# Typography theming
Material Design typography theming can be used to create typographic styles that
reflect your brand or style by defining a set of type scales which will be used
throughout your app. You can use type scales to customize the appearance of text
in Material components.

## Style values
Style values are a combination of the following:
* Font face name and weight
* Font size
* Letter spacing
* Text transformation (e.g., all caps)
## Customization
The components included in the Material Design Library reference these themeable
text attributes, enabling you to easily change text appearance across your whole
application. If you display text in `TextView`s or create custom components,
consider referencing one of these text attributes where it makes sense.
You can change the look of any text style by creating a new style and setting it
in your theme:
```xml
```
```xml
```
## Downloadable fonts
Android O and Android Support Library 26 add support for [Downloadable
Fonts](https://developer.android.com/guide/topics/ui/look-and-feel/downloadable-fonts.html).
This allows you to easily use the entire Google Fonts Open Source collection
without bundling a font with your apk. Find more information at
https://developers.google.com/fonts/docs/android.
**Note:** If you want to use a Downloadable Font before Android O, make sure you
are using `AppCompatTextView` or that you are loading the font yourself with
`ResourcesCompat.getFont()`.
