Hi @pseudo trellis. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Based on the knowledge sources provided, there isn't specific information about limiting the size of a LinkCard component to match its description size in Starlight (which is an Astro documentation theme).
The LinkCard component in Starlight has a fixed structure with predefined styling. According to the documentation, it accepts the following props:
title(required): The title of the link card to displayhref(required): The URL to link todescription(optional): A description to display below the title
Link Cards documentation shows how to use the component but doesn't mention any size customization options specifically tied to the description length.
If you want to customize the appearance of LinkCard components, you would likely need to use custom CSS. Starlight does support custom CSS styling as mentioned in the CSS & Styling guide, where you can add your own CSS files to modify the default styles.
You could potentially create custom CSS rules targeting the LinkCard component to adjust its size based on your specific needs, but there's no built-in prop or option specifically for limiting the card size to match the description size.
I hope this helps! Let me know if you need more information about customizing Starlight components with CSS.

@hasty stag How to do it with custom CSS ?
hasty stagBOT
Let me check the knowledge base for you again. One moment! :books:
To customize the LinkCard component size with custom CSS in Starlight, you can follow these steps:
- First, create a custom CSS file in your project:
/* src/styles/custom.css */
.sl-link-card {
/* Override the default height/size behavior */
height: auto;
min-height: 0;
}
.sl-link-card .sl-flex {
/* Make the content fit to its actual size */
height: auto;
}
- Add this CSS file to your Starlight configuration in
astro.config.mjs:
import { defineConfig } from 'astro/config';
import starlight from '@astrojs/starlight';
export default defineConfig({
integrations: [
starlight({
title: 'Your Site Title',
customCss: [
'./src/styles/custom.css',
],
}),
],
});
This approach uses Starlight's custom CSS styling feature to override the default styles of the LinkCard component.
If you need more specific styling, you might want to inspect the LinkCard component in your browser's developer tools to identify the exact class names and structure. The implementation of the LinkCard component can be found in LinkCard.astro if you need to reference the original structure.
Remember that if these styles conflict with your component's appearance, you can use the not-content class as mentioned in the Using components guide to disable Starlight's default content styling.

@hasty stag Can I change only some LinkCard with a class ?
hasty stagBOT
Let me check the knowledge base for you again. One moment! :books:
Yes, you can selectively style specific LinkCard components by passing a custom class to them. In Astro components like LinkCard, you can pass a class prop that will be applied to the component.
Here's how to do it:
- First, create your custom CSS with the styles you want to apply to specific LinkCards:
/* src/styles/custom.css */
.compact-card {
height: auto;
min-height: 0;
}
.compact-card .sl-flex {
height: auto;
}
-
Add this CSS file to your Starlight configuration as shown previously.
-
Then, when using the LinkCard component, pass your custom class:
import { LinkCard } from '@astrojs/starlight/components';
<LinkCard
title="Regular Card"
href="/some-link/"
description="This card will have the default styling."
/>
<LinkCard
title="Compact Card"
href="/another-link/"
description="This card will have compact styling."
class="compact-card"
/>
However, there's an important detail to note: In Astro, HTML attributes like class don't automatically pass through to child components. The LinkCard component needs to be set up to accept and use the class prop.
As explained in the Astro documentation on passing a class to a child component, the component needs to be configured to accept and use the class:
---
// Inside the component
const { class: className, ...rest } = Astro.props;
---
<div class={className} {...rest}>
<slot/>
</div>
If the LinkCard component in Starlight doesn't already handle the class prop this way, you might need to create your own custom version of the LinkCard component that extends the original but accepts and applies custom classes.
Alternatively, you could use more specific CSS selectors to target particular LinkCards based on their content or position in your document.
Let me know if you need more specific guidance!

@hasty stag Another question, to use Code component and import the text from a file, where the file should be ? In public ?
hasty stagBOT
Let me check the knowledge base for you again. One moment! :books:
Based on the knowledge sources, when using the <Code> component to display code from a file, the file doesn't need to be in the public/ directory. Instead, you can import code files directly from anywhere in your project using Vite's ?raw import suffix.
Here's how you can do it:
In MDX files or Astro components, you can import any code file as a string and then pass it to the <Code> component:
import { Code } from '@astrojs/starlight/components';
import importedCode from '/tsconfig.json?raw';
<Code code={importedCode} lang="json" title="tsconfig.json" />
This approach works for any file in your project that you want to display as code. The file can be located anywhere in your project structure that Vite can access.
For files that need to be publicly accessible (like downloadable assets), you would place them in the public/ directory. However, for code that you just want to display on your page using the <Code> component, you can import them directly using the ?raw suffix regardless of their location in your project.
Starlight Code Component documentation provides this example showing how to import and display code from files.

@hasty stag lang="cpp" ou lang="c++" ?
hasty stagBOT
Let me check the knowledge base for you again. One moment! :books:
Based on the knowledge sources provided, both lang="cpp" and lang="c++" are valid options for syntax highlighting C++ code in Astro, though lang="cpp" appears to be the more commonly used format.
When using code blocks in Markdown or the <Code /> component in Astro, you specify the language with the lang attribute. For C++, you can use either:
<Code code={`int main() { return 0; }`} lang="cpp" />
or
<Code code={`int main() { return 0; }`} lang="c++" />
The syntax highlighting in Astro is powered by either Shiki (default) or Prism, both of which support C++ highlighting. Shiki follows the same language identifiers as VS Code, where both "cpp" and "c++" are recognized for C++ code.
If you're using the Prism highlighter component, you would need to check the list of languages supported by Prism for their specific language identifiers, but both options should work there as well.
Is there anything specific about C++ syntax highlighting in Astro that you'd like to know more about?

If I use :
import statcomponentheader from 'statcomponent.h?raw';
I have this error :
Cannot find module 'statcomponent.h?raw' imported from 'E:/Programmes/Documentation/star_doc/src/content/docs/create-component.mdx'
hasty stagBOT
Let me check the knowledge base for you again. One moment! :books:
The error you're encountering is related to how Vite's ?raw import works in Astro. The issue is with the file path in your import statement.
When using the ?raw import suffix to display code with the <Code> component, you need to provide the correct path to your file. The path should be either:
- An absolute path from the root of your project (starting with
/) - A relative path from the current file (starting with
./or../)
Here's how to fix your import:
// If the file is in the same directory as your MDX file
import statcomponentheader from './statcomponent.h?raw';
// OR if it's in a different location (adjust the path accordingly)
import statcomponentheader from '../path/to/statcomponent.h?raw';
// OR with an absolute path from project root
import statcomponentheader from '/src/path/to/statcomponent.h?raw';
According to the Starlight documentation, you can then use this imported code with the <Code> component:
import { Code } from '@astrojs/starlight/components';
import statcomponentheader from './statcomponent.h?raw';
<Code code={statcomponentheader} lang="cpp" title="statcomponent.h" />
This approach works for any code file in your project that Vite can access, as shown in the Starlight Code Component documentation.
Make sure the file exists at the specified path and that you're using the correct relative or absolute path from your MDX file.
If you're still having issues, check that your Astro configuration doesn't have any restrictions on importing files with the .h extension.

@hasty stag Is it possible to display multiple file in one Code ?
hasty stagBOT
Let me check the knowledge base for you again. One moment! :books:
Based on the knowledge sources provided, there isn't specific information about displaying multiple files in a single <Code> component in Astro or Starlight.
The Starlight <Code> component documentation shows how to display code from a single file:
import { Code } from '@astrojs/starlight/components';
import importedCode from '/tsconfig.json?raw';
<Code code={importedCode} lang="json" title="tsconfig.json" />
However, there's no direct mention of a built-in capability to display multiple files in one <Code> component.
If you need to display multiple files, the most straightforward approach would be to use multiple <Code> components, one for each file:
import { Code } from '@astrojs/starlight/components';
import headerFile from './header.h?raw';
import implementationFile from './implementation.cpp?raw';
<Code code={headerFile} lang="cpp" title="header.h" />
<Code code={implementationFile} lang="cpp" title="implementation.cpp" />
Alternatively, you could potentially concatenate the content of multiple files with appropriate separators and headers in your JavaScript code before passing it to a single <Code> component, but this would be a custom solution rather than a built-in feature.
If you're looking for more advanced code display features, you might want to explore the Expressive Code documentation directly, as Starlight's <Code> component is built on Expressive Code.
