Google AMP - 布局

AMP-Layout 是 Google-amp 中的重要功能之一。Amp Layout 可确保页面加载时正确呈现 amp 组件,而不会引起任何闪烁或滚动问题。 Google AMP 确保在任何其他远程资源(如图像的 http 请求、数据调用)之前在页面上完成布局渲染。

布局属性列表如下。

  • width 和 height

  • layout

  • sizes

  • heights

  • media

  • placeholder

  • fallback

  • noloading

我们将在本章中详细考虑 layout 属性。其余属性将在 − 章中详细讨论。本教程的 Google AMP – 属性

布局属性

我们可以在 amp-component 上使用布局属性,该属性将决定组件在页面内的呈现方式。amp 支持的布局列表如下 −

  • Not Present

  • Container

  • fill

  • fixed

  • fixed-height

  • flex-item

  • intrinsic

  • nodisplay

  • Responsive

对于每个布局,我们将看到一个工作示例,该示例将展示布局属性如何以不同的方式呈现 amp-component。我们将在示例中使用 amp-img 组件。

固定和固定高度示例

在了解固定和固定高度的用法之前,请注意以下两点 −

  • layout="fixed" 需要有宽度和高度,amp-component 将显示在其中。

  • layout="fixed-height" 需要为组件指定高度。它将确保高度不会改变。使用固定高度时不得指定宽度,否则可以是自动的。

nodisplay 和 responsive

layout = nodisplay 的 Amp 组件不会占用页面上的任何空间,就像 display:none 一样。无需向此类布局添加任何 width 和 height 属性。

layout = responsive 的 Amp 组件将占用页面的可用空间或宽度,高度会调整大小以保持元素的纵横比。

Google AMP 支持的布局列表如下

  • 手风琴

  • 轮播

  • 灯箱

  • 滑块

  • 侧边栏

Amp- 手风琴

Amp-accordion 是一个 amp 组件,用于以展开-折叠格式显示内容。用户可以轻松地在移动设备上查看它,他们可以从手风琴中选择他们喜欢的部分。

要使用 amp-accordion,您需要添加以下脚本 −

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

Amp-accordion 标签

<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-accordion>

Amp nodisplay Accordion

Amp-accordion 内部包含部分。每个部分可以有 2 个子部分,如果超过 2 个子部分,浏览器控制台中将显示错误。您可以在部分中添加容器,其中可以包含多个元素。

默认情况下,我们使用扩展到部分的属性将一个部分保持在扩展模式。

自动折叠手风琴

对于自动折叠,我们在 amp-accordion 上使用属性 expand-single-section,如示例所示。用户打开的部分将仅保持扩展状态,其他部分将使用 expand-single-section 属性关闭。

AMP Carousel

Amp-carousel 是一个 amp-component,用于在屏幕上显示一组类似的内容,并使用箭头在内容之间切换。

要使用 amp-carousel,我们需要添加以下脚本 −

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

Amp-carousel 标签

amp-carousel 标签如下所示 −

<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 可用的属性

amp-carousel 可用的属性列于下表 −

Sr.No 属性 &描述
1 type

我们可以将轮播项目显示为轮播和幻灯片

2 height

轮播的高度(以像素为单位)

3 controls (可选)

它在屏幕上显示左/右箭头。它在设备上几秒钟后消失。可以使用 CSS 使箭头始终可见。

4 data-next-button-aria-label (可选)

用于设置下一个轮播的标签。

5 data-prev-button-aria-label(可选)

用于设置上一个轮播的标签。

6 autoplay(可选)

用于在 5000 毫秒后显示下一张幻灯片。可以使用 amp-carousel 上的延迟属性(不带毫秒)覆盖它。它将为轮播添加循环属性,幻灯片将在到达末尾后再次播放。仅适用于 type=slides,并且至少需要 2 张幻灯片才能自动播放。

现在,让我们通过示例来以不同方式显示轮播。

Amp 轮播类型为轮播

使用轮播类型,项目可水平滚动。

动画轮播类型幻灯片

使用自动播放的 Amp 轮播

在下面给出的示例中,我们添加了延迟为 2000 毫秒(2 秒)的自动播放属性。这将在延迟 2 秒后更改幻灯片。默认情况下,延迟为 5000 毫秒(5 秒)。

Amp 侧边栏

Amp 侧边栏是 amp 组件,用于显示点击按钮即可从窗口两侧滑动的内容。

要使用 amp-sidebar,我们需要添加以下脚本 −

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

Amp-sidebar 标签

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

amp-sidebar 上可用的属性列表如下 −

Sr.no 属性和说明
1 side

此属性将按指定的方向打开侧边栏。示例左/右

2 layout

侧边栏布局将使用Nodisplay

3 open

侧边栏打开时会添加此属性。

4 data-close-button-aria-label

用于设置关闭按钮的标签。

我们将使用上述属性处理侧边栏。观察下面显示的示例 −

输出

AMP Slidebar

我们使用 side 属性在右侧打开侧边栏。您可以使用 side 属性的 left 值在左侧打开侧边栏。layout 属性必须为 nodisplay.Open 属性,侧边栏打开时才会显示该属性。

data-close-button-aria-label

属性用于添加关闭按钮。它是可选的,并非强制使用。

Amp Image Slider

Amp-image-slider 是一个 amp 组件,用于通过在图像上垂直移动滑块来比较两幅图像。

要使用 amp-img-slider,请添加以下脚本 −

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

Amp-img-slider 标签

<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>

此处显示了 amp-img-slider 的一个示例。我们在 amp-img-slider 中添加了 2 张图片,其中第一张图片充当滑块,您可以在第二张图片的顶部滑入。
