如何向amp-image-lightbox添加关闭按钮？通过单击图像外部将其关闭，但是如果长宽比匹配显示应该怎么办？代码片段如下：

$rnd = rand(10000,20000);
$res = '<amp-img on="tap:lightbox'.$rnd.'" role="button" tabindex="0" src="'.$src[1].'" width="'.$width.'" height="'.$height.'" layout="intrinsic" '.$style.'></amp-img>';
$res.= '<amp-image-lightbox id="lightbox'.$rnd.'" layout="nodisplay"></amp-image-lightbox>';

## Introduction

An AMP HTML tutorial - learn the different building blocks of an AMP HTML file. AMP HTML is entirely built on existing web technologies. It achieves reliable performance by restricting some parts of HTML, CSS and JavaScript. To make up for those limitations AMP HTML defines a set of custom elements for rich content beyond basic HTML. This samples shows what's necessary to create a valid AMP HTML file.

<!-- -->
<!-- Doctype declaration is required. -->
<!doctype html>
<!-- This tells everyone that this is an AMP file. `<html amp>` works too. -->
<html ⚡>
<!-- ## Head -->
<!-- -->
<head>
  <!-- The charset definition must be the first child of the `<head>` tag. -->
  <meta charset="utf-8">
  <title> amp-image-lightbox</title>
  <!-- The AMP runtime must be loaded as the second child of the `<head>` tag.-->

    AMP HTML files require a canonical link pointing to the regular HTML. If no HTML version exists, it should point to itself.

  <!--
    AMP HTML files require a viewport declaration. It's recommended to include initial-scale=1.

Answer 2

没有html代码，只有CSS。将此放在您的样式上：

对于amp-image-lightbox：

#lightbox1::before {
  content:"X";
  cursor: pointer;
  font-size: 32px;
  right:19px;
  top:8px;
  font-weight: 600;
  position: fixed;
  display: block;
  text-align:right;
  color:#fff;
}

选择器是默认的示例选择器。确保它是正确的。

在放大器灯箱上：

.lightbox::before {
  content:"X";
  cursor: pointer;
  font-size: 32px;
  right:19px;
  top:8px;
  font-weight: 600;
  position: fixed;
  display: block;
  text-align:right;
 color:#fff;
}
