如何突出显示背景颜色不是与文本全高，而是与底部对齐而不是顶部对齐的文本？

<div class="highlight-text">Example Text</div>

<style>
.highlight-text {
  display: inline-block;
  vertical-align: bottom;
  background-color: yellow;
  height: 1.5em;
  line-height: 1.5em;
}
</style>

<div class="highlight-text">Example Text</div>

<style>
.highlight-text {
  position: relative;
}

.highlight-text::after {
  content: "";
  display: block;
  position: absolute;
  bottom: 0;
  left: 0;
  width: 100%;
  height: 20px;
  background-color: yellow;
  z-index: -1;
}
</style>
