidden_id'); hidden.style.display = 'block';
