white-space

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.

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

Try it

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.

Syntax

css

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

/* white-space-collapse and text-wrap shorthand values */
white-space: collapse balance;
white-space: preserve nowrap;

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

white-space property values can be specified as a single keyword chosen from the list of values below, or two values representing shorthand for the white-space-collapse and text-wrap properties.

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.

nowrap

Collapses white space as the normal value does, but suppresses line breaks (text wrapping) within the source.

pre

Sequences of white space are preserved. Lines are only broken at newline characters in the source and at <br> elements.

pre-wrap

Sequences of white space are preserved. Lines are broken at newline characters, at <br>, and as necessary to fill line boxes.

pre-line

Sequences of white space are collapsed. Lines are broken at newline characters, at <br>, and as necessary to fill line boxes.

break-spaces

The behavior is identical to that of pre-wrap, except that:

Any sequence of preserved white space always takes up space, including at the end of the line.
A line-breaking opportunity exists after every preserved white space character, including between white space characters.
Such preserved spaces take up space and do not hang, thus affecting the box's intrinsic sizes (min-content size and max-content size).

The following table summarizes the behavior of the various 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
`nowrap`	Collapse	Collapse	No 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
`break-spaces`	Preserve	Preserve	Wrap	Wrap	Wrap

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.

Collapsing of white space

The white-space-collapse property page explains the browser algorithm for collapsing white space.

Controlling line wrapping in tables

HTML

html

<table>
  <tr>
    <td></td>
    <td>Very long content that splits</td>
    <td class="nw">Very long content that don't split</td>
  </tr>
  <tr>
    <td class="nw">white-space:</td>
    <td>normal</td>
    <td>nowrap</td>
  </tr>
</table>

CSS

css

table {
  border-collapse: collapse;
  border: solid black 1px;
  width: 250px;
  height: 150px;
}
td {
  border: solid 1px black;
  text-align: center;
}
.nw {
  white-space: nowrap;
}

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;
}
