global CSS problem | Astro Lounge | Page 1

I wanna override the TableOfContents different on some pages / routes, where different global styling is applied that conflicts with each other:

The override:

---
import Default from '@astrojs/starlight/components/TableOfContents.astro'
import BottomTableOfContentWrapper from 'starlight-cooler-credit/components/BottomTableOfContentWrapper.astro'
import TopTableOfContentWrapper from 'starlight-cooler-credit/components/TopTableOfContentWrapper.astro'
import DefaultBottomTableOfContentWrapper from 'starlight-cooler-credit/components/DefaultBottomTableOfContentWrapper.astro'

const currentPath = Astro.url.pathname;
const showBottomTable = currentPath.includes('bottom-table-of-content-wrapper');
const showTopTable = currentPath.includes('top-table-of-content-wrapper');
---

{showBottomTable ? (
  <Default><slot /></Default>
  <BottomTableOfContentWrapper>
    <p>Hello, Astronaut! 👨‍🚀</p>
  </BottomTableOfContentWrapper>
) : showTopTable ? (
  <TopTableOfContentWrapper>
    <p>✨ Reaching for the stars! ✨</p>
  </TopTableOfContentWrapper>
  <Default><slot /></Default>
) : (
  <Default><slot /></Default>
  <DefaultBottomTableOfContentWrapper />
)}

In BottomTableOfContentWrapper I make the right-sidebar-panel display: flex; and in TopTableOfContentWrapper I make it display: block;

Because Astro is a static site generator, both styles are existing even when not on any of those routes, making the sidebar look wrong...

It's important that the structure of the overrides don't change because it's a Starlight plugin which should only simple stuff.

I can provide the code of the Top/BottomTableOfContentWrappers if you want!

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

To address your global CSS problem with overriding the TableOfContents component in Starlight, we need to consider a few approaches that can help isolate styles for specific routes without affecting others. Based on the information provided in the knowledge sources, here are some suggestions:

Use scoped styles:
Starlight and Astro support scoped styles by default. You can leverage this feature to ensure that styles only apply to specific components. Instead of using global styles in your TableOfContentWrapper components, use scoped styles:

<style>
  :global(.starlight-table-of-contents) {
    /* Your styles here */
  }
</style>

This approach will scope the styles to the specific component, reducing conflicts with other pages CSS & Styling.

Use CSS custom properties:
Instead of directly setting display: flex or display: block, use CSS custom properties (variables) that you can override based on the route:

<style is:global>
  .starlight-table-of-contents {
    display: var(--toc-display, block);
  }
</style>

Then, in your wrapper components, you can set the variable:

<style is:global>
  :root {
    --toc-display: flex; /* or block */
  }
</style>

This approach allows you to change the display property without conflicting styles CSS & Styling.

Use class:list for conditional styling:
Astro provides a class:list utility that can help apply classes conditionally. You can use this in combination with scoped styles to apply different styles based on the route:

#

---
const currentPath = Astro.url.pathname;
const isBottomTable = currentPath.includes('bottom-table-of-content-wrapper');
const isTopTable = currentPath.includes('top-table-of-content-wrapper');
---

<div class:list={['starlight-table-of-contents', { 'bottom-toc': isBottomTable, 'top-toc': isTopTable }]}>
  <slot />
</div>

<style>
  .starlight-table-of-contents {
    /* Default styles */
  }
  .bottom-toc {
    display: flex;
  }
  .top-toc {
    display: block;
  }
</style>

This approach allows you to apply specific styles only when needed Styling in Astro.

Use the is:global directive selectively:
If you need to use global styles, be selective about which styles are global and which are scoped. This can help minimize conflicts:

<style>
  /* Scoped styles */
  .my-component {
    /* ... */
  }
</style>

<style is:global>
  /* Global styles, use sparingly */
  .starlight-table-of-contents {
    /* ... */
  }
</style>

By combining these approaches, you should be able to create route-specific styles for your TableOfContents without affecting other pages. Remember to use global styles judiciously and leverage Astro's scoped styling features as much as possible to avoid conflicts.

@green dune Kapa.ai is still learning and improving, please let me know how I did by reacting below.

@uncut mauve would it also somehow be possible to create a general style that creates "3 boxes" where the different contents can be dynamically put in?

Like can you generate the CSS for me to create a layout like this:

Box 1 (TopWrapper)
ToC

much space (justify: between)

Box 2 (BottomWrapper) - always stuck to bottom

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

#

Based on your request for a layout with three boxes where content can be dynamically placed, I can provide you with a CSS solution that creates this structure. However, it's important to note that the exact implementation might need to be adjusted depending on your specific Astro and Starlight setup.

Here's a CSS example that creates the layout you described:

.layout-container {
  display: flex;
  flex-direction: column;
  min-height: 100vh; /* Full viewport height */
}

.top-wrapper {
  /* Box 1 */
}

.toc-wrapper {
  /* Table of Contents */
}

.content-wrapper {
  flex-grow: 1; /* Takes up remaining space */
}

.bottom-wrapper {
  /* Box 2 - Always stuck to bottom */
}

To use this CSS, you would need to structure your HTML (or Astro components) like this:

<div class="layout-container">
  <div class="top-wrapper">
    <!-- TopWrapper content -->
  </div>
  <div class="toc-wrapper">
    <!-- Table of Contents -->
  </div>
  <div class="content-wrapper">
    <!-- Main content -->
  </div>
  <div class="bottom-wrapper">
    <!-- BottomWrapper content -->
  </div>
</div>

This layout uses flexbox to create a column structure that fills the entire viewport height. The content-wrapper will expand to fill the available space between the top and bottom sections.

To integrate this with your existing Starlight setup, you might need to modify your layout component or create a new one that wraps the default Starlight layout. Here's a general approach:

Create a new layout component, let's call it CustomLayout.astro.
In this component, use the structure provided above.
Place your Starlight components and other content in the appropriate wrappers.

For example:

#

---
import Default from '@astrojs/starlight/components/TableOfContents.astro'
import BottomTableOfContentWrapper from 'starlight-cooler-credit/components/BottomTableOfContentWrapper.astro'
import TopTableOfContentWrapper from 'starlight-cooler-credit/components/TopTableOfContentWrapper.astro'
---

<div class="layout-container">
  <div class="top-wrapper">
    <TopTableOfContentWrapper>
      <p>✨ Reaching for the stars! ✨</p>
    </TopTableOfContentWrapper>
  </div>
  <div class="toc-wrapper">
    <Default><slot /></Default>
  </div>
  <div class="content-wrapper">
    <!-- Main content goes here -->
  </div>
  <div class="bottom-wrapper">
    <BottomTableOfContentWrapper>
      <p>Hello, Astronaut! 👨‍🚀</p>
    </BottomTableOfContentWrapper>
  </div>
</div>

<style>
  .layout-container {
    display: flex;
    flex-direction: column;
    min-height: 100vh;
  }

  .top-wrapper {
    /* Styles for top wrapper */
  }

  .toc-wrapper {
    /* Styles for Table of Contents */
  }

  .content-wrapper {
    flex-grow: 1;
  }

  .bottom-wrapper {
    /* Styles for bottom wrapper */
  }
</style>

Remember to adjust the styles as needed to fit with your existing Starlight theme and to ensure compatibility with Starlight's responsive design.
