# Use our stylesheet

{% hint style="info" %}
Now we have a design system with customizable web components. [Learn more here](/xena-developer/user-interface/xena-design-system.md)
{% endhint %}

Xena strives for a unified and simple look. This help us build a UI that is easy to use and have recognizable patterns. Because Xena is used by a wide variety of businesses we have to take backward compatibility into consideration.

Xenas [layout and classes](/xena-developer/user-interface/styleguide/layout.md) are *based* on Bootstrap version 3.3. For icons [we use Font Awesome 5 Pro](/xena-developer/user-interface/styleguide/icons.md). And we have our own styling as well.

If you want to reuse Xena’s look’n’feel in your plugins, you can reference a subset of our stylesheet designed for plugins:

```markup
<link href="https://my.xena.biz/Content/css/xena-plugin.css" rel="stylesheet" />
```
