The <relative-size> CSS data type describes relative size keywords. The <relative-size> keywords define a size relative to the computed size of the parent element. This data type is used in the font shorthand and font-size properties.

Syntax

<relative-size> = smaller | larger

Values

The <relative-size> data type is defined using a keyword value chosen from the list below.

smaller

A relative size one size smaller than the inherited size.

larger

A relative size one size larger than the inherited size.

Description

The <relative-size> keywords are relative to the current size of the element. If the inherited size is defined using an <absolute-size> keyword, the <relative-size> value equates to the adjacent size in the <absolute-size> table. Otherwise, the relative increase or decrease in size is between 120% and 150%.

Examples

Comparing the keyword values

<ul>
  <li class="smaller">font-size: smaller;</li>
  <li>font-size is not specified</li>
  <li class="larger">font-size: larger;</li>
</ul>

li {
  margin-bottom: 0.3em;
}
.smaller {
  font-size: smaller;
}
.larger {
