Styling elements

I really have no idea why my code doesn't work. Check my code, please.

const toggleList = document.querySelector('#taggleList'); const listDiv = document.querySelector('.listDiv'); const input = document.querySelector('input'); const p = document.querySelector('p.description'); const button = document.querySelector('button');

toggleList.addEventListener('click', () => { listDiv.style.display = 'none'; });

button.addEventListener('click', () => { p.innerHTML = input.value + ':'; });

p.title = 'List description';

Thank you!

The console expresses "app.js:7 Uncaught TypeError: Cannot read property 'addEventListener' of null"

const toggleList = document.querySelector('#taggleList');

^ in the first variable youre not correctly selecting the id of toggleList. In the video they use getElementById for this specific part.

const listDiv = document.querySelector('.listDiv')

^ Also, there isn't a class of listDiv in index.html
