 In any programming language, the code needs to make decisions and carry out actions accordingly depending on different inputs. For example, in a game, if the player's number of lives is 0, then it's game over. In a weather app, if it is being looked at in the morning, show a sunrise graphic; show stars and a moon if it is nighttime. In this article, we'll explore how so-called conditional statements work in JavaScript.

 ## Summary
 
 In this article, we have covered the fundamental information you need to know about numbers in JavaScript, for now. You'll see numbers used again and again, all the way through your JavaScript learning, so it's a good idea to get this out of the way now. If you are one of those people that doesn't enjoy math, you can take comfort in the fact that this chapter was pretty short.

 ## Summary
 
 You should now have a good idea of how to work with objects in JavaScript — including creating your own simple objects. You should also appreciate that objects are very useful as structures for storing related data and functionality — if you tried to keep track of all the properties and methods in our `person` object as separate variables and functions, it would be inefficient and frustrating, and we'd run the risk of clashing with other variables and functions that have the same names. Objects let us keep the information safely locked away in their own package, out of harm's way.

 There's one last essential concept about functions for us to discuss — return values. Some functions don't return a significant value, but others do. It's important to understand what their values are, how to use them in your code, and how to make functions return useful values. We'll cover all of these below.
 
@@ -173,21 +173,15 @@ Some extra function-related tips:
 - Look at another example of writing _error handling_ into functions. It is generally a good idea to check that any necessary parameters are validated, and that any optional parameters have some kind of default value provided. This way, your program will be less likely to throw errors.
 - Think about the idea of creating a _function library_. As you go further into your programming career, you'll start doing the same kinds of things over and over again. It is a good idea to create your own library of utility functions to do these sorts of things. You can copy them over to new code, or even just apply them to HTML pages wherever you need them.

This allows you to style elements at specific heading levels at once, rather than matching and styling them individually.
+

+## Syntax
+
+```css-nolint
+:heading([ <An+B> [, <An+B>]* | even | odd ]) {
+  /* ... */
+}
+```
+
+### Parameters
+
+The `:heading()` pseudo-class function takes a comma-separated list of `An+B` expressions or keyword values that describe a pattern for matching heading elements.
+
+#### Keyword values
+
+- `odd`
+  - : Represents the heading elements whose numeric position is odd: `<h1>`, `<h3>`, and `<h5>`.
+- `even`
+  - : Represents the heading elements whose numeric position is even: `<h2>`, `<h4>`, and `<h6>`.
+
+#### Functional notation
+
+- `<An+B>`
+  - : Represents the heading elements whose numeric position matches the pattern `An+B`, for every positive integer or zero value of `n`, where:
+    - `A` is an integer step size,
+    - `B` is an integer offset,
+    - `n` is all nonnegative integers, starting from 0.
+
+    It can be read as the `An+B`-th element of a list. The `A` and `B` must both have {{cssxref("&lt;integer&gt;")}} values.
+
+## Usage notes
+
+The `:heading()` functional pseudo-class matches only elements that are semantically recognized as headings. It does not match elements with a [`role="heading"`](/en-US/docs/Web/Accessibility/ARIA/Reference/Roles/heading_role) attribute, nor does it respect the ['aria-level'](/en-US/docs/Web/Accessibility/ARIA/Reference/Attributes/aria-level) ARIA attribute.
+
+## Examples
+
+### Using keyword parameters
+
+In this example, the `odd` keyword matches headings with odd-numbered levels, which are `<h1>` and `<h3>`. The `even` keyword is used to target even-numbered heading levels, `<h2>` and `<h4>`.
+
+```html
+<h1>Heading 1</h1>
+<h2>Heading 2</h2>
+<h3>Heading 3</h3>
+<h4>Heading 4</h4>
+```
+
+```css
+:heading(odd) {
+  color: tomato;
+}
+:heading(even) {
+  color: slateblue;
+}
+```
+
+{{EmbedLiveSample("Keyword_example", "", "215")}}
+
+### Using the `An+B` notation
+
+```html
+<h1>Science</h1>
+<h2>Physics</h2>
+<h3>Atomic, molecular, and optical physics</h3>
+<h4>Optical physics</h4>
+<h5>X-Rays</h5>
+<h6>Discovery</h6>
+```
+
+```css hidden
+main {
+  display: flex;
+  justify-content: space-around;
+}
+```
+
+```css
+/* Targets headings <h3> and <h4> */
+:heading(3, 4) {
+  font-weight: 100;
+}
+/* Targets headings in reverse starting from <h3> */
+:heading(-n + 3) {
+  color: tomato;
+}
+/* Targets every third heading starting from <h1> */
+:heading(3n + 1) {
+  font-style: italic;
+}
+/* Targets headings after level 5 */
+:heading(n + 5) {
+  color: slateblue;
+}
+
+In this example:
+- `:heading(3, 4)` matches the `<h3>` and `<h4>` elements
+- `:heading(-n + 3)` matches heading elements in reverse, so `<h3>`, `<h2>`, and `<h1>`
+- `:heading(3n + 1)` matches every third (`3n`) heading element starting from `<h1>`, so this would include `<h1>` and `<h4>`
+- `:heading(n + 5)` matches heading elements starting from `<h5>` and will include `<h6>`
