<meta name="assert" content="In this test, the inline size of the orthogonal block is 'auto' and its containing block's block size is '400px'. Since the width (inline-size) of the containing block is definite in this test, then the constrain is the width (inline-size) of such containing block which is, in this test, 400px. But the min-content inline size of the orthogonal block is greater than the width (inline-size) of the containing block. Therefore, the min-content inline-size will become the width of the orthogonal block." />

shrink-to-fit formula min(max-content, max(min-content, constraint))
|
|
|
|
max-content inline size: narrowest inline size needed to fit its contents
|
|
if none of the soft wrap opportunities within the box were taken. Eg:
|
|
max-content of "I am a text sentence." is "I am a text sentence."

https://www.w3.org/TR/css-sizing-3/#max-content-inline-size
|
|
|
|
min-content inline size of the box: longest word in a sentence or longest non-breakable
|
|
inline box (inline replaced or inline-block). Eg: min-content of "I am a text sentence."
|
|
is "sentence."
|
|
https://www.w3.org/TR/css-sizing-3/#min-content-inline-size
|
|
|
|
contraint: min(available space, initial containing block's size)
|
|
|
|
available space: this is either a measurement of its containing block
|
|
(if that is definite) or an infinite size (when it is indefinite).

Inside this batch of 24 sizing-orthog-htb-in-vlr tests:
|
|
001-012 : body has 100px margin-left and 100px margin-right
|
|
013-024 : body has no horizontal margins
|
|
|
|
Inside each sub-batch of 12 tests:
|
|
001-006: containing block's width is 'auto' therefore indefinite
|
|
007-012: containing block's width is 400px therefore definite
|
|
|
|
Inside each sub-sub-batch of 6 tests:
|
|
001-003: containing block has 1 sentence before and after
|
|
004-006: containing block has no sentence before and no sentence after
|
|
|
|
Inside each sub-sub-sub-batch of 3 tests:
|
|
001: orthogonal block's width is 'auto'
|
|
002: orthogonal block's width is 'auto' and its min-content
|
|
inline size (1 very long word) is wider than constraint
|
|
003: orthogonal block's width is 'auto' its max-content inline-size
|
|
is narrower than max(min-content, constraint)
