How to find elements by CSS selectors in Playwright?

The most popular way to parse HTML content in web scraping are CSS selectors which are the default way to locate elements in Playwright as well. To find elements using CSS selectors we can use page.locator() method. For example:

from playwright.sync_api import sync_playwright

with sync_playwright() as pw:
    browser = pw.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 1920, "height": 1080})
    page = context.new_page()
    page.goto("https://google.com/")

    h2_element = page.locator("h2.some-class")

⚠ It's possible that these commands will try to find elements before the page has fully loaded if it's a dynamic javascript page. For more see How to wait for page to load in Playwright?
