How to use

What advanced CSS selector patterns are supported?

It supports attribute selectors ([type="text"]), combinators (>, +, ~), and structural pseudo-classes like :nth-child and :first-of-type.

Can I use this to verify scraping selectors?

Yes. It is ideal for testing CSS query selectors before embedding them into Puppeteer, Playwright, or Cheerio scraping scripts.

Is my HTML code snippet sent across the internet?

No. The tester relies on your browser’s native querySelectorAll API client-side, keeping all code samples completely confidential.
