Hi, I've copied a header from ui.mantine. https://ui.mantine.dev/component/header-tabs/
I didn't change a line of code, I only created the component files.
I don't have the same look, for example, on the unstyles button (user button) there is no padding.
Can't figure out what is wrong. I didn't use a template, I've installed the mantine. I installed the postcss dependencies and I've added the import '@mantine/core/styles.css'; on the layout page (using app router on nextjs 14).
Any ideas what could be missing?
