An alternative way of writing an `if` statement and then referencing the same value is to use `with` instead. `with` rebinds the context (`.`) within its scope and skips the block if the variable is absent or unset.

The following example checks for a [user-defined site variable](/variables/site/) called `twitteruser`. If the key-value is not set, the following will render nothing:
|
|
|
|
{{% code file="layouts/partials/twitter.html" %}}
|
|
```html
|
|
{{with .Site.Params.twitteruser}}<span class="twitter">
|
|
<a href="https://twitter.com/{{.}}" rel="author">
|
|
<img src="/images/twitter.png" width="48" height="48" title="Twitter: {{.}}"
|
|
alt="Twitter"></a>
|
|
</span>{{end}}
|
|
```
|
|
{{% /code %}}
