Le Web est un système complexe. Certaines erreurs d'implémentation se propagent vite, les développeurs les utilisant. Les implémenteurs de clients Web (navigateurs inclus) doivent hacker pour coller à la réalité du Web tel que pratiqué. Nous verrons ensemble pourquoi les navigateurs implémentent parfois différement de ce que préconise le standard, comment les standards ont évolué pour être plus proches de la réalité et ce que les développeurs peuvent faire pour éviter que les bugs se propagent avec quelques techniques de développement.

Constantly asking for confirmation where the answer is almost always 
“yes” conditions the user to press “yes” without thinking about it, a
habit that can have very unfortunate consequences. Programs should
request confirmation only when there is good reason to suspect that the
answer might be “no no no!” A confirmation request that is not a
surprise is a strong hint of bad design. Any confirmation prompts at all
may be a sign that what your interface really needs is an undo command.
