Grail Layout Bottom Footer

GrailLayoutBottomFooter is a headless container for the bottom footer section of a GrailLayout. It spans the full width of the layout and typically contains copyright, links, or site-wide footer content.

Example

Footer

<footer class="grail-layout-bottom-footer">Footer</footer>
Usage example 
<script lang="ts">
    import GrailLayoutBottomFooter from "./GrailLayoutBottomFooter.svelte";
</script>

<GrailLayoutBottomFooter>
    <footer><small>Copyright 2026</small></footer>
</GrailLayoutBottomFooter>
Show Svelte source 
// In your Svelte component:
import GrailLayoutBottomFooter from "lily-design-system-svelte-headless/components/GrailLayoutBottomFooter/GrailLayoutBottomFooter.svelte";

<GrailLayoutBottomFooter>
  <!-- content -->
</GrailLayoutBottomFooter>

Usage

<GrailLayout>
  <GrailLayoutTopHeader>...</GrailLayoutTopHeader>
  <GrailLayoutLeftAside>...</GrailLayoutLeftAside>
  <GrailLayoutCenterMain>...</GrailLayoutCenterMain>
  <GrailLayoutRightAside>...</GrailLayoutRightAside>
  <GrailLayoutBottomFooter>
    <Footer />
  </GrailLayoutBottomFooter>
</GrailLayout>

Props

  • children: slot (required) -- content to render inside the bottom footer section
  • ...restProps: unknown -- additional attributes spread onto the <div> element

When to Use

  • Use inside GrailLayout as the full-width bottom footer area.
  • Use to contain copyright notices, site-wide links, or legal information.
  • Use when the page layout requires a persistent footer spanning the full width below the sidebar and main content.

When Not to Use

  • Do not use outside GrailLayout -- use Footer for standalone page footers.
  • Do not use for inline content summaries -- use a Panel or Card instead.

Keyboard Interactions

  • No keyboard interactions — this is a passive landmark container
  • Focusable descendants follow native tab order

ARIA

  • Native <footer> exposes a contentinfo landmark when used as the top-level page footer so screen readers can navigate to it via landmark navigation
  • Implicit contentinfo role from the <footer> element when used as a top-level landmark

Headless

This headless component renders semantic HTML. The consumer provides all visual styling — no CSS, animations, or layout assumptions are baked in.

Styles

The consumer provides all CSS styling. The component renders with a .grail-layout-bottom-footer class for targeting. No default styles are included — this is a fully headless component.

Testing

  • Verify the component renders a <footer> element with class grail-layout-bottom-footer
  • Verify pass-through attributes are applied

Composition

GrailLayoutBottomFooter is used as a child of GrailLayout. Place a semantic <footer> element inside for proper accessibility.
