## Change the Theme

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial002.py!}
```

That configuration would change the syntax highlighting color theme:

<img src="/img/tutorial/extending-openapi/image04.png">

def on_files(files: Files, *, config: MkDocsConfig) -> Files:
    resolve_files(items=config.nav or [], files=files, config=config)
    if "logo" in config.theme:
        resolve_file(item=config.theme["logo"], files=files, config=config)
    if "favicon" in config.theme:
        resolve_file(item=config.theme["favicon"], files=files, config=config)
    resolve_files(items=config.extra_css, files=files, config=config)

<img src="/img/tutorial/extending-openapi/image03.png">

## Das Theme ändern

Auf die gleiche Weise könnten Sie das Theme der Syntaxhervorhebung mit dem Schlüssel `syntaxHighlight.theme` festlegen (beachten Sie, dass er einen Punkt in der Mitte hat):

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial002.py!}
```

Obige Konfiguration würde das Theme für die Farbe der Syntaxhervorhebung ändern:

from fastapi import FastAPI

app = FastAPI(swagger_ui_parameters={"syntaxHighlight.theme": "obsidian"})


@app.get("/users/{username}")
async def read_user(username: str):

    assert response.status_code == 200, response.text
    assert (
        '"syntaxHighlight": false' not in response.text
    ), "not used parameters should not be included"
    assert (
        '"syntaxHighlight.theme": "obsidian"' in response.text
    ), "parameters with middle dots should be included in a JSON compatible way"
    assert (
        '"dom_id": "#swagger-ui"' in response.text
    ), "default configs should be preserved"

Se você precisar fazer isso, edite o `mkdocs.yml` para sua nova linguagem, teremos algo como:

```YAML hl_lines="5"
site_name: FastAPI
# Mais coisas
theme:
  # Mais coisas
  language: xx
```

Altere essa linguagem de `xx` (do seu código de linguagem) para `en`.

Então você poderá iniciar novamente o _servidor ao vivo_.

INHERIT: ../en/mkdocs.maybe-insiders.yml
site_name: FastAPI
site_description: FastAPI framework, high performance, easy to learn, fast to code, ready for production
site_url: https://fastapi.tiangolo.com/
theme:
  name: material
  custom_dir: ../en/overrides
  palette:
  - media: '(prefers-color-scheme: light)'
    scheme: default
    primary: teal
    accent: amber
    toggle:
      icon: material/lightbulb
      name: Switch to dark mode

Если возникла такая необходимость, отредактируйте `mkdocs.yml` для Вашего нового языка. Это будет выглядеть как-то так:

```YAML hl_lines="5"
site_name: FastAPI
# More stuff
theme:
  # More stuff
  language: xx
```

Измените `xx` (код Вашего языка) на `en` и перезапустите сервер.
