# Typography
Our design system includes a typographic scale based on the scale of fifths to create six harmonic levels of font sizes. These will guide the basic sizing of headlines, body text and spacing in a graphics page.
Our Reuters Graphics components include a basic typography system designed to make it easy to incorporate clean, balanced type styles in your project.
The typographic scale is set using the CSS variable in the theme component. You can customise them if you need a bespoke typesetting for your project.
## The type system
<img
className="feature"
src={TypeGuides}
width="100%"
style={{ margin: '3rem 0' }}
/>
## How it works
<img
className="feature"
src={Typeset}
width="100%"
style={{ margin: '3rem 0' }}
/>
Text styles are composed using [CSS variables](/docs/theming-css-variables--page) for size, family and colours from the `Theme`. The font size inherits `--theme-scale-size-*` and font family inherits `--theme-typeface-*`. See which CSS vars flow in to the type system in the [How to use text styles](/docs/typography-how-to-use--text-styles) section.
## Default usage
In your projects, you will use the typographic styles as per the function
- Page title, subheads and section titles
- Body copy
- Graphic descriptions, captions and other notes
The styles are also applied to native HTML elements like the `H` and `p` tags.
> For Graphics Kit users, the typographic styles are already imported and applied to the individual components.
The typography system includes all the levels of text heirarchy you'll need for graphics pages, including page title, subheads, section titles, body copy, graphic descriptions, captions and other notes.

# Using the type system
## Type style heirarchy
The type styles consist of 3 elements: size, typeface and colour. TKTKTK
## Using type styles
Type styles are automatically applied to native HTML elements like `h` and `p` tags and to certain combinations of elements that represent specific text components.
```svelte
<div>
<h2>Here's a section title</h2>
<p>and some text to go with it...</p>
</div>
<div class="endnote">
<p><strong>Editors:</strong> Simon Scarr</p>
</div>
```
Apply text styles to any element using CSS classes that correspond to each text element type.
```svelte
<div class="font-subhed-1">Subhed</div>
<p class="font-note-1">Sans-serif text...</p>
```
The following text style elements and corresponding classes are available:
| Style | class | mixin | CSS vars used from Theme |
| ------------- | ---------------- | --------------- | -------------------------------------------------------------------------------------------- |
| Page title | `.font-hed` | `font-hed` | `--theme-font-size-hed`, `--theme-font-family-hed` , `--theme-colour-text-primary` |
| Section title | `.font-subhed-1` | `font-subhed-1` | `--theme-font-size-subhed-1`, `--theme-font-family-subhed` , `--theme-colour-text-primary` |
| Subhed | `.font-subhed-2` | `font-subhed-2` | `--theme-font-size-subhed-2`, `--theme-font-family-subhed` , `--theme-colour-text-primary` |
| Smallhed | `.font-subhed-3` | `font-subhed-3` | `--theme-font-size-subhed-3`, `--theme-font-family-subhed` , `--theme-colour-text-secondary` |
| Body text | `.font-body` | `font-body` | `--theme-font-size-body`, `--theme-font-family-body` , `--theme-colour-text-primary` |
| Body note | `.font-note-1` | `font-note-1` | `--theme-font-size-note-1`, `--theme-font-family-note` , `--theme-colour-text-primary` |
| Endnotes | `.font-note-2` | `font-note-2` | `--theme-font-size-note-2`, `--theme-font-family-note` , `--theme-colour-text-secondary` |
| Footnotes | `.font-note-3` | `font-note-3` | `--theme-font-size-note-3`, `--theme-font-family-note` , `--theme-colour-text-secondary` |

### Type sizes
The following classes apply specific text sizes to any element:
| level | class | mixin | CSS vars used from Theme |
| ----- | -------------- | ------------- | ------------------------ |
| 1 | `.font-size-1` | `font-size-1` | `--theme-scale-size-1` |
| 2 | `.font-size-2` | `font-size-2` | `--theme-scale-size-2` |
| 3 | `.font-size-3` | `font-size-3` | `--theme-scale-size-3` |
| 4 | `.font-size-4` | `font-size-4` | `--theme-scale-size-4` |
| 5 | `.font-size-5` | `font-size-5` | `--theme-scale-size-5` |
| 6 | `.font-size-6` | `font-size-6` | `--theme-scale-size-6` |
> The text sizes are always a multiple of `size-base = 1.375`. On mobile
> {max-width:510px}, levels 1, 2, 3, 4 scale down to `size-base-mobile = 1.125`
