**Make sure to import the CSS from `npf_renderer.utils.BASIC_LAYOUT_CSS`!**

```python
with open("basic_layout.css", "w") as file:
    file.write(npf_renderer.utils.BASIC_LAYOUT_CSS)
```

```html
<link rel="stylesheet" href="basic_layout.css">
```

`format_npf` will return placeholder HTML for any blocks it doesn't support.


<details>
<summary>Unsupported blocks</summary>

```html
<div class="post-body">
  <p class="text-block"> This text block is supported but the next block is not! </p>
  <div class="unsupported-content-block">
    <div class="unsupported-content-block-message">
      <h1>Unsupported content placeholder</h1>
      <p>Hello! I'm a placeholder for the unsupported "poll" type NPF content block. Please report me!</p>
    </div>
  </div>
</div>
```

</details>

In the event that it cannot format anything an empty div will be returned

## Installation

```bash
pip install npf-renderer
```

## Advanced

You can pass in a custom URL handler function to `format_npf` to replace any links within the NPF tree.

```python
def url_handler(url):
    url = urllib.parse.urlparse(url)

    if url.hostname.endswith("example.com"):
        return url._replace(netloc="other.example.com").geturl()

format_npf(contents, layouts, url_handler=url_handler)
```

You can also pass in an subclassed `Parser`, `LayoutParser` or `Formatter` object to `format_npf` to customize its behavior on all parts of the chain.
