Is JavaScript an alternative to the html

Question

If yes then r we required to learn CSS with JavaScript to conter HTML with CSS or JavaScript alone I sufficient

Answer 1

It’s not an alternative. You could write a whole web page with javascript, but the javascript still has to output html code to make the page. Either way, css isn’t a requirement, just a good thing.

Answer 2

//CSS is only for styling web documents created on html, where if you want to handle html events you need to learn javascript, like click event, alerts etc
