## Opening Links

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} {{% badge style="green" icon="fa-fw fab fa-markdown" title=" " %}}Front Matter{{% /badge %}} By default, external links open in a new tab. To change this, use the `externalLinkTarget` setting with a proper [link target](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#target).

For example, this will open links in the same tab

{{< multiconfig >}}
externalLinkTarget = '_self'
{{< /multiconfig >}}

## Enabling Link and Image Link Warnings

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} {{% badge style="green" icon="fa-fw fab fa-markdown" title=" " %}}Front Matter{{% /badge %}} You can use `link.errorlevel` and `image.errorlevel` to control what should happen if a local link can not be resolved to a resource.

If not set or empty, any unresolved link is written as given into the resulting output. If set to `warning` the same happens and an additional warning is printed in the built console. If set to `error` an error message is printed and the build is aborted.

Please note that this can not resolve files inside of your `static` directory. The file must be a resource of the page or the site.

Link warnings are also available for the [include](shortcodes/include#enabling-link-warnings) and [openapi](shortcodes/openapi#enabling-link-warnings) shortcodes.

{{< multiconfig >}}
link.errorlevel = 'warning'
image.errorlevel = 'warning'
{{< /multiconfig >}}
