update css

Yes, those styles can move directly into a **`PostDetail.razor.css`** file.

Because your `PostDetail.razor` contains the HTML with the class `class="btn-link share-btn"`, Blazor will correctly apply the isolated styles to that button.

### Refactoring Steps

1. **Create** a file named `Pages/PostDetail.razor.css` (or wherever your page is located).
2. **Paste** the `.share-btn` styles there.
3. **Delete** them from `site.css`.

### Important Note: The "Deep" Selector Rule

There is one thing to be aware of when using CSS isolation on Pages that contain child components (like your `ReaderBadge` or `MarkdownRenderer`).

* **Isolated CSS** in `PostDetail.razor.css` will **only** affect HTML elements defined *inside* `PostDetail.razor`.
* It will **not** affect HTML elements inside `MarkdownRenderer` unless you use the `::deep` combinator.

Since your `.share-btn` is defined directly in the `PostDetail.razor` file, it works perfectly without any changes.

### One Small Enhancement

Since you are using a standard `<button>` with a `share-btn` class, you might want to ensure the button doesn't have the default "grey box" browser styling. You can add these lines to your `PostDetail.razor.css` to keep it clean:

```css
/* PostDetail.razor.css */

.share-btn {
    display: inline-flex;
    align-items: center;
    gap: 0.25rem;
    font-size: 0.875rem;
    color: var(--color-text-muted);
    /* Reset button styles if not already handled by btn-link */
    background: none;
    border: none;
    padding: 0;
    cursor: pointer;
}

.share-btn:hover {
    color: var(--color-primary);
    text-decoration: underline;
}

.share-btn svg {
    margin-top: -2px; /* Fine-tune icon alignment */
}

.share-btn.success {
    color: var(--color-success);
}

```

### Why this is better

By moving these styles to the page level:

1. **Bundle Size:** Your `site.css` stays focused on global layout (colors, fonts, grids).
2. **Naming Safety:** You could have a completely different `.share-btn` on a "User Profile" page or "Image Gallery" and they would never conflict.
3. **Maintenance:** When you decide to change the share icon or color, you know exactly which file to open.

Would you like me to help you create the **`sharePost`** JavaScript function in your `site.js` to actually make that button work with the native browser share menu?
