Button component and use without writing any classes,h-10 py-2 px-4 bg-primary.... applied. You can overwrite those styles by writing classes like you would anywhere else, because the components use tailwind-merge under the hood. bg-blue-500 on a component, you might have to change it to bg-red-300 when you copy and paste it into another project. Across all of your components, it can be a pain. But if you just use bg-primary, then you just need to change the theme or css variable in one place.
