javascript - 显示 :target popup on page load With PURE CSS

Question

我知道这是基本问题。但我无法通过它。我只有纯 CSS 中的弹出窗口代码，它会在单击链接标记时弹出。我希望使用 jquery 或 Pure JS 在页面加载时加载此弹出窗口。

请注意，在 CSS 中，我已将“.overlay”类的可见性值设置为无，并在单击时更改为可见。我试图触发点击页面加载并更改页面加载的可见性。不幸的是，两者都失败了。我已经添加了代码片段。帮助我的 friend 。

$(document).ready(function() {
    $("#popup1").trigger('click');
});

.overlay {
  position: fixed;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.7);
  transition: opacity 500ms;
  visibility: hidden;
  opacity: 0;
}
.overlay:target {
  visibility: visible;
  opacity: 1;
}

.popup {
  margin: 70px auto;
  padding: 20px;
  background: #fff;
  border-radius: 5px;
  width: 30%;
  position: relative;
  transition: all 5s ease-in-out;
}

.popup h2 {
  margin-top: 0;
  color: #333;
  font-family: Tahoma, Arial, sans-serif;
}
.popup .close {
  position: absolute;
  top: 20px;
  right: 30px;
  transition: all 200ms;
  font-size: 30px;
  font-weight: bold;
  text-decoration: none;
  color: #333;
}
.popup .close:hover {
  color: #06D85F;
}
.popup .content {
  max-height: 30%;
  overflow: auto;
}

如果你确实想使用 Javascript，你可以通过手动设置哈希来实现:

$(document).ready(function() {
  window.location.hash = "#popup1";
});

.overlay {
  position: fixed;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.7);
  transition: opacity 500ms;
  visibility: hidden;
  opacity: 0;
}
.overlay:target {
  visibility: visible;
  opacity: 1;
}

.popup {
  margin: 70px auto;
  padding: 20px;
  background: #fff;
  border-radius: 5px;
  width: 30%;
  position: relative;
  transition: all 5s ease-in-out;
}

.popup h2 {
  margin-top: 0;
  color: #333;
  font-family: Tahoma, Arial, sans-serif;
}
.popup .close {
  position: absolute;
  top: 20px;
  right: 30px;
  transition: all 200ms;
  font-size: 30px;
  font-weight: bold;
  text-decoration: none;
  color: #333;
}
.popup .close:hover {
  color: #06D85F;
}
.popup .content {
  max-height: 30%;
  overflow: auto;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="popup1" class="overlay">
  <div class="popup">
    <h2>Notification</h2>
    <a class="close" href="#">&times;</a>
    <div class="content">
      App is under-construction.
