# Customize Look & Feel

ONEWEB mainly controls the look and feel of the forms through CSS. Cascading Style Sheets (CSS) is a language for describing how content is presented. Its purpose is to help separate content (HTML) from the presentation.

ONEWEB provides a default custom CSS that the users can edit to create their individual styles. The name of the file is \<CurrentTheme>\_Custom\_Style.css. To find the file, open Eclipse IDE, on the Project Explorer pane, go to on **/MasterWeb/WebContent/theme/\<CurrentTheme>** folder, and open **\<CurrentTheme>\_Custom\_Style.css.** For an example shown below, CurrentTheme is Responsive2016.

This file is blank when you start with ONEWEB. You can add any custom css that you want to apply to your project here. The styles that you define here are applicable across all Smart Forms. For e.g. to change the header color please add the below snippet to the custom CSS file.

Or to add the default background to all text fields add the following snippet.

Once the changes are saved, right-click the server and select Publish from the menu. The state changes to Synchronized once the project has been deployed to the server.&#x20;

## 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.oneweb.tech/oneweb/design-and-develop-oneweb-apps/design-and-develop-ux-ui/ux-ui-customization/smart-form-customization/customize-look-and-feel.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.
