<p>Je trouve cette approche particulièrement pertinente, un peu difficile avec une <abbr title="Single Page App">SPA</abbr> sans serveur tout de même. Et encore, il y aurait des choses à expérimenter : on peut potentiellement aller très loin en CSS uniquement avec des <code>:checked</code> par exemple. À voir à quel point est-ce que ça endommage l’accessibilité par ailleurs… les défis techniques hypothétiques sont parfois de fausses bonnes idées pour des usages qui sont eux bien réels.</p> |

<p>Les tests utilisateur·ices sont une source intarissable de découvertes impensables. <em>Qu’il faut pourtant panser.</em></p> |
