-Selectors query elements on the web page for interactions, like [`method: Page.click`], and to obtain `ElementHandle` through [`method: Page.$`]. Built-in selectors auto-pierce [shadow DOM](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM).
+Selectors are strings that point to the elements in the page. They are used to perform actions on those
+elements by means of methods such as [`method: Page.click`], [`method: Page.fill`] and alike. All those
+methods accept [`param: selector`] as their first argument.

-## Working with selectors
+## Basic text selectors
 
-Selector describes an element in the page. It can be used to obtain `ElementHandle` (see [`method: Page.$`] for example) or shortcut element operations to avoid intermediate handle (see [`method: Page.click`] for example).
-
-Selector has the following format: `engine=body [>> engine=body]*`. Here `engine` is one of the supported [selector engines](./selectors.md) (e.g. `css` or `xpath`), and `body` is a selector body in the format of the particular engine. When multiple `engine=body` clauses are present (separated by `>>`), next one is queried relative to the previous one's result.
-
-Playwright supports various selector engines:
-  * [Text] selectors, for example `text="Log in"`
-  * [CSS] selectors, including the following extensions:
-    - [Shadow piercing](#shadow-piercing) by default and [`:light`](#css-extension-light) pseudo-class
-    - [`:visible`](#css-extension-visible) pseudo-class
-    - [`:text`](#css-extension-text) pseudo-class
-    - [`:has`](#css-extension-has) and [`:is`](#css-extension-is) pseudo-classes
-    - [Position selectors](#css-extension-position), for example `button:right-of(article)`
-  * [XPath] selectors, for example `xpath=//html/body/div`
-  * [id selectors][id], for example `id=sign-in`
-  * [Custom selector engines](./extensibility.md)
-
-For convenience, selectors in the wrong format are heuristically converted to the right format:
-- selector starting with `//` or `..` is assumed to be `xpath=selector`;
-- selector starting and ending with a quote (either `"` or `'`) is assumed to be `text=selector`;
-- otherwise selector is assumed to be `css=selector`.
+Text selectors locate elements that contain text nodes with the passed text.
 
 ```js
-// queries 'div' css selector
-const handle = await page.$('css=div');
-
-// queries '//html/body/div' xpath selector
-const handle = await page.$('xpath=//html/body/div');
-
-// queries '"foo"' text selector
-const handle = await page.$('text="foo"');
-
-// queries 'span' css selector inside the result of '//html/body/div' xpath selector
-const handle = await page.$('xpath=//html/body/div >> css=span');
-
-// converted to 'css=div'

+page.click("text=Log in")
 ```
 
-## Syntax
-Selectors are defined by selector engine name and selector body, `engine=body`.
+By default, the match is case-insensitive, it ignores leading/trailing whitespace and searches for
+a substring. This means `text= Login` matches `<button>Button loGIN (click me)</button>`.
 
-* `engine` refers to one of the supported engines
-  * Built-in selector engines: [css], [text], [xpath] and [id selectors][id]
-  * Learn more about [custom selector engines](./extensibility.md)
-* `body` refers to the query string for the respective engine
-  * For `text`, body is the text content
-  * For `css`, body is a [css selector](https://developer.mozilla.org/en/docs/Web/CSS/CSS_Selectors)
+Text body can be escaped with single or double quotes for precise matching, insisting on exact match,
+including specified whitespace and case. This means `text="Login "` will only match
+`<button>Login </button>` with exactly one space after "Login". Quoted text follows the usual escaping
+rules, e.g. use `\"` to escape double quote in a double-quoted string: `text="foo\"bar"`.
 
-Body format is assumed to ignore leading and trailing white spaces, so that extra whitespace can be added for readability.
+Text body can also be a JavaScript-like regex wrapped in `/` symbols. This means `text=/^\\s*Login$/i`
+will match `<button> loGIN</button>` with any number of spaces before "Login" and no spaces after.
 
-### Short-forms
-For convenience, common selectors have short-forms:
-- Selector starting with `//` or `..` is assumed to be `xpath=selector`
-  - Example: `'//html'` is converted to `'xpath=//html'`.
-- Selector starting and ending with a quote (either `"` or `'`) is assumed to be `text=selector`
-  - Example: `'"foo"'` is converted to `'text="foo"'`.
-- Otherwise, selector is assumed to be `css=selector`
-  - Example: `'div'` is converted to `'css=div'`.
+Input elements of the type `button` and `submit` are rendered with their value as text, and text
+engine finds them. For example, `text=Login` matches `<input type=button value="Login">`.
+
+Selector string starting and ending with a quote (either `"` or `'`) is assumed to be a text selector.
+For example, Playwright converts `'"Login"'` to `'text="Login"'` internally.
+
+## Basic CSS selectors
+
+Playwright augments standard CSS selectors in two ways:
+* `css` engine pierces open shadow DOM by default.
+* Playwright adds a few custom pseudo-classes like `:visible`.
+
+```js
+await page.click('button');
+```
+
+```python async
+await page.click("button")
+```
+
+```python sync
+page.click("button")
+```
+
+## Selecting visible elements
+
+The `:visible` pseudo-class in CSS selectors matches the elements that are
+[visible](./actionability.md#visible). For example, `input` matches all the inputs on the page, while
+`input:visible` matches only visible inputs. This is useful to distinguish elements that are very
+similar but differ in visibility.
+
+:::note
+It's usually better to follow the [best practices](#best-practices) and find a more reliable way to
+uniquely identify the element.
+:::
+
+Consider a page with two buttons, first invisible and second visible.
+
+```html
+<button style='display: none'>Invisible</button>
+<button>Visible</button>
+```
+
+* This will find the first button, because it is the first one in DOM order. Then it will wait for the button to become visible before clicking, or timeout while waiting:
+
+  ```js
+  await page.click('button');
+  ```
+
+  ```python async
+  await page.click("button")
+  ```
+
+  ```python sync
+  page.click("button")
+  ```
+
+* This will find a second button, because it is visible, and then click it.
+
+  ```js
+  await page.click('button:visible');
+  ```
+  ```python async
+  await page.click("button:visible")
+  ```
+  ```python sync
+  page.click("button:visible")
+  ```
+
+Use `:visible` with caution, because it has two major drawbacks:
+* When elements change their visibility dynamically, `:visible` will give unpredictable results based on the timing.
+* `:visible` forces a layout and may lead to querying being slow, especially when used with `page.waitForSelector(selector[, options])` method.
+
+## Selecting elements that contain other elements
+
+The `:has()` pseudo-class is an [experimental CSS pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:has). It returns an element if any of the selectors passed as parameters
+relative to the :scope of the given element match at least one element.
+
+Following snippet returns text content of an `<article>` element that has a `<div class=promo>` inside.
+
+```js
+await page.textContent('article:has(div.promo)');
+```
+
+```python async
+await page.textContent("article:has(div.promo)")
+```
+
+```python sync
+page.textContent("article:has(div.promo)")
+```
+
+## Selecting elements matching one of the conditions
+
+The `:is()` pseudo-class is an [experimental CSS pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:is).
+It is a function that takes a selector list as its argument, and selects any element that
+can be selected by one of the selectors in that list. This is useful for writing large
+selectors in a more compact form.
+
+```js
+// Clicks a <button> that has either a "Log in" or "Sign in" text.
+await page.click('button:is(:text("Log in"), :text("Sign in"))');
+```
+
+```python async
+# Clicks a <button> that has either a "Log in" or "Sign in" text.
+await page.click('button:is(:text("Log in"), :text("Sign in"))')
+```
+
+```python sync
+# Clicks a <button> that has either a "Log in" or "Sign in" text.
+page.click('button:is(:text("Log in"), :text("Sign in"))')
+```
+
+## Selecting elements by text
+
+The `:text` pseudo-class matches elements that have a text node child with specific text.
+It is similar to the [text] engine, but can be used in combination with other `css` selector extensions.
+There are a few variations that support different arguments:
+
+* `:text("substring")` - Matches when element's text contains "substring" somewhere. Matching is case-insensitive. Matching also normalizes whitespace, for example it turns multiple spaces into one, trusn line breaks into spaces and ignores leading and trailing whitespace.
+* `:text-is("string")` - Matches when element's text equals the "string". Matching is case-insensitive and normalizes whitespace.
+* `button:text("Sign in")` - Text selector may be combined with regular CSS.
+* `:text-matches("[+-]?\\d+")` - Matches text against a regular expression. Note that special characters like back-slash `\`, quotes `"`, square brackets `[]` and more should be escaped. Learn more about [regular expressions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp).
+* `:text-matches("value", "i")` - Matches text against a regular expression with specified flags.
+
+Click a button with text "Sign in":
+
+```js
+await page.click('button:text("Sign in")');
+```
+
+```python async
+await page.click('button:text("Sign in")')
+```
+
+```python sync
+page.click('button:text("Sign in")')
+```
+
+## Selecting elements in Shadow DOM
+
+Our `css` and `text` engines pierce the [Shadow DOM](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM) by default:
+- First it searches for the elements in the light DOM in the iteration order, and
+- Then it searches recursively inside open shadow roots in the iteration order.
+
+In particular, in `css` engines, any [Descendant combinator](https://developer.mozilla.org/en-US/docs/Web/CSS/Descendant_combinator)
+or [Child combinator](https://developer.mozilla.org/en-US/docs/Web/CSS/Child_combinator) pierces an
+arbitrary number of open shadow roots, including the implicit descendant combinator at the start of the
+selector. It does not search inside closed shadow roots or iframes.
+
+If you'd like to opt-out of this behavior, you can use `:light` CSS extension or `text:light` selector engine. They do not pierce shadow roots.
+
+```js
+await page.click(':light(.article > .header)');
+```
+
+```python async
+await page.click(":light(.article > .header)")
+```
+
+```python sync
+page.click(":light(.article > .header)")
+```
+
+More advanced Shadow DOM use cases:
+
+```html
+<article>
+  <div>In the light dom</div>
+  <div slot='myslot'>In the light dom, but goes into the shadow slot</div>
+  #shadow-root
+    <div class='in-the-shadow'>
+      <span class='content'>
+        In the shadow dom
+        #shadow-root
+          <li id='target'>Deep in the shadow</li>
+      </span>
+    </div>
+    <slot name='myslot'></slot>
+</article>
+```
+
+- Both `"css=article div"` and `"css:light=article div"` match the first `<div>In the light dom</div>`.
+- Both `"css=article > div"` and `"css:light=article > div"` match two `div` elements that are direct children of the `article`.
+- `"css=article .in-the-shadow"` matches the `<div class='in-the-shadow'>`, piercing the shadow root, while `"css:light=article .in-the-shadow"` does not match anything.
+- `"css:light=article div > span"` does not match anything, because both light-dom `div` elements do not contain a `span`.
+- `"css=article div > span"` matches the `<span class='content'>`, piercing the shadow root.
+- `"css=article > .in-the-shadow"` does not match anything, because `<div class='in-the-shadow'>` is not a direct child of `article`
+- `"css:light=article > .in-the-shadow"` does not match anything.
+- `"css=article li#target"` matches the `<li id='target'>Deep in the shadow</li>`, piercing two shadow roots.
+
+## Selecting elements based on layout
+
+Playwright can select elements based on the page layout. These can be combined with regular CSS for
+better results, for example `input:right-of(:text("Password"))` matches an input field that is to the
+right of text "Password".
+
+:::note
+Layout selectors depend on the page layout and may produce unexpected results. For example, a different
+element could be matched when layout changes by one pixel.
+:::
+
+Layout selectors use [bounding client rect](https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect)
+to compute distance and relative position of the elements.
+* `:right-of(inner > selector)` - Matches elements that are to the right of any element matching the inner selector.
+* `:left-of(inner > selector)` - Matches elements that are to the left of any element matching the inner selector.
+* `:above(inner > selector)` - Matches elements that are above any of the elements matching the inner selector.
+* `:below(inner > selector)` - Matches elements that are below any of the elements matching the inner selector.
+* `:near(inner > selector)` - Matches elements that are near (within 50 CSS pixels) any of the elements matching the inner selector.
+
+```js
+// Fill an input to the right of "Username".
+await page.fill('input:right-of(:text("Username"))');
+
+// Click a button near the promo card.
+await page.click('button:near(.promo-card)');
+```
+
+```python async
+# Fill an input to the right of "Username".
+await page.fill('input:right-of(:text("Username"))')
+
+# Click a button near the promo card.
+await page.click('button:near(.promo-card)')
+```
+
+```python sync
+# Fill an input to the right of "Username".
+page.fill('input:right-of(:text("Username"))')
+
+# Click a button near the promo card.
+page.click('button:near(.promo-card)')
+```
+
+## XPpath selectors
+
+XPath engine is equivalent to [`Document.evaluate`](https://developer.mozilla.org/en/docs/Web/API/Document/evaluate).
+Example: `xpath=//html/body`.
+
+Malformed selector starting with `//` or `..` is assumed to be an xpath selector. For example, Playwright
+converts `'//html/body'` to `'xpath=//html/body'`.
+
+:::note
+`xpath` does not pierce shadow roots
+:::
+
+## id, data-testid, data-test-id, data-test selectors
+
+Attribute engines are selecting based on the corresponding attribute value. For example: `data-test-id=foo` is equivalent to `css=[data-test-id="foo"]`, and `id:light=foo` is equivalent to `css:light=[id="foo"]`.
+
+## Chaining selectors
 
-### Chaining selectors
 Selectors defined as `engine=body` or in short-form can be combined with the `>>` token, e.g. `selector1 >> selector2 >> selectors3`. When selectors are chained, next one is queried relative to the previous one's result.
 
 For example,
@@ -156,11 +306,13 @@ document
 If a selector needs to include `>>` in the body, it should be escaped inside a string to not be confused with chaining separator, e.g. `text="some >> text"`.
 
 ### Intermediate matches
+
 By default, chained selectors resolve to an element queried by the last selector. A selector can be prefixed with `*` to capture elements that are queried by an intermediate selector.
 
 For example, `css=article >> text=Hello` captures the element with the text `Hello`, and `*css=article >> text=Hello` (note the `*`) captures the `article` element that contains some element with the text `Hello`.
 
 ## Best practices
+
 The choice of selectors determines the resiliency of automation scripts. To reduce the maintenance burden, we recommend prioritizing user-facing attributes and explicit contracts.

-### Shadow piercing
-
-`css:light` engine is equivalent to [`Document.querySelector`](https://developer.mozilla.org/en/docs/Web/API/Document/querySelector) and behaves according to the CSS spec. However, it does not pierce shadow roots, which may be inconvenient when working with [Shadow DOM and Web Components](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM). For that reason, `css` engine pierces shadow roots. More specifically, any [Descendant combinator](https://developer.mozilla.org/en-US/docs/Web/CSS/Descendant_combinator) or [Child combinator](https://developer.mozilla.org/en-US/docs/Web/CSS/Child_combinator) pierces an arbitrary number of open shadow roots, including the implicit descendant combinator at the start of the selector.
-
-`css` engine first searches for elements in the light dom in the iteration order, and then recursively inside open shadow roots in the iteration order. It does not search inside closed shadow roots or iframes.
-
-```html
-<article>
-  <div>In the light dom</div>
-  <div slot='myslot'>In the light dom, but goes into the shadow slot</div>
-  <open mode shadow root>
-    <div class='in-the-shadow'>
-      <span class='content'>
-        In the shadow dom
-        <open mode shadow root>
-          <li id='target'>Deep in the shadow</li>

-      </span>
-    </div>
-    <slot name='myslot'></slot>
-  </open mode shadow root>
-</article>
-```
-
-Note that `<open mode shadow root>` is not an html element, but rather a shadow root created with `element.attachShadow({mode: 'open'})`.
-
-- Both `"css=article div"` and `"css:light=article div"` match the first `<div>In the light dom</div>`.
-- Both `"css=article > div"` and `"css:light=article > div"` match two `div` elements that are direct children of the `article`.
-- `"css=article .in-the-shadow"` matches the `<div class='in-the-shadow'>`, piercing the shadow root, while `"css:light=article .in-the-shadow"` does not match anything.

-### CSS extension: light
-
-`css` engine [pierces shadow](#shadow-piercing) by default. It is possible to disable this behavior by wrapping a selector in `:light` pseudo-class: `:light(section > button.class)` matches in light DOM only.
-
-```js
-await page.click(':light(.article > .header)');
-```
-
-```python async
-await page.click(":light(.article > .header)")
-```
-
-```python sync
-page.click(":light(.article > .header)")
-```
-
-### CSS extension: position
-
-Playwright provides position selectors based on the page layout. These can be combined with regular CSS for better results, for example `input:right-of(:text("Password"))` matches an input field that is to the right of text "Password".
-
-Note that position selectors depend on the page layout and may produce unexpected results. For example, a different element could be matched when layout changes by one pixel.
-
-Position selectors use [bounding client rect](https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect) to compute distance and relative position of the elements.
-* `:right-of(inner > selector)` - Matches elements that are to the right of any element matching the inner selector.
-* `:left-of(inner > selector)` - Matches elements that are to the left of any element matching the inner selector.
-* `:above(inner > selector)` - Matches elements that are above any of the elements matching the inner selector.
-* `:below(inner > selector)` - Matches elements that are below any of the elements matching the inner selector.
-* `:near(inner > selector)` - Matches elements that are near (within 50 CSS pixels) any of the elements matching the inner selector.
-
-```js
-// Fill an input to the right of "Username".
-await page.fill('input:right-of(:text("Username"))');
-
-// Click a button near the promo card.
-await page.click('button:near(.promo-card)');
-```
-
-```python async
-# Fill an input to the right of "Username".
-await page.fill('input:right-of(:text("Username"))')
-
-# Click a button near the promo card.
-await page.click('button:near(.promo-card)')
-```
-
-```python sync
-# Fill an input to the right of "Username".
-page.fill('input:right-of(:text("Username"))')
-
-# Click a button near the promo card.
-page.click('button:near(.promo-card)')
-```

-## Xpath selector engine
-
-XPath engine is equivalent to [`Document.evaluate`](https://developer.mozilla.org/en/docs/Web/API/Document/evaluate). Example: `xpath=//html/body`.
-
-Malformed selector starting with `//` or `..` is assumed to be an xpath selector. For example, Playwright converts `'//html/body'` to `'xpath=//html/body'`.
-
-Note that `xpath` does not pierce shadow roots.
-
-## Text selector engine
-
-Text engine finds an element that contains a text node with the passed text. For example, `page.click('text=Login')` clicks on a login button, and `page.waitForSelector('"lazy loaded text")` waits for the `"lazy loaded text"` to appear in the page.
-
-- By default, the match is case-insensitive, ignores leading/trailing whitespace and searches for a substring. This means `text= Login` matches `<button>Button loGIN (click me)</button>`.
-- Text body can be escaped with single or double quotes for precise matching, insisting on exact match, including specified whitespace and case. This means `text="Login "` will only match `<button>Login </button>` with exactly one space after "Login". Quoted text follows the usual escaping rules, e.g. use `\"` to escape double quote in a double-quoted string: `text="foo\"bar"`.
-- Text body can also be a JavaScript-like regex wrapped in `/` symbols. This means `text=/^\\s*Login$/i` will match `<button> loGIN</button>` with any number of spaces before "Login" and no spaces after.
-- Input elements of the type `button` and `submit` are rendered with their value as text, and text engine finds them. For example, `text=Login` matches `<input type=button value="Login">`.
-
-Malformed selector starting and ending with a quote (either `"` or `'`) is assumed to be a text selector. For example, Playwright converts `page.click('"Login"')` to `page.click('text="Login"')`.
-
-`text` engine open pierces shadow roots similarly to `css`, while `text:light` does not. Text engine first searches for elements in the light dom in the iteration order, and then recursively inside open shadow roots in the iteration order. It does not search inside closed shadow roots or iframes.
-
-### id, data-testid, data-test-id, data-test selector engines
-
-Attribute engines are selecting based on the corresponding attribute value. For example: `data-test-id=foo` is equivalent to `css=[data-test-id="foo"]`, and `id:light=foo` is equivalent to `css:light=[id="foo"]`.
