将渐变边框底部添加到<hr />数据内容文本

Question

到目前为止，我有这个＆lt; hr＆gt;使用数据内容中的“关于我”文本。

我想在文字＆＃34;关于我＆＃34;下添加三种颜色的线性渐变边框底部。喜欢下划线。我已尝试在.section-divider中设置背景：在线性渐变和填充之后，所有这些但最终将整个背景设置为线性渐变。

HTML：

<hr class="section-divider" data-content="ABOUT ME"></hr>

CSS：

.section-divider {
  font-family: Lato-Regular;
  line-height: 1em;
  position: relative;
  outline: 0;
  border: 0;
  color: black;
  text-align: left;
  height: 1.5em;
  font-size: 20px;
}
.section-divider:before {
  content: '';
  background: black;
  position: absolute;
  left: 0;
  top: 50%;
  width: 100%;
  height: 1px;
}
.section-divider:after {
  content: attr(data-content);
  position: relative;
  display: inline-block;
  color: black;
  padding: 0 .5em;
  line-height: 1.5em;
  color: black;
  background-color: white;
}

如果有人知道如何做到这一点或更好的方法来做到这一点，文字对齐左边更好一般让我知道，谢谢！
