lock is 'auto' and its containing block's block size is '400px'. Since the width
of the containing block is definite in this test, then constrain is the width o
f such containing block which is, in this test, 400px. This test presumes that t
he initial containing block's width is greater than 400px. In this test, min-con
tent inline size (50ch) is greater than the width (400px) of the containing bloc
k. Therefore, the inline size of the orthogonal block will be the min-content in
line size." /> |

| 22 |
| 23 max-content inline size: narrowest inline size needed to fit its contents |
| 24 if none of the soft wrap opportunities within the box were taken. Eg: |
| 25 max-content of "I am a text sentence." is "I am a text sen
tence." |
| 26 https://www.w3.org/TR/css-sizing-3/#max-content-inline-size |
| 27 |
| 28 min-content inline size of the box: longest word in a sentence or longest non-
breakable |
| 29 inline box (inline replaced or inline-block). Eg: min-content of "I am a text
sentence." |
| 30 is "sentence." |
| 31 https://www.w3.org/TR/css-sizing-3/#min-content-inline-size |
| 32 |
| 33 contraint: min(available space, initial containing block's size) |
| 34 |
| 35 available space: this is either a measurement of its containing block |
| 36 (if that is definite) or an infinite size (when it is indefinite). |

| 41 Inside this batch of 24 sizing-orthog-htb-in-vrl tests: |
| 42 001-012 : body has 100px margin-left and 100px margin-right |
| 43 013-024 : body has no horizontal margins |
| 44 |
| 45 Inside each sub-batch of 12 tests: |
| 46 001-006: containing block's width is 'auto' therefore indefinite |
| 47 007-012: containing block's width is 400px therefore definite |
| 48 |
| 49 Inside each sub-sub-batch of 6 tests: |
| 50 001-003: containing block has 1 sentence before and after |
| 51 004-006: containing block has no sentence before and no sentence after |
| 52 |
| 53 Inside each sub-sub-sub-batch of 3 tests: |
| 54 001: orthogonal block's width is 'auto' |
| 55 002: orthogonal block's width is 'auto' and its min-content |
| 56 inline size (1 very long word) is wider than constraint |
| 57 003: orthogonal block's width is 'auto' and its max-content inline size |
| 58 is narrower than max(min-content, constraint) |
