Description

HTML signifie : Hypertext Markup Language

Le langage HTML est constitué :

- de balises (tags en anglais)

- d'attributs (attributes)

- d'éléments (ce qui se trouve entre la balise ouvrante < et la balise fermante >).

Structure d'une page Web

Une page HTML est constituée au minimum :

- du doctype (pour indiquer au navigateur que le document est de type HTML)

- des balises qui elles-mêmen renferment 2 autres balises : et : ces 3 balises  sont les balises de premier niveau.

La section Head

La balise head renferme plusieurs balises qui sont interprétées par le navigateur, mais dont le contenu n'est pas affiché sur la page.

La section Head contient de nombreuses balises, parmi lesquelles nous trouvons : l'encodage de la page (le plus souvent UTF-8), le titre de la page (balise title) . On y trouve également des balises meta, des liens vers des feuilles de style CSS, et parfois des scripts en Javascript.

Les différentes balises meta et title jouent un rôle primordial pour le référencement.

La section Body

Elle contient au contraire tout ce qui sera affiché sur la page web dans le navigateur. Il existe de nombreux types de balises :

- les balises sectionnantes (permettant de diviser la page en plusieurs sections, comme header, nav, section, footer, article. Elles sont primordiales car elles donnent des indicationx aux moteurs de recherche qui parcourent les pages web).

- les balises de structuration du texte (comme les headings, les blockquotes, les paragraphes)

- les balises de listes (numérotées ou non)

- les balises de tableau (désormais déconseillées pour construire une page web, mais parfois très utiles pour construire le template d'une newsletter)

- les balises de formulaire (form, input, textarea...)

- les balises génériques (div, span...)

Mode d'affichage des éléments HTML

Il existe également une autre façon de distinguer certains types de balises.

On parle parfois en effet de :

- balises "inline" qui permettent de définir l'affichage d'un élément sans retour à la ligne. Parmi les balises inline, nous avons par exemple les balises  span, a, strong, img ...

- balises "blocks": elles occupent toute la largeur disponibles. Lorsque 2 éléments de type "blocks" se suivent, ils sont disposés par défaut l'un en dessous de l'autre. Nous avons par exemple les balises div, h1, p, ul, form, table, blockquote.

-de balises "invisibles" : elles ne s'affichent pas sur la page, comme par exemple la balise meta, inclue dans la partie head de la page.

Fonctionnalités
HTML permet d'écrire de l'hypertexte. Il permet de structurer sémantiquement et logiquement le contenu des pages web, mais aussi d'inclure des éléments multimédia tels que des images ou des vidéos.

Aux dernières nouvelles
Actuellement, la dernière version du HTML est le HTML 5. Mais les membres du groupe de travail du W3C veulent créer un HTML Living Standard, une version du HTML qui n'aurait pas de numéro de version. Ainsi le HTML serait en constante évolution.
