Linking css file with svelte component

The Problem:

I am trying to connect a CSS file to my Svelte component. I tried utilizing a link element to establish the connection, but it was unsuccessful. While defining the styles inline, they are applied to the component, but when I attempt to link the component with a CSS file, it fails, and the styles are not applied. How can I successfully link my Svelte component to an external CSS file?

The Solutions:

Solution 1: Using @import directive

To import styles into a Svelte component, use the CSS `@import` directive with the file name on it. For example:

“`svelte
<h1>This is a title</h1>
<p>More content</p>
<style>
@import './styles.css';
</style>
“`

This approach is useful if you want to reuse some CSS for different components. However, it’s generally recommended to isolate styles into their own components or use the `+layout.svelte` file.

Solution 2: Linking CSS File to Svelte Component

Svelte prefers encapsulated styles within the component itself. However, if you wish to link an external CSS file globally, follow these steps:

In the root HTML file (src/app.html for SvelteKit):

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <link rel="stylesheet" href="/style/index.css">
  <!-- ... other head elements ... -->
</head>
<body>
  <script type="module" src="/build/bundle.js"></script>
</body>
</html>

Considerations:

Ensure the path to the CSS file is correct.
Verify that the CSS file is being served.
Check for caching issues (try a hard reload or incognito browsing).
