Property values

Type: BSTR

normal (normal)

Default. Allows line breaking within words.

break-all (break-all)

Behaves as normal for CJK text, yet allows the line to break arbitrarily for non-CJK text. This value is suited to CJK text that contains small amounts of non-CJK text.

keep-all (keep-all)

Behaves as normal for non-CJK text, but disallows word breaking for CJK text. This value is suited to non-CJK text that includes small amounts of CJK text.

String format

normal | break-all | keep-all

Standards information

CSS Text Level 3, Section 5.2

Remarks

Windows Internet Explorer 8. The IHTMLRuleStyle2::wordBreak attribute is an extension to CSS, and can be used as a synonym for word-break in IE8 Standards mode.

When using the IHTMLRuleStyle2::wordBreak attribute with a table, you must set the IHTMLRuleStyle2::tableLayout attribute to fixed on the table.

The behaviors of the parameter values are detailed in CSS Text Level 3: W3C Working Draft (6 March 2007), sec. 4.1, "Line Breaking Restrictions: The 'word-break' Property"; and in Unicode Standard Annex #14: Line Breaking Properties.

Examples

The following example shows three div objects that each contain a paragraph of text.

<div class="normal">
   <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.</p>
</div>
<div class="break-all">
   <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.</p>
</div>
<div class="keep-all">
   <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.</p>
</div>

In the first div object, IHTMLRuleStyle2::wordBreak is set to the initial value, normal. This allows the text to break normally. In the second div object, IHTMLRuleStyle2::wordBreak is set to break-all. This allows CJK text to behave as normal but allows the line to break arbitrarily for non-CJK text. In the last div object, IHTMLRuleStyle2::wordBreak is set to keep-all. Because the text in the paragraph is non-CJK text, it behaves as normal.

div {
   background-color: #B0C4DE;
   width: 200px;
}
.normal {
   word-break: normal;
}
.break-all {
   word-break: break-all;
}
.keep-all {
   word-break: keep-all;
}
