| <meta name="assert" content="In this test, the inline size of the orthogonal block is 'auto' and its containing block's block size is also 'auto'. Since the width of the containing block is indefinite in this test, then constrain is the width of initial containing block which is, in this test, equal to the width of the viewport." /> |

| <!-- |
| |
| shrink-to-fit formula is: 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) |
