j'ai une barre de navigation fixe d'amorçage qui est pénétrant dans la barre de défilement pour une raison quelconque. Ce qui est bizarre, c'est que j'utilise ce code exact sur plusieurs pages et cela ne se prolonge que dans la barre de défilement de cette page en particulier. Des idées pourquoi cela se passerait-il?
