# Basic example

As you can see in the screenshot below most DOM Element get assigned a class starting by kcSomething. Example kcFormHeaderClass.

No styles rules get assigned to those classes they are only here for you to use as target for your custom CSS.

So if you're not very interested in all the bells and whistles Keycloakify offers, you can just create a CSS[^1] file and just start customizing the page:

<figure><img src="/files/A7XjOTIkE9kgzB8xw2OB" alt=""><figcaption><p>Applying a red border to all the DOM element with the kcFormHeaderClass class</p></figcaption></figure>

<figure><img src="/files/6IzIGbxF1rpVyIpFc4Hq" alt="" width="375"><figcaption><p>The red border gets applied</p></figcaption></figure>

Up next:

{% content-ref url="/pages/u9uURKCWrEvhExws0OYR" %}
[Removing the default styles](/keycloakify/v10/customization-strategies/css-level-customization/removing-the-default-styles.md)
{% endcontent-ref %}

[^1]: ...or LESS or SASS

## 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://docs.keycloakify.dev/keycloakify/v10/customization-strategies/css-level-customization/basic-example.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.
