# Team Grid Block Design

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Build a new `team-grid` ACF block for the Team page (and any other page that needs a team grid) that renders a responsive grid of team members. Each member shows their photo (rounded rectangle), name, and title. The bio is collapsed by default and expands vertically with a smooth animation when the photo, name, or title is clicked.

**Architecture:** One new ACF block (`acf/team-grid`) with a single repeater of `members` (image, name, title, bio). The block uses native HTML `<details>`/`<summary>` for the click-to-expand interaction, animated with the `grid-template-rows: 0fr → 1fr` CSS pattern (no JavaScript). The block has no built-in background — the editor wraps it in an existing Section block when a dark/light background is needed. The page template is unchanged; the editor adds the block to the Team page in Gutenberg.

**Tech Stack:** WordPress 6.x, PHP 8.x, Tailwind CSS v4, Playwright, axe-core, PHPCS (WordPress standard).

## Global Constraints

- Tabs for PHP indentation (project standard).
- `static/dist/theme.css` is committed (not gitignored) per project convention.
- PHPCS uses the WordPress coding standard; `composer lint` must pass for all touched files.
- All design colors use the project's existing CSS custom properties from `styles/base/colors.css`. No hardcoded hex values for theme colors.
- Reuse existing design tokens where possible (e.g. the `text-cwc-blue-01` heading color, `var(--color-secondary)` accent if needed).
- The headshot uses `rounded-md` to match other image cards in the project (`post-list`, `services-list`).
- All commits follow the project's emoji-prefixed commit-message style (e.g. `✨ feat: …`).
- This work does **not** edit `header.php`, `footer.php`, `views/partials/page-hero.php`, or `views/partials/page-hero-services.php`.
- `page.php` is not modified.
- No JavaScript files are added. The `<details>`/`<summary>` interaction is fully native.
- Reuse the same `regACFBlocks()` auto-registration pattern as `services-list`.

## Reference Mockup

`team-example.png` shows a dark-blue section with 8 team members in a 2-column grid. Each member has a circular headshot, name (bold), title (italic), and a multi-line bio below. All bios are visible in the mockup.

**Intent of the design (per the user):**
- The bio should be a `<details>` element that **opens vertically** when the photo, name, or title is clicked. The mockup shows the open state for every member for context; the live behavior is collapsed by default.
- The headshot should be a **rectangle with rounded corners that match other images in the project** — `rounded-md` is the project standard. The mockup's circular headshots are a visual approximation; the live design uses rounded rectangles.
- The block has no built-in background. The editor wraps it in a Section block (`acf/section`) when a dark or light background is needed.
- Layout is responsive: 1 column on mobile, 2 on tablet, 3 on desktop (the user's "3-2-1" choice).

## Design Details

### 1. ACF field group: `acf/team-grid`

**Block name (registration key):** `acf/team-grid`
**Editor title:** "Team Grid"
**Category:** common
**Description (in block.json):** "A responsive grid of team members. Click a card to expand the bio."

#### ACF field group (`acf/group_team_grid.json`)

```
Group key:    group_team_grid
Group title:  Team Grid
Position:     normal
Menu order:   0
Location:     block == acf/team-grid
```

Fields:
- `members` (repeater, layout: block, button label: "Add Team Member")
  - `image` (image, return_format: array, required: 0) — Headshot.
  - `name` (text, required: 0) — Person's name (e.g. "Christopher Werner").
  - `title` (text, required: 0) — Person's role (e.g. "Principal Consultant & CEO").
  - `bio` (wysiwyg, tabs: visual, toolbar: basic, media_upload: 0, required: 0) — Bio body copy.

The block is intentionally minimal. No per-card size, no global layout toggle, no CTA field, no group-level background color. Layout derives from CSS (`grid-cols-1 sm:grid-cols-2 lg:grid-cols-3`).

#### Block registration (`views/blocks/team-grid/block.json`)

```json
{
    "name": "acf/team-grid",
    "title": "Team Grid",
    "description": "A responsive grid of team members. Click a card to expand the bio.",
    "category": "common",
    "icon": "groups",
    "keywords": ["team", "people", "staff", "bio"],
    "acf": {
        "mode": "preview",
        "renderTemplate": "team-grid.php"
    },
    "supports": {
        "anchor": true,
        "align": false
    }
}
```

The `icon: "groups"` is a WordPress Dashicon that visually represents a group of people.

#### Block template (`views/blocks/team-grid/team-grid.php`)

```php
<?php
/**
 * Block Name: Team Grid
 *
 * A responsive grid of team members. Each card uses a native <details>
 * element so the bio expands when the photo, name, or title is clicked.
 *
 * @package CWC
 */

namespace CWC;

$members = get_field( 'members' );

if ( empty( $members ) ) {
    return;
}

$classes  = 'team-grid container my-section mx-auto';
$wrapper  = blockWrapperAttributes( $classes, $is_preview );
?>

<section <?php echo wp_kses_post( $wrapper ); ?>>
    <div class="team-grid__inner grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-3 gap-8 lg:gap-12">
        <?php foreach ( $members as $member ) : ?>
            <article class="team-grid__card">
                <details class="team-grid__details">
                    <summary class="team-grid__summary">
                        <?php if ( ! empty( $member['image'] ) ) : ?>
                            <img
                                class="team-grid__photo"
                                src="<?php echo esc_url( $member['image']['url'] ); ?>"
                                alt="<?php echo esc_attr( $member['image']['alt'] ?? '' ); ?>"
                                loading="lazy"
                            />
                        <?php endif; ?>

                        <?php if ( ! empty( $member['name'] ) ) : ?>
                            <h3 class="team-grid__name">
                                <?php echo wp_kses_post( $member['name'] ); ?>
                            </h3>
                        <?php endif; ?>

                        <?php if ( ! empty( $member['title'] ) ) : ?>
                            <p class="team-grid__title">
                                <?php echo wp_kses_post( $member['title'] ); ?>
                            </p>
                        <?php endif; ?>
                    </summary>

                    <div class="team-grid__bio-wrap">
                        <div class="team-grid__bio-inner">
                            <?php if ( ! empty( $member['bio'] ) ) : ?>
                                <div class="team-grid__bio">
                                    <?php echo wp_kses_post( $member['bio'] ); ?>
                                </div>
                            <?php endif; ?>
                        </div>
                    </div>
                </details>
            </article>
        <?php endforeach; ?>
    </div>
</section>
```

Notes:
- Native `<details>`/`<summary>`: the summary is the click target (photo + name + title); the body is the bio wrap.
- The `<details>` element is closed by default — no `open` attribute. The user opens it on click.
- The bio uses `wysiwyg` so editors can add links or basic formatting. Output is sanitized via `wp_kses_post`.
- `team-grid__bio-wrap` is a 1-row grid container that animates `grid-template-rows` from `0fr` to `1fr`. The `__bio-inner` inside has `overflow: hidden; min-height: 0` so the bio is clipped during the transition.

#### Block styles (`views/blocks/team-grid/team-grid.css`)

```css
/* Team Grid block */

.team-grid {
    &__card {
        @apply flex flex-col;
    }

    &__details {
        @apply flex flex-col;
    }

    /* summary is the click target. Strip the default disclosure triangle. */
    &__summary {
        @apply flex flex-col items-center text-center cursor-pointer list-none;

        &::-webkit-details-marker {
            display: none;
        }

        &::marker {
            display: none;
            content: '';
        }
    }

    &__photo {
        @apply w-32 h-32 sm:w-40 sm:h-40 lg:w-48 lg:h-48 object-cover rounded-md mb-4;
    }

    &__name {
        @apply text-cwc-blue-01 text-22px font-bold leading-tight mb-1;
    }

    &__title {
        @apply text-gray-600 text-16px font-light italic mb-3;
    }

    /* Animation: animate grid-template-rows 0fr -> 1fr. */
    &__bio-wrap {
        display: grid;
        grid-template-rows: 0fr;
        transition: grid-template-rows 300ms ease;
    }

    &__details[open] &__bio-wrap {
        grid-template-rows: 1fr;
    }

    &__bio-inner {
        overflow: hidden;
        min-height: 0;
    }

    &__bio {
        @apply text-gray-700 text-16px font-light leading-snug pt-2;
    }
}
```

Notes:
- The summary is a flex column with `items-center` so the photo, name, and title stack centered. This matches the mockup.
- The default `<summary>` marker (▶ triangle) is hidden with `list-style: none` plus vendor-prefixed `::-webkit-details-marker` and `::marker` reset.
- The `&__details[open] &__bio-wrap` selector uses CSS nesting to target the bio wrap when the parent details is open. This compiles to `.team-grid__details[open] .team-grid__bio-wrap { grid-template-rows: 1fr; }`.
- The `team-grid__details[open] &__bio-wrap` syntax uses CSS nesting: `&` inside `&__details[open]` is the previous compound selector. Tailwind v4 (lightningcss) unwraps this correctly.
- Photo sizes: `w-32 h-32` (8rem / 128px) on mobile, `w-40 h-40` (10rem / 160px) on small, `w-48 h-48` (12rem / 192px) on large.

### 2. CSS import wiring (`styles/blocks/index.css`)

Append at the end of `styles/blocks/index.css`:

```css
@import '../../views/blocks/team-grid/team-grid.css';
```

After the edit, the file ends with:

```
@import '../../views/blocks/services-list/services-list.css';
@import '../../views/blocks/team-grid/team-grid.css';
```

### 3. Page integration

`page.php` is unchanged. The editor adds a `Team Grid` block to the Team page (`/team/`) in Gutenberg. To get the dark-blue background, the editor wraps the `Team Grid` block in a `Section` block (`acf/section`) and sets the Section's `background_color` to the dark blue.

No PHP template change is required.

### 4. CSS Build

Run `npm run build` to compile Tailwind v4 → `static/dist/theme.css`. The new utilities (e.g. `text-22px`, `text-16px`, `w-32 h-32`, `rounded-md`) must appear in the dist.

### 5. Tests (`tests/team-page.spec.js`)

```js
import { test, expect } from "@playwright/test";
import AxeBuilder from "@axe-core/playwright";

test.describe("Team Grid block on /team/", () => {
    test("renders the photo, name, and title for each member", async ({ page }) => {
        await page.goto("/team/");

        const cards = page.locator(".team-grid__card");
        await expect(cards.first()).toBeVisible();

        const firstCard = cards.first();
        await expect(firstCard.locator(".team-grid__photo")).toBeVisible();
        await expect(firstCard.locator(".team-grid__name")).toBeVisible();
        await expect(firstCard.locator(".team-grid__title")).toBeVisible();
    });

    test("bio is hidden by default and expands on summary click", async ({ page }) => {
        await page.goto("/team/");

        const firstDetails = page.locator(".team-grid__details").first();
        // Bio is closed by default.
        await expect(firstDetails).not.toHaveAttribute("open", "");

        // Click the summary; the details should open and the bio should be visible.
        await firstDetails.locator(".team-grid__summary").click();
        await expect(firstDetails).toHaveAttribute("open", "");
        await expect(firstDetails.locator(".team-grid__bio")).toBeVisible();

        // Click again; the details should close.
        await firstDetails.locator(".team-grid__summary").click();
        await expect(firstDetails).not.toHaveAttribute("open", "");
    });

    test("no axe violations on the team-grid block", async ({ page }) => {
        await page.goto("/team/");
        const results = await new AxeBuilder({ page })
            .include(".team-grid")
            .analyze();
        expect(results.violations).toEqual([]);
    });
});
```

### Out of Scope

- The Team page template — `page.php` is unchanged. The editor adds the block in Gutenberg.
- The Section block wrapper for the dark-blue background — the editor composes this in Gutenberg.
- A custom open/close icon or arrow indicator — the click target is the entire summary (photo + name + title), so no chevron is needed.
- Animations beyond the bio's expand/collapse transition. No hover transforms, no entry animations.
- Per-card size variants — all cards are the same size.
- A `data-team-member-id` slug for deep-linking to a specific member's expanded bio.
- Dark-mode overrides — the block is color-agnostic and inherits the parent Section's color scheme.
- Per-page header/footer changes.

## Self-Review Notes

- **Spec coverage:** One new ACF block (4 files), one CSS import, dist rebuild, one test file. Every spec section is covered.
- **Placeholder scan:** No TBDs. Every step has a concrete file path, exact content, exact command, and expected output.
- **Type consistency:** Class names use the existing BEM convention (`__card`, `__details`, `__summary`, `__photo`, `__name`, `__title`, `__bio-wrap`, `__bio-inner`, `__bio`). Field names (`members`, `image`, `name`, `title`, `bio`) are used in the JSON, the PHP, and the tests.
- **Scope check:** Single focused build, no decomposition needed. Block is small (≤4 files), testable in isolation, and composable on the Team page (and any other page that needs a team grid).
- **Ambiguity check:** The "rounded rectangle" headshot is concretely specified as `rounded-md`. The "open vertically" animation is concretely specified as `grid-template-rows: 0fr → 1fr` with a 300ms transition. The "3-2-1" responsive grid is concretely specified. The "no background" decision is concretely scoped to the Section block wrapper (editor's responsibility, not this block's).
