在Squarespace博客上创建READ MORE函数

Question

我正在尝试在博客上创建READ MORE函数，例如this。

此示例中的代码在实现到我的布局中时可以使用，但是问题是我不能再使用Squarespace编辑器在显示行下方创建任何内容。我必须手动编写所有代码，这在大量博客上是不值得的。

还有其他方法吗？也许在页面下方使用另一个div并显示两者之间的所有内容？

谢谢。

摘要：

function hideReadMore() {
  document.getElementById('readmoretext').className = 'visiblediv';
  document.getElementById('readmorebutton').className = 'hiddendiv';

}

.visiblediv {
  display: block;
}

.hiddendiv {
  display: none;
}

.readmorediv {
  width: 200px;
  margin: 0 auto;
}

.readmorebutton {
  width: 100%;
  height: auto;
  padding: 0px;
  background-color: #fff;
  border: 1px solid black;
  font-family: "Montserrat", "Open Sans", sans-serif;
  font-size: 14px;
  line-height: 2.75em;
  font-weight: bold;
  font-style: b;
  color: #f1592a;
  text-transform: uppercase !important;
  letter-spacing: 2px;
  text-align: center;
  text-decoration: none;
  cursor: pointer;
  outline: none;
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  display: block;
  margin-top: 25px;
}
