Formal syntax​

Examples​

length-percentage examples​

The following simple example demonstrates several properties that use <length-percentage> values.

HTML​

<p>You can use percentages and lengths in so many places.</p>

CSS​

p {
  /* length-percentage examples */
  width: 75%;
  height: 200px;
  margin: 3rem;
  padding: 1%;
  border-radius: 10px 10%;
  font-size: 250%;
  line-height: 1.5em;

  /* length examples */
  text-shadow: 1px 1px 1px red;
  border: 5px solid red;
  letter-spacing: 3px;

  /* percentage example */
  text-size-adjust: 20%;
}

Result​

{{EmbedLiveSample('length-percentage_examples', '100%', 320)}}

Use in calc()​

Where a <length-percentage> is specified as an allowable type, this means that the percentage resolves to a length and therefore can be used in a {{cssxref("calc", "calc()")}} expression. Therefore, all of the following values are acceptable for {{cssxref("width")}}:

width: 200px;
width: 20%;
width: calc(100% - 200px);
