# Adding Custom CSS

Custom CSS allows you to fully customize your referral program to make it fully match your website. You can use custom CSS to add support for your font, your brand colors, and much more.

{% hint style="warning" %}
Add custom CSS, only if you have knowledge of HTML and CSS.
{% endhint %}

To get started go to the advance section for Bamboo [here](https://app.trybeans.com/bamboo/advance).\
\
Enter your Custom CSS in the Custom CSS field and save your changes. Be aware that due to caching it might take up to 15 minutes for your changes to reflect on your website\ <br>

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.trybeans.com/bamboo/faq/referral-program-page-customization-with-css.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
