Awesome thank you @dcapillae ! There are a few failures in the html validation for these tranlsations:

Ah which translations are missing </i> ? I can fix those!

We should create a new issue for the TITLE one ; for now, leave TITLE but translate the rest 👍

[dcapillae]

There are three strings that are missing the closing </i> code in the message.pot file, the strings starting with For example: <i> (lines 2864, 2875, 2886, 2897). I did not add it to the translation because they are also missing in the .pot file and I preferred to leave it the same so as not to break anything.

These are the translations that have not passed HTML validation, the translation strings starting with Por ejemplo: <i> (lines 3059, 3073, 3087, 3101) in the Spanish message.po file.

Ok I fixed most of these in #9214 ; there's still one erroring which I'm investigating 👍

[cdrini]

Ok this should be the last of them!
