Answer 1

我创建了这个简单的 css 图像/照片库：

* {
  margin: 0;
  padding: 0;
}

body {
  background-color: black;
}

.container {
  width: 100%;
  height: 100%;
}

.top {
  display: flex;
  width: 80vw;
  height: 80vh;
  margin-top: 10vh;
  margin-left: auto;
  margin-right: auto;
  margin-bottom: 10vh;
}

.top ul {
  list-style: none;
  width: 100%;
  height: 100%;
  z-index: 1;
  box-sizing: border-box;
}

.top ul li {
  position: relative;
  float: left;
  width: 25%;
  height: 25%;
  overflow: hidden;
}

.top ul li::before {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: #000;
  content: "";
  color: white;
  opacity: 0.4;
  text-align: center;
  box-sizing: border-box;
  pointer-events: none;
}

.top ul li:hover::before {
  opacity: 0;
  background-color: rgba(0, 0, 0, 0.9);
}

.top ul li img {
  width: 100%;
  height: auto;
  overflow: hidden;
}

.lightbox {
  position: fixed;
  width: 100%;
  height: 100%;
  text-align: center;
  top: 0;
  left: 0;
  background-color: rgba(0, 0, 0, 0.75);
  z-index: 999;
  opacity: 0;
  pointer-events: none;
}

.lightbox img {
  max-width: 90%;
  max-height: 80%;
  position: relative;
  top: -100%;
}

.lightbox:target {
  outline: none;
  top: 0;
  opacity: 1;
  pointer-events: auto;
}

.lightbox:target img {
  top: 0;
  top: 50%;
  transform: translateY(-50%);
  -moz-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
  -o-transform: translateY(-50%);
  -webkit-transform: translateY(-50%);
}

<div class="container">
  <div class="top">
    <ul>

Answer 2

当图片处于查看模式时，您可以为图片添加“x”或“关闭”按钮，或者可能只需要使用“esc”键
