[Bug] Page styles bleeding into displayed components

[luchillo17]

Describe the bug
The components that should display the changes being done to the theme are being affected by the base theme of the page: https://github.com/jnsahaj/tweakcn/blob/main/app/globals.css

To Reproduce
Steps to reproduce the behavior:

1. Grab any component with a border in any example theme, see how the input borders are affected by CSS at the page level and those are not included in the theme code.

Expected behavior
I expected the theme being modified to be sandboxed, so the general theme of the TweakCN page doesn't affect the examples and the theme being edited.

Screenshots

My theme in the page:

My theme in my app:

Desktop (please complete the following information):

• OS: Windows 11
• Browser: Chrome
• Version: 140.0.7339.128

Additional context
Add any other context about the problem here.

Can you verify if you have this in your globals.css? These rules are set automatically when you set up shadcn and as you can see, they apply the color --border to the border. The tool is meant to replace onlt the shadcn tokens, but won't set the rest of the configuration.

In your case the border-color property in your components that do have a border is probably not defined.

@layer base {
  * {
    @apply border-border outline-ring/50;
  }
  body {
    @apply bg-background text-foreground;
  }
}

should we include these properties in our exported globals.css?

I see that people have to manually copy root, .dark and @theme inline, but maybe we should just recreate the default tailwind css file and share that.

bonus points if we can make the sections collapsible (like you can do in a code editor)

Sure, would be nice. Also, I had this open PR #200 where you can pick what to export, worked nicely to opt out font vars so far.

I could see people adding customizations that would end up overridden, it happened to me a couple of times when I first tried Tweakcn, maybe add instructions to add a custom.css module imported in globals.css to separate tweakcn output from app styles? or maybe the other way around, tweacn-theme.css to be imported in the global one?

@layer base {

• {
  @apply border-border outline-ring/50;
  }
  body {
  @apply bg-background text-foreground;
  }
  }

In my case I have this under the part I copy pasted from Tweakcn:

* {
  color-scheme: light dark;
  border-color: var(--color-border);
}

@layer base {
  * {
    @apply border-border outline-ring/50;
  }
  body {
    @apply bg-background text-foreground;
  }

  html,
  body {
    height: 100%;
  }

  div[data-lastpass-icon-root] {
    display: none !important;
  }

  button:not(:disabled),
  [role='button']:not(:disabled) {
    cursor: pointer;
  }
}

@utility scrollbar-thin {
  scrollbar-width: thin;
  scrollbar-color: var(--color-border) transparent;

  &::-webkit-scrollbar {
    width: 8px;
  }
}

@utility scrollbar-gutter-stable {
  scrollbar-gutter: stable;
}

@utility scrollbar-gutter-both {
  scrollbar-gutter: stable both-edges;
}

I think this line could be causing the issue
border-color: var(--color-border);
