    inset-inline-start 是一个 CSS 属性,它定义了一个元素的逻辑行内起始内边距。这个内边距会根据元素的书写模式、方向性和文本方向映射到物理偏移。它对应于 top、right、bottom 或 left 属性,具体取决于为 writing-mode、direction 和 text-orientation 定义的值。
此 插入属性 对非定位元素没有影响。

    <p>
      As much mud in the streets as if the waters had but newly retired from the
      face of the earth, and it would not be wonderful to meet a Megalosaurus,
      forty feet long or so, waddling like an elephantine lizard up Holborn
      Hill.
    </p>
  </div>
</section>
#example-element {
  border: 0.75em solid;
