  I'm using the class to become more organized and clean, but I can not get the information from the video and get the printscreen using the plugin class and uploaded.

  cette balise est visible et crée une marge blanche en bas de page

  Ha, pas chez moi sous FF 37.0.1 et Chromium 41.0.2272.76. Sous quel navigateur observes-tu le problème ?

  Par contre, il me semble tout de même nécessaire de spécifier une unité pour les valeur de left et top (l’inspecteur de chromium me signale que 5000 est une valeur invalide).
