Modifying the fonts settings file for font customization

You customize the fonts for the text that is displayed on native elements of your mobile app, for example, to conform to your company's branding or to improve readability. After you upload custom fonts, modify the fonts list for your mobile app.

Before you begin: Upload the font files. For more information, see Uploading custom font files.

In the header of Dev Studio, in the search field, enter pyMobileFontsList, and then press Enter.
In the search results, expand the list of matches by clicking the arrow next to the pyMobileFontsList link, and then open the text file rule by clicking the link for the UI-Kit 7 ruleset.
On the pyMobileFontsList text file rule configuration screen, save a copy of the text file rule in the context of your application by clicking Save as > Specialize by class or ruleset, and then selecting your application in the Context area.
For each of the font files that you upload, in the pyMobileFontsList rule, add a JSON array, according to the following template:
```
{
    url: "myAppName/MyFontNameRegular.ttf", 
    fontFamily: "MyFontName", 
    type: "text"
}
```
The parameters define the following attributes:

url

Defines the URL address of the font file.

fontFamily

Defines the name of the font.

type

Defines the type of the font.
Click Save.
