如何从背景中去除绿色并将其变为透明

Answer 1

在数据集选项中将填充属性设置为false

<div id="parent">
  <p>read me read me read me</p>
  <div class="ignore-me">and thus ignore this text</div>
  <p>read me read me read me</p>
  <script class="ignore-me"></script>
  <p>read me read me read me</p>
  <link class="ignore-me">
</div>

<button id="Bt-Copy">copy to clipboard (except red part)</button>
