# querySelector method

Element querySelector (String selectors)

Finds the first descendant element of this document that matches the specified group of selectors.

Unless your webpage contains multiple documents, the top-level querySelector method behaves the same as this method, so you should use it instead to save typing a few characters.

`selectors` should be a string using CSS selector syntax.

    var element1 = document.querySelector('.className');
    var element2 = document.querySelector('#id');

For details about CSS selector syntax, see the CSS selector specification.
