Google AMP - 佈局

上一頁
下一頁

AMP 佈局是 Google AMP 中一個重要的功能。AMP 佈局確保在頁面載入時 AMP 元件能夠正確渲染，不會出現任何閃爍或滾動問題。Google AMP 確保在執行任何其他遠端資源（如圖片的 HTTP 請求、資料呼叫）之前完成頁面的佈局渲染。

下面列出了佈局屬性。

  • 寬度和高度

  • 佈局

  • 尺寸

  • 高度

  • 媒體

  • 佔位符

  • 備用內容

  • noloading (無載入)

本章將詳細介紹layout 屬性。其餘屬性將在本教程的Google AMP – 屬性章節中詳細討論。

Layout 屬性

可以在 amp-component 上使用 layout 屬性，它將決定元件如何在頁面內渲染。AMP 支援的佈局列表如下：

  • 不存在

  • 容器

  • 填充 (fill)

  • 固定 (fixed)

  • 固定高度 (fixed-height)

  • 彈性專案 (flex-item)

  • 內在 (intrinsic)

  • 不顯示 (nodisplay)

  • 響應式 (Responsive)

對於每種佈局，我們將看到一個工作示例，展示 layout 屬性如何以不同的方式渲染 amp-component。在我們的示例中，我們將使用amp-img元件。

固定和固定高度示例

在瞭解 fixed 和 fixed-height 的用法之前，請注意以下兩點：

  • layout=”fixed” 需要指定寬度和高度，amp-component 將顯示在該尺寸內。

  • layout=”fixed-height” 需要指定元件的高度。它將確保高度不變。使用 fixed-height 時，不得指定寬度，或者可以設定為 auto。

帶有 layout = nodisplay 的 AMP 元件不會佔用頁面上的任何空間，就像 display:none 一樣。無需為此類佈局新增任何寬度和高度屬性。

帶有 layout = responsive 的 AMP 元件將佔用可用空間或頁面的寬度，並保持元素的縱橫比調整高度。

Google AMP 支援的佈局列表如下：

  • 手風琴

  • 輪播

  • 燈箱

  • 滑塊

  • 側邊欄

Amp-Accordion (手風琴)

amp-accordion 是一個用於以展開-摺疊格式顯示內容的 AMP 元件。它使使用者更容易在移動裝置上檢視內容，他們可以根據自己的選擇從手風琴中選擇部分。

要使用 amp-accordion，需要新增以下指令碼：

<script async custom-element = "amp-accordion" 
   src = "https://cdn.ampproject.org/v0/amp-accordion-0.1.js">
</script>

Amp-accordion 標籤

<amp-accordion>
   <section class = "seca">
      <h3>Content 1</h3>
      <div>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
      </div>
   </section>
   …

Amp nodisplay Accordion

amp-accordion 包含其內部的節。每個節可以有兩個子元素，超過兩個子元素將在瀏覽器控制檯中顯示錯誤。您可以在節中新增一個容器，並在其中包含多個元素。

預設情況下，我們使用 expanded 屬性將一個節保持在展開模式。

自動摺疊手風琴

對於自動摺疊，我們在 amp-accordion 上使用expand-single-section 屬性，如示例所示。使用者開啟的節將保持展開狀態，其餘節將使用expand-single-section 屬性關閉。

AMP 輪播

amp-carousel 是一個 AMP 元件，用於在螢幕上顯示一組類似的內容，並使用箭頭在內容之間切換。

要使用 amp-carousel，需要新增以下指令碼：

<script async custom-element = "amp-carousel" src = "https://cdn.ampproject.org/v0/amp-carousel-0.1.js"></script>

amp-carousel 標籤

amp-carousel 標籤如下所示：

<amp-carousel height="300" layout="fixed-height" type="carousel">
      <amp-img src="images/christmas1.jpg" width="400" height="300" alt="a sample image"></amp-img>
   ….
</amp-carousel>

amp-carousel 可用屬性

amp-carousel 可用屬性列在下表中：

序號 屬性 & 描述
1 type

我們可以將輪播專案顯示為輪播和幻燈片
2 height

輪播高度（以畫素為單位）
3 controls (可選)

它在螢幕上顯示左右箭頭。在某些裝置上，它會在幾秒鐘後消失。可以使用 CSS 使箭頭始終可見。
4 data-next-button-aria-label (可選)

用於設定下一個輪播的標籤。
5 data-prev-button-aria-label (可選)

用於設定上一個輪播的標籤。
6 autoplay (可選)

用於在 5000 毫秒後顯示下一張幻燈片。可以使用 amp-carousel 上的 delay 屬性（以毫秒為單位）覆蓋它。它會將 loop 屬性新增到輪播，幻燈片到達結尾後會再次播放。僅用於 type=slides，並且至少需要 2 張幻燈片才能使自動播放生效。

現在，讓我們透過示例來了解如何以不同的方式顯示輪播。

Amp 輪播型別為輪播

使用輪播型別，專案可以水平滾動。

使用自動播放的 Amp 輪播

在下面的示例中，我們添加了 autoplay 屬性，延遲為 2000 毫秒（2 秒）。這將在 2 秒的延遲後更改幻燈片。預設延遲為 5000 毫秒（5 秒）。

AMP 燈箱

amp-lightbox 是一個 AMP 元件，它將佔據整個視口並像疊加層一樣顯示。

要使用 amp-lightbox，請新增以下指令碼：

<script async custom-element = "amp-lightbox" src = "https://cdn.ampproject.org/v0/amp-lightbox-0.1.js">
</script>

amp-lightbox 可用屬性

amp-lightbox 屬性列表如下：

序號 屬性 & 描述
1 animate-in (可選)

在這裡，您可以指定開啟燈箱的動畫樣式。預設情況下為

淡入 (fade-in)

支援的樣式值為 fade-in、fly-in-bottom 和 fly-in-top
2 close-button (在 AMPHTML 廣告中必需)

當用於 amphtmlads 時，我們可以為燈箱指定關閉按鈕。
3 id (必需)

燈箱的唯一識別符號
4 layout (必需)

layout 的值為 nodisplay
5 Scrollable (可選)

使用此 amp-lightbox 屬性，可以滾動燈箱的內容，超過燈箱的高度。

AMP Overlay

Amp 側邊欄

amp-sidebar 是一個 AMP 元件，用於顯示在點選按鈕時從視窗側面滑出的內容。

要使用 amp-sidebar，需要新增以下指令碼：

<script async custom-element = "amp-sidebar" src = "
   https://cdn.ampproject.org/v0/amp-sidebar-0.1.js">
</script>

amp-sidebar 標籤

<amp-sidebar id = "sidebar" layout = "nodisplay" side = "right">
   <span on = "tap:sidebar.close">X</span>
   Html content here..
</amp-sidebar>

amp-sidebar 可用屬性列表如下：

序號 屬性 & 描述
1 side

此屬性將按照指定的方向開啟側邊欄。例如 left/right
2 佈局

側邊欄佈局將使用 nodisplay
3 open

開啟側邊欄時新增此屬性。
4 data-close-button-aria-label

用於設定關閉按鈕的標籤。

我們將使用上述屬性來處理側邊欄。請觀察下面的示例：

AMP Slidebar

我們使用side 屬性在右側開啟側邊欄。您可以使用 left 值作為side 屬性在左側開啟它。layout 屬性必須為nodisplay。開啟側邊欄時存在open 屬性。

data-close-button-aria-label

屬性用於新增關閉按鈕。它是可選的，並非必須使用。

Amp 圖片滑塊

amp-image-slider 是一個 AMP 元件，用於透過新增滑塊並在垂直方向上移動它來比較兩張圖片。

要使用 amp-img-slider，請新增以下指令碼：

<script async custom-element = "amp-image-slider" src = "
   https://cdn.ampproject.org/v0/amp-image-slider-0.1.js">
</script>

amp-img-slider 標籤

<amp-image-slider width = "300" height = "200" layout = "responsive">
   <amp-img src = "images/christmas1.jpg" layout = "fill">
   </amp-img>
   <amp-img src = "images/christmas2.jpg" layout = "fill">
   </amp-img>
</amp-image-slider>

此處顯示 amp-img-slider 的示例。在這裡，我們在 amp-img-slider 中添加了 2 張圖片，其中第一張圖片充當滑塊，您可以將其滑到第二張圖片的頂部。
