# Custom Liquid

This is an advanced functionality that requires additional developer skills. More about Liquid can be read [<mark style="color:blue;">here</mark>](https://shopify.dev/api/liquid).

### Transparent header

Allows the header to overlay the section when a transparent header is used.

**Use inverted header colors**\
Enable the option to link the color of the Header elements, such as navigation menus, Search, Compare, Account, and Cart icons, with the "[<mark style="color:blue;">Background</mark>](/unicorn-shopify-theme/theme-settings/colors.md#background)" item under *Theme settings -> Colors -> Primary colors*. If the option is disabled, the color of the Header elements is related to the "[<mark style="color:blue;">Base</mark>](/unicorn-shopify-theme/theme-settings/colors.md#base)" item.
