# Beautify “Connect to Device” Popup (Tauri + HTML)

## Goal

Redesign the **Connect to Device** popup/modal to match the app’s **glassmorphism + neon purple** style:

* Frosted glass modal
* Blurred/dimmed overlay background
* Clean device list with hover + selected states
* Premium rounded corners and soft glow
* Works smoothly inside **Tauri WebView** (desktop)

---

## Requirements

### Functional

* Modal opens/closes via existing app logic (do not change behavior).
* Device list supports:

  * Hover highlight
  * Single selected device (one at a time)
  * Click selects device (and triggers existing handler)
* “Cancel” button closes modal (existing handler).
* Include “This Computer (Local Playback)” option at top.

### Visual

* Overlay blur + dark tint behind modal.
* Modal background: semi-transparent glass with blur.
* No harsh borders; use subtle border + soft shadow.
* Selected device: gradient accent + glow.
* Smooth animation on open (scale + fade).
* Desktop-friendly sizing (320–420px wide).

### Tauri Safety / Performance

* Keep CSS lightweight.
* Avoid heavy SVG masks or expensive filters beyond `backdrop-filter: blur(...)`.
* Ensure modal area is `-webkit-app-region: no-drag` if you use draggable window headers.

## Target Structure

### HTML (keep semantic + simple)

Use or adapt this structure in the renderer HTML:

```html
<div id="deviceOverlay" class="overlay hidden" aria-hidden="true">
  <div class="modal" role="dialog" aria-modal="true" aria-labelledby="deviceTitle">
    <h2 id="deviceTitle">Connect to Device</h2>

    <ul id="deviceList" class="device-list">
      <!-- Render device items here -->
      <!-- Example item:
      <li class="device local selected" data-device="local">
        <div class="device-main">This Computer</div>
        <div class="device-sub">Local Playback</div>
      </li>
      -->
    </ul>

    <button id="deviceCancelBtn" class="btn cancel" type="button">Cancel</button>
  </div>
</div>
```

Notes:

* Use `hidden` class to toggle visibility.
* Each `<li>` must have `data-device="<name-or-id>"` for click handling.
* Selected item uses `.selected`.

## CSS (Glassmorphism Modal)

Add/merge this CSS into your stylesheet:

```css
/* Overlay */
.overlay {
  position: fixed;
  inset: 0;
  background: rgba(20, 10, 35, 0.45);
  backdrop-filter: blur(14px);
  display: flex;
  align-items: center;
  justify-content: center;
  z-index: 1000;
}

.hidden { display: none !important; }

/* Modal */
.modal {
  width: min(420px, calc(100vw - 48px));
  padding: 22px;
  border-radius: 22px;
  background: rgba(30, 30, 40, 0.82);
  border: 1px solid rgba(255,255,255,0.12);
  box-shadow: 0 30px 80px rgba(0,0,0,0.6);
  color: #fff;
  animation: pop 0.22s ease;
  -webkit-app-region: no-drag;
}

@keyframes pop {
  from { transform: scale(0.94); opacity: 0; }
  to   { transform: scale(1); opacity: 1; }
}

.modal h2 {
  margin: 0 0 14px;
  text-align: center;
  font-size: 20px;
}

/* Device list */
.device-list {
  list-style: none;
  padding: 0;
  margin: 0 0 18px;
  max-height: 360px;
  overflow: auto;
}

/* Device row */
.device {
  padding: 12px 14px;
  border-radius: 14px;
  margin-bottom: 8px;
  cursor: pointer;
  background: rgba(255,255,255,0.05);
  transition: transform 0.15s ease, background 0.15s ease, box-shadow 0.15s ease;
}

.device:hover {
  background: rgba(255,255,255,0.10);
  transform: translateY(-1px);
}

.device .device-main {
  font-size: 15px;
}

.device .device-sub {
  margin-top: 3px;
  font-size: 12px;
  opacity: 0.7;
}

/* Selected device */
.device.selected {
  background: linear-gradient(135deg, #c77dff, #8b5cf6);
  box-shadow: 0 0 18px rgba(199,125,255,0.65);
  color: #111;
}

.device.selected .device-sub {
  opacity: 0.85;
}

/* Optional: disabled group devices */
.device.disabled {
  opacity: 0.45;
  pointer-events: none;
}

/* Cancel button */
.btn.cancel {
  width: 100%;
  padding: 12px;
  border-radius: 999px;
  border: none;
  background: #d16b7d;
  color: #fff;
  font-size: 15px;
  cursor: pointer;
  transition: transform 0.15s ease;
}

.btn.cancel:hover {
  transform: scale(1.02);
}
```

## JavaScript Behavior (Minimal)

### Selection logic

* When a device row is clicked:

  1. Remove `.selected` from all device `<li>`
  2. Add `.selected` to clicked `<li>`
  3. Call existing “connect/cast to device” handler with `data-device`

Pseudo-code (adapt to existing app code):

```js
deviceList.addEventListener("click", (e) => {
  const item = e.target.closest(".device");
  if (!item) return;

  deviceList.querySelectorAll(".device.selected")
    .forEach(el => el.classList.remove("selected"));

  item.classList.add("selected");

  const deviceName = item.dataset.device;
  // call existing connect logic:
  // connectToDevice(deviceName);
});
```

### Close modal

* Cancel button closes modal (existing function):

```js
deviceCancelBtn.addEventListener("click", closeDeviceModal);
```

### Optional: close on overlay click

* Only if app UX allows:

```js
deviceOverlay.addEventListener("click", (e) => {
  if (e.target === deviceOverlay) closeDeviceModal();
});
```

## Acceptance Criteria

* Popup visually matches glassmorphism theme.
* Overlay dims and blurs background.
* Device list has hover + selected glow.
* Exactly one device can be selected.
* Cancel closes modal.
* Runs smoothly in Tauri WebView without lag.

---

## Notes / Future Enhancements (Optional)

* Mark “Speaker Groups” as `.disabled` if casting library can’t support them.
* Add small icons per device type (local vs cast).
* Remember last selected device and preselect it on open.
