How would i put a glowing effect on an image without editing the image itself? Would be simple css but the problem is that the image is in the page header which makes it quite hard to edit.

Hi @harsh hamlet. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To add a glowing effect to an image in your Astro (or Starlight) site without editing the image itself, you can use custom CSS. Even if the image is in the page header and not directly editable, you can target it with CSS selectors.

For Starlight sites, you can add a custom CSS file (e.g., src/styles/custom.css) and include it in your astro.config.mjs using the customCss option. For example:

/* src/styles/custom.css */
.header img {
  box-shadow: 0 0 20px 5px #00ffea, 0 0 40px 10px #00ffea;
}

You may need to adjust the selector (.header img) to match the actual structure of your header. The box-shadow property creates a glowing effect around the image.

To apply this CSS in Starlight, add your CSS file to the customCss array in your config:

import { defineConfig } from 'astro/config';
import starlight from '@astrojs/starlight';

export default defineConfig({
  integrations: [
    starlight({
      customCss: ['./src/styles/custom.css'],
    }),
  ],
});

If you want to target the logo specifically, inspect the header in your browser to find the correct selector for the image element.

If you need to use cascade layers for more precise control, you can use the @layer rule as described in the Starlight documentation.

There is no direct mention of a "glow" effect in the knowledge sources, but the above method uses standard CSS, which is supported for customizing Starlight and Astro sites. If you need more specific targeting, you may need to inspect your site's HTML structure to find the right selector.

@sturdy shale how to make icon in hero glow?

Let me check the knowledge base for you again. One moment! :books:

To make the icon in a Starlight hero section "glow," you would need to apply a CSS effect (such as a box-shadow) to the icon. However, the knowledge sources do not provide a direct example of adding a glowing effect specifically to the hero icon.

What is documented is that you can customize Starlight’s styles by adding a custom CSS file and referencing it in your Starlight configuration. You can target the icon in the hero section using a CSS selector, but you will need to inspect your site to determine the exact selector for the icon in the hero.

Here’s how you would generally approach it:

  1. Add a custom CSS file (e.g., src/styles/custom.css) with a rule targeting the hero icon. For example:

    /* Adjust the selector to match your hero icon */
.sl-hero [data-icon] {
  box-shadow: 0 0 16px 4px #00ffea, 0 0 32px 8px #00ffea;
}

  2. Reference your CSS file in your Starlight config:

    import { defineConfig } from 'astro/config';
import starlight from '@astrojs/starlight';

export default defineConfig({
  integrations: [
    starlight({
      customCss: ['./src/styles/custom.css'],
    }),
  ],
});

  3. Adjust the selector as needed to match the actual icon element in your hero. You may need to inspect the rendered HTML to find the correct class or attribute.

The knowledge sources do not provide a built-in "glow" option for hero icons, so this approach uses standard CSS customization, which is supported by Starlight. If you need more precise targeting, inspect your site’s HTML to find the right selector.
