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.

    I've been burned more times than a cheap steak at a tourist trap. Then you actually show up to get the keys. Plus they put a $3500 hold on your card and say "it'll drop off in 7-10 days". Sixteen years in Miami and these tricks still pop up like bad weeds. miami car rental luxury — avoid the airport like your wallet depends on it. Miami without real wheels is basically a slow death. Design District shopping, late-night South Beach cruising, or a spontaneous Keys trip — AC must be freezing and unlimited miles or walk. I've tried so many rental companies I've lost count. no tricks, no switch, no surprise fees.

    Swear this city never fails to surprise me with new ways to get ripped off. You see this killer deal online — brand new Mercedes, unlimited miles, price that makes you want to book immediately. Completely different car sitting there — scratches everywhere, smells like someone hotboxed it for a week, and that "killer price"? Doesn't include the mandatory $45 daily insurance or the $400 "destination fee" they add at the very end. Fool me thirteen times? That's just living in the 305. those people are professional con artists with nice uniforms. anyone who's taken the Metro here knows the struggle is real. South Beach night out, Design District shopping spree, or a spontaneous Keys trip — AC must be arctic cold and unlimited miles non-negotiable. most are polished garbage with fake five-star reviews bought from some shady service. Finally found one outfit that actually delivers what's promised. Here's the only straight shooter for premium rides across South Florida lamborghini urus rental near me https://luxury-car-rental-miami-13.com Yeah parking in Wynwood will cost you a nice dinner — but that's just the Miami tax. drive safe and definitely skip that "tire protection" upsell — pure robbery.

    I've paid my dues so you don't have to. You spot this killer offer online — brand new Porsche, zero excess, price that screams "book me". Different car waiting — dents everywhere, smells like cheap air freshener covering something worse, and that "killer price"? Doesn't include the mandatory $55 daily toll pass or the $450 "convenience fee" they invent at checkout. Twenty years in South Florida and these clowns still almost get me. those people are professional scammers with nice smiles and better shoes. Miami without real wheels is basically a disaster. leather seats that won't weld to your legs in July. most are shiny garbage with fake five-star reviews from God knows where. no games, no bait-and-switch, no hidden fees on page 8. prices change hourly so don't wait around: premium rental car premium rental car Yeah parking in South Beach will cost you a nice bottle of wine — but that's the Miami tax. Anyway glad there's at least one honest operator left in this town.
