<p>Puppeteer provides users the ability to add their own query selectors to Puppeteer using <a href="/next/api/puppeteer.registercustomqueryhandler">Puppeteer.registerCustomQueryHandler</a>.

<p>CSS selectors follow the CSS spec of the browser being automated. We provide some basic type deduction for CSS selectors (such as <code>HTMLInputElement</code> for <code>input</code>), but any selector that contains no type information (such as <code>.class-name</code>) will need to be coerced manually using TypeScript's <code>as</code> coercion mechanism.</p>
