Advanced Styling

Where styling lives as of SDK v3.2+. Colors, borders, layout, and shadows are driven by CSS custom properties — not by HTML attributes. These variables can be set two ways:

From the Settings API (preferred) — theming is configured per-tenant in the Bonsai dashboard and injected into the component’s shadow DOM automatically at load time.
From your page’s CSS — override any variable on the <bonsai-search> host element (or its container) to customize per-embed. Page CSS wins over the Settings API because Settings-API variables are injected at :host low specificity.

Legacy HTML attributes like brand-color, text-color, input-bg, card-bg, etc. are no longer supported — use the variables on this page instead.

Outer Container

If you want to customize the layout and positioning, wrap the component in a container and add custom CSS.

Example:

<style>
  .bonsai-search-outer-container {
    width: 100%;
    max-width: 42rem;
    margin: 4rem auto;
    min-height: 350px;
  }

  bonsai-search {
    --bonsai-brand-color: #0A5B3B;
    --bonsai-text-color: #303030;
    --bonsai-muted-color: #9CA3AF;
  }
</style>

<div class="bonsai-search-outer-container">
  <bonsai-search
    api-key="API-KEY"
    base-url="https://api.hibonsai.com/rest/search/v3/"
  ></bonsai-search>
</div>

CSS Variables

The web component uses a closed shadow root, but CSS custom properties still pass through. You can set any --bonsai-* variables directly on the <bonsai-search> element if you prefer CSS-only customization.

Example:

<bonsai-search
  style="
    --bonsai-font-body: 'Space Grotesk', sans-serif;
    --bonsai-font-heading: 'Space Grotesk', sans-serif;
    --bonsai-font-mono: 'IBM Plex Mono', monospace;
    --bonsai-search-max-width: 100%;
    --bonsai-text-color: #111111;
    --bonsai-muted-color: #6b7280;
    --bonsai-input-bg: #ffffff;
    --bonsai-input-text-color: #111111;
    --bonsai-suggestions-text-color: #111111;
    --bonsai-suggestions-hover-bg: rgba(0, 0, 0, 0.06);
    --bonsai-results-text-color: #eaeaea;
    --bonsai-card-text-color: #111111;
  "
  api-key="API-KEY"
  base-url="https://api.hibonsai.com/rest/search/v3/"
  theme="dark"
></bonsai-search>

Defaults shown are for the light theme. The dark theme automatically overrides color and shadow variables.

Shadow Parts

The web component uses a closed shadow root, but it exposes stable part hooks for external styling. This lets you style specific inner elements with ::part(...) from outside the component. ::part(...) is supported in modern evergreen browsers. For older browsers, prefer CSS variables or wrapper styling. Example (full part customization):

<style>
  bonsai-search::part(search-wrapper) {
    padding: 1.5rem;
    border: 1px solid #262626;
    border-radius: 18px;

Customization Tips

Theme Defaults vs. Overrides

theme="light" (default) and theme="dark" set a full palette of sensible defaults for surfaces, borders, shadows, and text. Any CSS custom properties you set (like --bonsai-text-color, --bonsai-input-bg, or --bonsai-card-bg) override those defaults. theme="auto" uses the visitor’s system preference (prefers-color-scheme) and still respects any explicit overrides.

Where styling values come from

Precedence, highest to lowest:

Your page CSS — any --bonsai-* variable set on the <bonsai-search> host element, on an ancestor, or in a :root rule.
Settings API — values configured per-tenant from the Bonsai dashboard; the component injects a low-specificity :host { ... } block of CSS variables into its shadow DOM at load time.
Built-in theme defaults — the palette for the active theme (light / dark / auto).

Set defaults once in the Settings API to theme all embeds for a tenant; only write page CSS when you need to override a specific embed.

Wrapper Styling

The example includes a wrapper <div> with custom CSS to control the component’s width and positioning. You can modify these styles to match your site’s layout:

.bonsai-search-outer-container {
  width: 100%;
  max-width: 42rem; /* Adjust maximum width */
  margin: 4rem auto; /* Adjust vertical and horizontal spacing */
  min-height: 350px; /* Ensure minimum height for layout stability */
}

Color Scheme

Choose colors that match your brand identity. The component uses your specified colors throughout the interface:

--bonsai-brand-color: Used for primary actions and highlights
--bonsai-text-color: Used for main content text
--bonsai-muted-color: Used for secondary information
Background colors: Control the overall appearance
- --bonsai-input-bg affects the input and the dropdown background
- --bonsai-card-bg affects result cards
- --bonsai-surface-color and --bonsai-canvas-color control larger surfaces
