# theme

`theme` should be an HTML class, which will be added to :

* the overlay `.bp3-dialog` elements
* the on-page menu `.bp3-card` element
* the context menu `.bp3-popover` element

You can use it to facilitate custom theming.

## Blueprint Dark Theme

{% hint style="success" %}
Using `theme: "bp3-dark"` will apply Blueprint's own dark theme to the extension's interface, without needing any additional CSS rules.
{% endhint %}
