Cookie-Script has plenty of customization options available, like custom colors and different design options. You can also disable or hide any part of the cookie consent banner. However, in some cases, this is not enough and more customization is needed. Sometimes users want to have some very special styling, like custom typography or border styles.
This is exactly why we have introduced a custom CSS styling option. It can be found in the Appearance tab.
In short, it does exactly what you expect it to do: it allows users to add custom CSS styling to the existing styles of cookie consent popup. Just fill in necessary styles and they will be included in the generated source code of cookie consent banner.
