Is it possible to jump to HTML element by class instead of id?

Question

I know that you can jump to elements by id but is it possible to jump to elements by class?

Am I going to have to use javascript to add an id to the element with that class name?

It would be a pain to add ids manually every time, the class names will already be there.

*I could have worded my question a bit better. I meant to use class names that are already there as anchor tags to jump to. The html I'm working with has class names for a LOT of individual elements and no ids. I'm wanting to jump to those elements without having to add an id to each and every one.

Answer 1

window.scrollTo(0, document.querySelector(".className").offsetTop);
