`white-space` CSS property

The white-space CSS property sets how white space inside an element is handled.

Try it

white-space: normal;

white-space: pre;

white-space: pre-wrap;

white-space: pre-line;

white-space: wrap;

white-space: collapse;

white-space: preserve nowrap;

<section class="default-example" id="default-example">
  <div id="example-element">
    <p>
      But ere she from the church-door stepped She smiled and told us why: 'It
      was a wicked woman's curse,' Quoth she, 'and what care I?' She smiled, and
      smiled, and passed it off Ere from the door she stept—
    </p>
  </div>
</section>

#example-element {
  width: 16rem;
}

#example-element p {
  border: 1px solid #c5c5c5;
  padding: 0.75rem;
  text-align: left;
}

The property specifies two things:

Whether and how white space is collapsed.
Whether and how lines wrap.

Note: To make words break within themselves, use overflow-wrap, word-break, or hyphens instead.

Constituent properties

This property is a shorthand for the following CSS properties:

Note: The spec defines a third constituent property: white-space-trim, which is not implemented in any browser yet.

Syntax

css

/* Single keyword values */
white-space: normal;
white-space: pre;
white-space: pre-wrap;
white-space: pre-line;

/* white-space-collapse and text-wrap-mode shorthand values */
white-space: nowrap;
white-space: wrap;
white-space: break-spaces;
white-space: collapse;
white-space: preserve nowrap;

/* Global values */
white-space: inherit;
white-space: initial;
white-space: revert;
white-space: revert-layer;
white-space: unset;

Values

The white-space property values can be specified as one or two keywords representing the values for the white-space-collapse and text-wrap-mode properties, or the following special keywords:

normal: Sequences of white space are collapsed. Newline characters in the source are handled the same as other white spaces. Lines are broken as necessary to fill line boxes. Equivalent to collapse wrap.
pre: Sequences of white space are preserved. Lines are only broken at newline characters in the source and at <br> elements. Equivalent to preserve nowrap.
pre-wrap: Sequences of white space are preserved. Lines are broken at newline characters, at <br>, and as necessary to fill line boxes. Equivalent to preserve wrap.
pre-line: Sequences of white space are collapsed. Lines are broken at newline characters, at <br>, and as necessary to fill line boxes. Equivalent to preserve-breaks wrap.

Note: The white-space property as a shorthand is a relatively new feature (see browser compatibility). Originally, it had six keyword values; now, the value nowrap is instead interpreted as a value for text-wrap-mode, while the value break-spaces is interpreted as a value for white-space-collapse. The above four keywords are still specific to white-space, but they have longhand equivalents. The change to make white-space a shorthand expands acceptable values to even more keywords and combinations, such as wrap and collapse.

The following table summarizes the behavior of these four white-space keyword values:

	New lines	Spaces and tabs	Text wrapping	End-of-line spaces	End-of-line other space separators
`normal`	Collapse	Collapse	Wrap	Remove	Hang
`pre`	Preserve	Preserve	No wrap	Preserve	No wrap
`pre-wrap`	Preserve	Preserve	Wrap	Hang	Hang
`pre-line`	Preserve	Collapse	Wrap	Remove	Hang

A tab defaults to 8 spaces and can be configured using the tab-size property. In the case of normal, nowrap, and pre-line values, every tab is converted to a space (U+0020) character.

Note: There is a distinction made between spaces and other space separators. These are defined as follows:

spaces: Spaces (U+0020), tabs (U+0009), and segment breaks (such as newlines).
other space separators: All other space separators defined in Unicode, other than those already defined as spaces.

Where white space is said to hang, this can affect the size of the box when measured for intrinsic sizing.

Result

Multiple lines in SVG text element

The white-space CSS property can be used to create multiple lines in a <text> element, which does not wrap by default.

HTML

The text inside the <text> element needs to be split into multiple lines for the new lines to be detected. After the first line the rest need to have their whitespace removed.

html

<svg viewBox="0 0 320 150">
  <text y="20" x="10">Here is an English paragraph
that is broken into multiple lines
in the source code so that it can
be more easily read and edited
in a text editor.
  </text>
</svg>

CSS

css

text {
  white-space: break-spaces;
}
