Short Description goes here. too long for the margin Description goes here. This example might be formatted as: short Description goes here too long for the margin Description goes here The ’text-align’ property can be used to align the compact element inside the margin: against the left edge of the margin (’left’), against the right edge (’right’), or centered in the margin (’center’). The value ’justify’ doesn’t apply, and is handled as either ’left’ or ’right’, depending on the ’direction’ of the block-level element in whose margin the compact element is formatted. (’left’ if the direction is ’ltr’, ’right’ if it is ’rtl’.) Please consult the section on generated content [p. 156] for information about how compact boxes interact with generated content. 9.2.4 Run-in boxes A run-in box behaves as follows: If a block [p. 97] box (that does not float and is not absolutely positioned [p. 113] ) follows the run-in box, the run-in box becomes the first inline box of the block box. Otherwise, the run-in box becomes a block box. A ’run-in’ box is useful for run-in headers, as in this example: A run-in box example H3 { display: run-in } A run-in heading. And a paragraph of text that follows it. This example might be formatted as: A run-in heading. And a paragraph of text that follows it. 100
The properties of the run-in element are inherited from its parent in the source tree, not from the block box it visually becomes part of. Please consult the section on generated content [p. 156] for information about how run-in boxes interact with generated content. 9.2.5 The ’display’ property ’display’ Value: inline | block | list-item | run-in | compact | marker | table | inline-table | table-row-group | table-header-group | table-footer-group | table-row | table-column-group | table-column | table-cell | table-caption | none | inherit Initial: inline Applies to: all elements Inherited: no Percentages: N/A Media: all The values of this property have the following meanings: block This value causes an element to generate a principal block box. inline This value causes an element to generate one or more inline boxes. list-item This value causes an element (e.g., LI in HTML) to generate a principal block box and a list-item inline box. For information about lists and examples of list formatting, please consult the section on lists [p. 168] . marker This value declares generated content [p. 153] before or after a box to be a marker. This value should only be used with :before and :after pseudo-elements [p. 153] attached to block-level elements. In other cases, this value is interpreted as ’inline’. Please consult the section on markers [p. 164] for more information. none This value causes an element to generate no boxes in the formatting structure [p. 25] (i.e., the element has no effect on layout). Descendant elements do not generate any boxes either; this behavior cannot be overridden by setting the ’display’ property on the descendants. Please note that a display of ’none’ does not create an invisible box; it creates no box at all. CSS includes mechanisms that enable an element to generate boxes in the formatting structure that affect formatting but are not visible themselves. Please consult the section on visibility [p. 149] for details. run-in and compact These values create either block or inline boxes, depending on context. Properties apply to run-in and compact boxes based on their final status (inline-level or block-level). For example, the ’white-space’ property only applies if the box becomes a block box. 101
