# Table of Contents
Navigate the hierarchy of headings for the current page.
```html
// Error loading file, please report this issue.
```
## Deep Linking
Browsers allow you to deep link to any element via the ID. This is accomplished with an anchor tag and hashed (`#`) href value. When interacting with these anchors, the viewport will automatically attempt to scroll the `` element and bring the element into view.
```html
Some Example Heading
```
```html
Some Example Heading
```
> TIP: If you abstract scrolling away from the `` element, this will not work.
## Scroll Behavior
You may optionally choose to implement a smooth [scroll behavior](https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-behavior) using CSS.
```html
```
```css
body {
scroll-behavior: smooth;
}
```
## Generate a Slug
The following provides a barebones implementation for generating a slug based on a heading text value.
```ts
function generateSlug(text: string, prefix?: string = '', suffix?: string = '') {
// Format the slug from the text value.
const slug = text
.toLowerCase()
.replaceAll(/[^a-zA-Z0-9 ]/g, '')
.replaceAll(' ', '-')
.toLowerCase();
// Note that you can optionally apply a prefix/suffix.
return `${prefix}${slug}${suffix}`;
}
// Usage
generateSlug('An Example Header'); // result: an-example-header
generateSlug('An Example Header', 'skeleton-'); // result: skeleton-an-example-header
generateSlug('An Example Header', '', '-skeleton'); // result: an-example-header-skeleton
```
