CSS settings do not apply

Hi

Excellent plugin congratulations.

I have the Roll Block switcher active and I want to reduce the width a bit so that it looks like this: https://snipboard.io/JDMQmh.jpg

But when I apply CSS in my theme
.woocs_auto_switcher {
width: 47px;
}
This is disabled.

How can I do to apply the CSS?

Thanks
