white-space Attribute | whiteSpace Property

Sets or retrieves a value that indicates whether lines are automatically broken inside the object .

This property now applies to the currentStyle element. The pre value of this property is now supported.

Syntax

HTML Scripting

{ white-space : sWrap }

object.style.whiteSpace ( v ) [ = sWrap ]

Possible Values

sWrap

String that specifies or receives one of the following values.

normal	Default. Lines of text break automatically. Content wraps to the next line if it exceeds the width of the object.
nowrap	Line breaks are suppressed. Content does not wrap to the next line.
pre	Line breaks and other whitespace are preserved. This possible value is supported in Internet Explorer 6 and later when the !DOCTYPE declaration specifies standards-compliant mode. When the !DOCTYPE declaration does not specify standards-compliant mode, you can retrieve this value, but it does not affect rendering—it functions like the normal value.

The property is read/write for all objects except the following, for which it is read-only: currentStyle . The property has a default value of normal . The Cascading Style Sheets (CSS) attribute is inherited.

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties .

Remarks

Whitespace, such as line breaks, spaces, and tabs, is collapsed by default in HTML documents. You can use the nonbreaking space entity ( ) to add extra spaces to an object when the whiteSpace property is set to normal or nowrap . You can add extra line breaks using the br element.

This property affects content you access through the Document Object Model (DOM) the same way it affects the way Internet Explorer displays the content.

Examples

The following example shows how automatic line breaks are suppressed when the user places the mouse pointer over the paragraph. This is caused by toggling the value of the white-space attribute in the onmouseover and onmouseout events of the p element. When the white-space attribute is set to nowrap in the onmouseover event, line breaks are suppressed, and horizontal scrolling is required to view content wider than the element. When the attribute is set to normal in the onmouseout event, lines break automatically, depending on the width of the element.

<HTML>
<HEAD>
<STYLE>
.clsOneLiner { white-space : nowrap}
.clsAutoBreak { white-space : normal}
</STYLE>
</HEAD>
<BODY>
<P ONMOUSEOVER="this.className='clsOneLiner';" ONMOUSEOUT="this.className='clsAutoBreak';"> Long lines of text remain unbroken when the value of the whitespace attribute is set to nowrap. Place your mouse over the text to suppress automatic line breaks.</P>
</BODY>
</HTML>

The following example shows how to set and retrieve the value of the whiteSpace property. When the user sets the value of the whiteSpace property of a div element, the value of the property is retrieved in a span element.
