# FeatureTwoColumn Pattern

A feature section pattern that pairs editorial content with a media element in a two-column layout. Designed for showcasing features, products, or use cases with a uniform tertiary link treatment.

## Overview

FeatureTwoColumn supports four color theme variants (neutral, lilac, yellow, green) and adapts responsively across desktop, tablet, and mobile breakpoints. Links always render as tertiary buttons; only their layout adjusts to the number provided.

Layout is implemented as a **single flex structure** (no separate mobile/desktop markup): **below the desktop breakpoint, media always appears above content** so stacked sections read consistently as media → content → media → content. The **`arrange` prop only affects desktop** (≥992px), where it alternates content left vs. content right.

## When to Use

- Highlighting a specific feature, product, or use case
- Presenting content with supporting visual media
- Creating visual variety with alternating left/right arrangements **on desktop**
- When 1-5 action links are needed as a uniform set of text links (no primary/secondary hierarchy)

## Props

| Prop | Type | Default | Description |
|------|------|---------|-------------|
| `color` | `'neutral' \| 'lilac' \| 'yellow' \| 'green'` | `'neutral'` | Background color theme variant |
| `arrange` | `'left' \| 'right'` | `'left'` | **Desktop only:** content column on the left (`left`) or right (`right`). Below desktop, layout is always media on top, then content. |
| `title` | `string` | *required* | Feature title text (heading-md typography) |
| `description` | `string` | *required* | Feature description text (body-l typography) |
| `links` | `FeatureTwoColumnLink[]` | *required* | Array of 1-5 links, all rendered as tertiary buttons (see button behavior below) |
| `media` | `{ src: string; alt: string }` | *required* | Feature media (image) configuration |
| `className` | `string` | - | Additional CSS classes |

### FeatureTwoColumnLink

| Property | Type | Description |
|----------|------|-------------|
| `label` | `string` | Link label text |
| `href` | `string` | Link URL |

## Button Behavior

The component renders a `ButtonGroup` from the links you pass.

**Every link renders as a tertiary button, regardless of count.** This section
pairs its links with editorial copy, so the design calls for one uniform
text-link treatment rather than `ButtonGroup`'s default count-based mix. It's
implemented by passing `forceVariant="tertiary"` and `forceNoPadding`, so the
buttons also sit flush with the title and description instead of being indented
by the button's horizontal padding.

Only the layout still varies with the count:

| Link Count | Layout |
|------------|--------|
| 1-2 links | Inline (stacks on mobile, row at md+), 16px gap / 24px at lg+ |
| 3-5 links | Vertical block layout on all screen sizes (per `ButtonGroup` rules) |

## Variants

### Color Themes

Background tokens are defined in `FeatureTwoColumn.scss` (`$bds-feature-variants`). At a glance:

- **Neutral**: Light neutral background (dark mode uses a slightly darker neutral)
- **Lilac**, **Yellow**, **Green**: Theme-colored backgrounds (light/dark pairs in SCSS)

### Arrangement (`arrange`)

- **`left` (default, desktop):** Content column on the left, media on the right (50% / 50% row).
- **`right` (desktop):** Media on the left, content on the right (`flex-direction: row-reverse` at ≥992px).
- **Mobile and tablet:** `arrange` does not change stacking; **media is always on top**, then content, so repeated sections keep the same vertical rhythm.

## Basic Usage

```tsx
import { FeatureTwoColumn } from 'shared/sections/FeatureTwoColumn';

function MyPage() {
  return (
    <FeatureTwoColumn
      color="lilac"
      arrange="left"
      title="Institutions"
      description="Banks, asset managers, PSPs, and fintechs use XRPL to build financial products and DeFi solutions efficiently and with more flexibility."
      links={[
        { label: "Get Started", href: "/docs" },
        { label: "Learn More", href: "/about" }
      ]}
      media={{ src: "/img/institutions.png", alt: "Institutions illustration" }}
    />
  );
}
```

## Examples

### Single Link

```tsx
<FeatureTwoColumn
  color="green"
  arrange="right"
  title="Developers"
  description="Build powerful applications on XRPL with comprehensive documentation and tools."
  links={[{ label: "View Documentation", href: "/docs" }]}
  media={{ src: "/img/dev.png", alt: "Developer tools" }}
/>
```

### Two Links (inline)

```tsx
<FeatureTwoColumn
  color="yellow"
  arrange="left"
  title="Enterprise Solutions"
  description="Scale your business with blockchain technology."
  links={[
    { label: "Contact Sales", href: "/contact" },
    { label: "Learn More", href: "/enterprise" }
  ]}
  media={{ src: "/img/enterprise.png", alt: "Enterprise" }}
/>
```

### Multiple Links (3-5, block layout)

```tsx
<FeatureTwoColumn
  color="neutral"
  arrange="left"
  title="Explore XRPL"
  description="Discover all the ways to interact with the XRP Ledger."
  links={[
    { label: "Documentation", href: "/docs" },
    { label: "Tutorials", href: "/tutorials" },
    { label: "API Reference", href: "/api" },
    { label: "Community", href: "/community" },
    { label: "GitHub", href: "/github" }
  ]}
  media={{ src: "/img/explore.png", alt: "Explore XRPL" }}
/>
```

## Responsive Behavior

Implementation details live in `FeatureTwoColumn.scss`. Summary:

### Desktop (≥992px)

- **Layout:** One row, two equal-width columns (`width: 50%` each), square (`1:1`) media column.
- **`arrange`:** `left` = content | media; `right` = media | content.
- **Content column:** Internal CSS grid (6 tracks) offsets the text block; vertical padding 96px.
- **Media:** `<img>` with `object-fit: cover` filling the media column (no separate background-image layout).

### Tablet (576px - 991px)

- **Layout:** Stacked column; **media on top**, content below (`flex-direction: column-reverse` on the layout wrapper).
- **Media:** 16:9 aspect ratio.
- **Content column:** Vertical padding 80px; inner grid uses 8 columns with inset content span.

### Mobile (<576px)

- **Layout:** Same stacking as tablet — **media on top**, then content.
- **Media:** 1:1 aspect ratio.
- **Content column:** Vertical padding 64px; inner grid uses 4 columns (full-width content span).

## Accessibility

- Uses semantic `<section>` for the pattern container.
- Title uses `<h2>` for document outline.
- Media uses a real `<img>` with required `alt` text.
- Buttons inherit accessible behavior from the `Button` / `ButtonGroup` components.
- **Note:** On viewports below desktop, **visual order** is media then content, but **DOM order** remains content subtree first, then media. Keyboard and screen-reader order follow the DOM; if reading order must match the visual stack, consider page-level structure or future enhancements.
