How to center a textarea using CSS?

Question

Forgive me for asking such a simple question, I'm new to both HTML and CSS. Is there an easy way to center a textarea? I figured I'd just try using

textarea{
    margin-left: auto;
    margin-right: auto;
}

but it (obviously?) didn't work.

This should do the trick. It works for me here in 2020:

textarea {
    margin: auto;
    display: block;
}
