Starlight <a> text color being overridden by browser

[pine pelican]

Using starlight template, the text in <a> should be of accent color, but it is always blue (overridden to default link text color by the browser). How to solve it?

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

If your Starlight site’s <a> (anchor) text color is always blue and not using your theme’s accent color, it’s likely that the browser’s default link styles are taking precedence over Starlight’s intended styles. This can happen if the relevant CSS is missing, not loaded, or overridden.

How to solve it:

1. Check that Starlight’s CSS is loaded:
   Starlight uses CSS custom properties (variables) to set accent colors for links. If you’re using custom CSS, make sure it’s included correctly in your astro.config.mjs under the customCss option, and that it does not unintentionally override or omit the accent color variables. For example:

   import { defineConfig } from 'astro/config';
   import starlight from '@astrojs/starlight';
   
   export default defineConfig({
     integrations: [
       starlight({
         customCss: ['./src/styles/custom.css'],
       }),
     ],
   });
   

   Custom CSS styles

2. Ensure CSS custom properties for accent colors are set:
   Starlight uses variables like --color-accent-500 for link colors. If you override these, make sure they are set to your desired color in your CSS:

   :root {
     --color-accent-500: #yourAccentColor;
   }
   

   Theming

3. Check CSS specificity and cascade order:
   If you add your own CSS, ensure it does not unintentionally override Starlight’s link styles. Starlight uses cascade layers to manage style order. Unlayered custom CSS will override Starlight’s defaults. If you want your custom styles to be applied after Starlight’s, use the @layer directive:

   @layer my-overrides {
     a {
       color: var(--color-accent-500);
     }
   }

Cascade layers

4. If using Tailwind, check your theme config:
   Starlight will use values from your Tailwind theme config for accent colors if you’re using the Starlight Tailwind plugin. Make sure your Tailwind config or CSS variables are set up as described in the docs.

Summary:
Make sure Starlight’s CSS is loaded, the accent color variables are set, and your custom CSS does not override link styles unintentionally. Adjust the cascade order if needed to ensure Starlight’s link styles take effect.

@wild plover The color is set correctly. However, through the dev window in browser it seems that the color is being overridden by User agent stylesheet, which defines a default blue color for anchors. How do I solve it?

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

If the browser’s user agent stylesheet is overriding your Starlight link color, it means your custom or Starlight CSS is not being applied with sufficient specificity or is not loaded after the user agent styles.

How to solve it:

• Ensure your custom CSS is loaded and included in the Starlight customCss array in your astro.config.mjs. This ensures your styles are loaded after the user agent stylesheet and can override it. For example:

  import { defineConfig } from 'astro/config';
  import starlight from '@astrojs/starlight';
  
  export default defineConfig({
    integrations: [
      starlight({
        customCss: ['./src/styles/custom.css'],
      }),
    ],
  });
  

  Custom CSS styles

• Increase CSS specificity or use cascade layers. Starlight uses cascade layers, and any unlayered custom CSS will override the default Starlight styles. You can also use the @layer directive to control the order:

  @layer my-overrides {
    a {
      color: var(--color-accent-500);
    }
  }
  

  Cascade layers

• Verify that the CSS variable is set and used. Starlight uses --color-accent-500 for link colors. Make sure this variable is set in your CSS and that your anchor tags use it:

  :root {
    --color-accent-500: #yourAccentColor;
  }
  a {
    color: var(--color-accent-500);
  }
  

  Theming

If you follow these steps, your link color should override the browser’s default blue. If it still does not, double-check that your CSS is not being overridden by another rule with higher specificity or later in the cascade.
