# CSS Packages

All styles are inside of CSS files. In order to ensure flexibility with legacy code, styles are packed into [several combinable packages](/uilib/usage/customisation/styling) like:

- **dnb-ui-core**
- **dnb-ui-basis**
- **ui-theme-basis**
- **ui-theme-components**
- etc.

## CSS Reset

The package **dnb-ui-core** loads by default a CSS `reset/normalize`, optimized for the DNB Eufemia styles and browser universalization.

On [legacy code projects](/uilib/usage/customisation/styling#how-to-deal-with-existing-styles), rather use **dnb-ui-basis** [in combination with](/uilib/usage/customisation/styling#core-style) `.dnb-core-style`.
