html - 带图标的CSS图片叠加效果

Question

我目前正在尝试制作一个带有图标滑入的图像叠加动画，但不知道如何在代码中执行。我找不到应用动画的方法。我有我想要的动画类型的插入链接。

叠加动画演示:

如果有人能做到，请帮助我。以下是我到目前为止尝试过的代码:

Answer 1

我相信这就是你想要的。

在每个 anchor 标签之后，您可以插入:

<div class="overlay">
  <span class='icon'>+</span>
</div>

下面的 CSS 样式覆盖层和 + 符号，就像您在图片中看到的那样。

查看此代码段。我还在下面发布了一个演示。

@import url('https://fonts.googleapis.com/css?family=Pacifico');

  list-style: none;
  text-align: center;
  width: 100%;
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}

.xop-grid:after {
  clear: both;
}

.xop-grid:after,
.xop-box:before {
  content: '';
}

.xop-grid li {
  width: 700px;
  height: 450px;
  margin: 30px 27px;
  padding: 0;
}

.xop-box {

.xop-box .overlay {
