querySelector

Select with CSS selectors

querySelector() finds the first element matching a CSS selector. It's flexible and widely used.

const el = document.querySelector(".item");
const nested = document.querySelector("div > p.intro");
const byId = document.querySelector("#header");

Any valid CSS selector works. Returns null if no match.
