Une présentation du langage HTML agrémentée de nombreux exemples La langage HTML (HyperText Markup Language) est utilisé pour décrire la structure d'une page Web. C'est un langage descriptif à base de marqueurs (de tags, en anglais). Parfois, le terme de balise est aussi utilisé en lieu et place de marqueur. Le langage HTML est utilisé conjointement avec les langages CSS et Javascript.

Et comment les styler pour qu'elles ressemblent à des tableaux, des galeries d'images, des calendriers, etc. Les listes de définitions, qu'est-ce que c'est ?

Les balises h1 multiples autorisées en HTML5 C'est suite à plusieurs conversations m'invitant à ne pas utiliser de multiples balises h1 dans mes intégrations HTML (et plus récemment une demande « insistante » sur le fait de ne pas le faire) que je me vois forcé de marcher sur les pas de Raphaël Goetter -qui avait déjà abordé le sujet- pour expliquer pourquoi : en plus d'être tout à fait valide, cette pratique est bénéfique. Tout document HTML5 dispose de cloison de contenu (Sectionneur de contenu) que sont article, aside, nav et section. Ces zones de contenu peuvent chacune contenir une balise header et footer (ne cloisonnant pas elles-mêmes le contenu) et de multiple éléments de titrage (Titre en HTML) allant de h1 à h6. Bien que l'utilisation de plus d'une balise h1 ai pu rationnellement laisser à débattre (même si techniquement les standards ne l'interdise pas), les recommandations et même l'interdiction d'une telle pratique ne sont plus pertinentes et rationnelles à l'heure du HTML5. La balise h1 et les balises entêtes h2-h6
