"The baseline of an 'inline-table' is the baseline of the first row of the table." Related to #867.
|
I've fixed the position of superscript. The problem was caused by the wrong position of inline table's baseline. We now have to fix square root symbols and the circumflex position. |
|
The circumflex position is OK now. Lines larger than their parents were horizontally aligned, but it's not allowed by the spec. |
|
I think that everything's OK now. the first page of your updated sample looks the same between my browsers and WeasyPrint. The ones with inline The bugs closed thanks to this issue are corner cases of rarely used features, it was cool to fix them:
Thanks a lot for this bug report and for the samples, it was hard to debug but quite simple to fix. It's really good news to have this kind of bugs on rarely used features, as we blindly have to follow what the spec tells and see the result work like a charm. It makes me believe that the rest of the code is quite OK 😄. |

Wonderful to hear, thank you very much for the fixes. |

As recommended by @liZe in #59 I'm opening a separate issue to fix the rendering of this test page: https://gist.github.com/mbarkhau/ff263164cd162ff1fd734c2b0ce23241
The output is generated by KaTeX on Node.js, so JavaScript is not required to render the formulas, only HTML and CSS.
Running this file through WeasyPrint produces some warnings, but I would ignore those for this issue, as I was able to comment them out locally without affecting the rendering.
The text was updated successfully, but these errors were encountered:
