## 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):

✋️ 🚫 😟, 👆 💪 ⚒ 🎢 🇪🇸 🇪🇸 & ⤴️ 💬 🎚 🩺.

🚥 👆 💪 👈, ✍ `mkdocs.yml` 👆 🆕 🇪🇸, ⚫️ 🔜 ✔️ 🕳 💖:

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

🔀 👈 🇪🇸 ⚪️➡️ `xx` (⚪️➡️ 👆 🇪🇸 📟) `en`.

⤴️ 👆 💪 ▶️ 🖖 💽 🔄.

#### 🎮 🏁

    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_.

## 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">

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

But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).
