# Comment ViewHelper `<f:comment>` {#typo3fluid-fluid-comment}

> [!NOTE]
> This reference is part of the documentation of Fluid Standalone.
> If you are working with Fluid in TYPO3 CMS, please refer to

This ViewHelper prevents rendering of any content inside the tag.

Contents of the comment will **not be parsed** thus it can be used to
comment out invalid Fluid syntax or non-existent ViewHelpers during
development.

Using this ViewHelper won't have a notable effect on performance,
especially once the template is parsed. However, it can lead to reduced
readability. You can use layouts and partials to split a large template
into smaller parts. Using self-descriptive names for the partials can
make comments redundant.

## Examples {#examples}

### Commenting out fluid code {#commenting-out-fluid-code}

```php
Before
<f:comment>
    This is completely hidden.
    <f:debug>This does not get rendered</f:debug>
</f:comment>
After

```

Output:

```php
Before
After
```
