CSS:文本修饰无法删除上线

Question

我正在尝试使用p::first-letter选择器从第一个字母中删除文本修饰.但由于某种未知的原因,我无法做到这一点.

p::first-line {
  font-weight: bold;
  text-decoration: overline;
}
p::first-letter {
  text-decoration: none;
  /*text-decoration-color: rgba(59, 119, 191, 0.68);*/
  display: block;
  color: red;
  font-weight: bold;
  background-color: rgba(59, 119, 191, 0.68);
  margin: 0px 2px 1px 0;
  padding: 5px 13px 5px 11px;
  color: #b1ffea;
}

<h2>Heading <a href="#"><span class="anchor">#</span></a></h2>

更新:

好的,我通过启用"实验性Web平台功能"让Chrome工作.由于某种原因,前缀-webkit-无法触发此行为.这是工作代码.

p::first-letter{
        text-decoration: overline;
        text-decoration-color: rgba(59, 119, 191, 0.68);
        display: block;
        color: red;
        font-weight: bold;
        background-color: rgba(59, 119, 191, 0.68);
        margin: 0px 2px 1px 0;
        padding: 5px 13px 5px 11px;
        color: #b1ffea;
    }

Answer 1

只需添加:

p::first-letter {
    float: left;
}

所以它是:

p::first-line {
  font-weight: bold;
  text-decoration: overline;
}
p::first-letter {
  float: left;
  text-decoration: none;
  /*text-decoration-color: rgba(59, 119, 191, 0.68);*/
  display: block;
  color: red;
  font-weight: bold;
  background-color: rgba(59, 119, 191, 0.68);
  margin: 0px 2px 1px 0;
  padding: 5px 13px 5px 11px;
  color: #b1ffea;
}
