<PageFrame>

The <PageFrame> component is an override of Starlight’s <PageFrame>, which has been extended to create a new mobile bar on top of the page, which contains the mobile table of contents (TOC), among other things.

Originally, the <PageFrame> component is used to render the left sidebar, page header and main content.

Usage

Overriding

If you want to extend the <PageFrame> component for your own website, you can do so by creating your own override as seen below.

Note that including the <style> tag is important, as none of the default styles are otherwise included.

1. Create your own PageFrame.astro component in the src/overrides directory (or src/components if you prefer).

   ---
   import MobileMenuToggle from 'virtual:starlight/components/MobileMenuToggle';
   import MobileTableOfContents from 'virtual:starlight/components/MobileTableOfContents';
   import SiteTitle from 'virtual:starlight/components/SiteTitle';
   
   import type { Props } from '../props';
   
   const { hasSidebar } = Astro.props;
   ---
   
   <div class="page sl-flex">
     {
       hasSidebar ? (
         <nav class="sidebar" aria-label={Astro.locals.t('sidebarNav.accessibleLabel')}>
           <div id="starlight__sidebar" class="sidebar-pane">
             <div class="sidebar-content sl-flex">
               <slot name="sidebar" />
             </div>
           </div>
         </nav>
       ) : (<header class="header"><slot name="header" /></header>)
     }
     <div class="main-frame">
       {hasSidebar && (
         <div class="mobile-header">
           <div class="title-wrapper ">
             <SiteTitle {...Astro.props} />
           </div>
           <MobileTableOfContents {...Astro.props} />
           <MobileMenuToggle {...Astro.props} />
         </div>
       )}
       <slot />
     </div>
   </div>
   
   <style>
   .page {
     flex-direction: column;
     min-height: 100vh;
   }
   
   .header {
     z-index: var(--sl-z-index-navbar);
     position: fixed;
     inset-inline-start: 0;
     inset-block-start: 0;
     width: 100%;
     height: var(--sl-nav-height);
     border-bottom: 1px solid var(--sl-color-hairline-shade);
     padding: var(--sl-nav-pad-y) var(--sl-nav-pad-x);
     padding-inline-end: var(--sl-nav-pad-x);
     background-color: var(--sl-color-bg-nav);
   }
   
   :global([data-has-sidebar]) .header {
     padding-inline-end: calc(var(--sl-nav-gap) + var(--sl-nav-pad-x) + var(--sl-menu-button-size));
   }
   
   .sidebar-pane {
     visibility: var(--sl-sidebar-visibility, hidden);
     position: fixed;
     z-index: var(--sl-z-index-menu);
     inset-block: var(--sl-nav-height) 0;
     inset-inline-start: 0;
     width: 100%;
     background-color: var(--sl-color-black);
     overflow-y: auto;
   }
   
   :global([aria-expanded='true']) ~ .sidebar-pane {
     --sl-sidebar-visibility: visible;
   }
   
   .sidebar-content {
     height: 100%;
     min-height: max-content;
     padding: 1rem var(--sl-sidebar-pad-x) 0;
     flex-direction: column;
     gap: 1rem;
   }
   
   @media (min-width: 50rem) {
     .sidebar-content::after {
       content: '';
       padding-bottom: 1px;
     }
   }
   
   .main-frame {
     padding-top: calc(var(--sl-nav-height) + var(--sl-mobile-toc-height));
     padding-inline-start: var(--sl-content-inline-start);
   }
   
   @media (min-width: 50rem) {
     :global([data-has-sidebar]) .header {
       padding-inline-end: var(--sl-nav-pad-x);
     }
     .sidebar-pane {
       --sl-sidebar-visibility: visible;
       width: var(--sl-sidebar-width);
       background-color: var(--sl-color-bg-sidebar);
       border-inline-end: 1px solid var(--sl-color-hairline-shade);
     }
   }
   </style>

2. Add the override to your astro.config.mjs file.

   astro.config.mjs

   import starlight from '@astrojs/starlight';
   import { defineConfig } from 'astro/config';
   
   export default defineConfig({
     integrations: [
       starlight({
         title: 'My Docs',
         components: {
           // Override the theme's `PageFrame` component.
           PageFrame: './src/overrides/PageFrame.astro'
         },
       }),
     ],
   })
