jsfiddle 和 codepen 上相同 html/css 代码之间无法解释的区别

Unexplainable difference between same html/css code on jsfiddle and codepen

我有相同的 html / css 代码,但输出仅适用于 codepen 而不是 jsfiddle。怎么来的?

html

<div class="spring">
  <div class="text">These are words</div>
  <div class="sect sect1">
    <div class="text">written down</div>
    <div class="sect sect2">
      <div class="text">and</div>
      <div class="sect sect3">
        <div class="text">even further down.</div>
      </div>
    </div>
  </div>
</div>

css

}

那是因为 jsfiddle 中的 css 设置为 css 而它需要 scss .

单击 css 部分中的设置选项,然后从 Language select SCSS in jsfiddle 的下拉列表中单击,这样就可以了
