Défis liés à l’interprétation des codes :

 HTML formatters rely on accurately interpreting the code structure, which can sometimes be challenging if the code contains unconventional or non-standard patterns. Code interpretation challenges can lead to incorrect formatting or unexpected behavior. It's crucial to evaluate these limitations and consider the requirements of your project before selecting an HTML formatter.

Considérations relatives à la protection de la vie privée et à la sécurité

When using HTML formatters, it's essential to consider privacy and security concerns. Here are some factors to consider.
