<display-outside>
keywords specify the element’s outer
display
type, which is essentially its role in flow layout. These keywords are used as values of the
display
property, and can be used for legacy purposes as a single keyword, or as defined in the Level 3 specification alongside a value from the
<display-inside>
keywords.
Valid
<display-outside>
values:
block
The element generates a block element box, generating line breaks both before and after the element when in the normal flow.
inline
The element generates one or more inline element boxes that do not generate line breaks before or after themselves. In normal flow, the next element will be on the same line if there is space
run-in
display: run-in
box is a block box, the
run-in
box becomes the first inline box of the block box that follows it.
注意
: Browsers that support the two value syntax, on finding the outer value only, such as when
display: block
or
display: inline
is specified, will set the inner value to
flow
. This will result in expected behavior; for example if you specify an element to be block, you would expect that the children of that element would participate in block and inline normal flow layout.
In the following example, span elements (normally displayed as inline elements) are set to
display: block
and so break onto new lines and expand to fill their container in the inline dimension.
<span>span 1</span> <span>span 2</span>
span {
display: block;
border: 1px solid rebeccapurple;
}
