This page shows you, how to configure custom image effects on top of existing ones.

This setting can also be overridden by your front matter.

If you don't configure anything in your hugo.toml, the image effects default to

Default Values

{{< multiconfig >}} imageEffects.border = false imageEffects.dataurl = false imageEffects.inlinecontent = false imageEffects.lazy = true imageEffects.lightbox = true imageEffects.shadow = false {{< /multiconfig >}}

Configuration

{{% badge style="cyan" icon="gears" title=" " %}}Option{{% /badge %}} You can change these settings in your hugo.toml and add arbitrary custom effects as boolean values (like bg-white in the below snippet).

{{< multiconfig file=hugo section=params >}} imageEffects.bg-white = true imageEffects.border = true imageEffects.lazy = false {{< /multiconfig >}}

This would result in

{{< multiconfig >}} imageEffects.bg-white = true imageEffects.border = true imageEffects.dataurl = false imageEffects.inlinecontent = false imageEffects.lazy = false imageEffects.lightbox = true imageEffects.shadow = false {{< /multiconfig >}}

Example

With this configuration in effect, the following URL

![Minion](https://octodex.github.com/images/minion.png)

would result in

<img src="https://octodex.github.com/images/minion.png" loading="lazy" alt="Minion" class="bg-white border lightbox">

Styling Effects

If the resulting effect value is true a class with the effect's name will be added.

Styles for default effects are contained in the theme. Add styles for your custom effects to layouts/partials/content-header.html.

For the above custom effect you could add the following style:

<style>
img.bg-white {
  background-color: white;
}
</style>
