padding-right

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

padding-right CSS 属性设置了元素右侧内边距区域的宽度。

尝试一下

padding-right: 1.5em;
padding-right: 10%;
padding-right: 20px;
padding-right: 1ch;
padding-right: 0;
<section id="default-example">
  <div class="transition-all" id="example-element">
    <div class="box">
      Far out in the uncharted backwaters of the unfashionable end of the
      western spiral arm of the Galaxy lies a small unregarded yellow sun.
    </div>
  </div>
</section>
#example-element {
  border: 10px solid #ffc129;
  overflow: hidden;
  text-align: left;
}

.box {
  border: dashed 1px;
}

元素的内边距区域是其内容和边框之间的空间。

备注: 通过 padding 属性,只需一次声明,就可以为元素的所有四边设置内边距。

/* <length> 值 */
padding-right: 0.5em;
