Document.createElement('div') With A Class

I can use createElement() to create an HTML element via JavaScript like this: let div = document.createElement('div'); But how can I add a CSS class to my newly created div? I tri

Solution 1:

Do div.classList.add

let div = document.createElement('div');
div.classList.add('test');
let text = document.createTextNode('Test');
div.appendChild(text);
document.body.appendChild(div)

.test {
  color: green;
}

You can also do by className

let div = document.createElement('div');
div.className = 'test';
let text = document.createTextNode('Test');
div.appendChild(text);
document.body.appendChild(div)

.test {
  color: red;
}

Solution 2:

You can use Element.classList.add

let div = document.createElement('div');
div.classList.add("myDiv")
