```

Neste exemplo, ele seria vinculado a um arquivo CSS em `static/styles.css` com:

```CSS hl_lines="4"
{!../../../docs_src/templates/static/styles.css!}
```

Ihre neue Dateistruktur könnte so aussehen:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static/
```

### Die Dateien herunterladen

Laden Sie die für die Dokumentation benötigten statischen Dateien herunter und legen Sie diese im Verzeichnis `static/` ab.

Sie können wahrscheinlich mit der rechten Maustaste auf jeden Link klicken und eine Option wie etwa `Link speichern unter...` auswählen.

.
├── app
│   ├── __init__.py
│   ├── main.py
```

接下来，创建存储静态文件的文件夹。

新的文件架构如下：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static/
```

### 下载文件

下载文档所需的静态文件，把文件放到 `static/` 文件夹里。

右键点击链接，选择**另存为...**。

**Swagger UI** 使用如下文件：

    Use Python types to have great editor support.

    Have a powerful dependency injection system. Find a way to minimize code repetition.

    So, with the same Python type declaration, **FastAPI** gives you data validation.

    Notice that the error also clearly states exactly the point where the validation didn't pass.

    This is incredibly helpful while developing and debugging code that interacts with your API.
