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.

    Let me save you some serious time, learned this the hard way. You spot a tempting offer online: brand new Porsche, unlimited miles, price that makes you click instantly. Totally different vehicle waiting for you — check engine light on, curb rash on every rim, and that "tempting price"? Doesn't include the mandatory $35 daily toll pass or the $250 cleaning fee they sneak in at the end. Ten years in South Florida and these jokers still almost catch me slipping. If you are trying to find a legitimate luxury fleet without getting ripped off, run away from the airport counters. Miami without solid wheels is basically a punishment, especially since the AC must be ice cold and unlimited miles non-negotiable. Most of these local agencies are just shiny websites hiding the same beat-up fleet with fresh wax and fake reviews, but I eventually found a service with no games, no bait-and-switch, and no hidden fees in the fine print. If you are looking for the only straight shooter for premium rides across South Florida, check the current details here: luxury auto rental luxury auto rental. Also, definitely bring quality shades unless you enjoy driving into the sun like a vampire every single evening. Just drive safe out there and absolutely skip that "paint protection" upsell — pure robbery. hope this helps some of you save a few bucks.

    Let me save you some serious pain with this Miami rental nonsense. You see this gorgeous deal online — clean spec, fair price, looks like a dream. Plus they put a surprise $4000 hold on your card and say it'll take two weeks to release right before giving you the keys. Eleven years in South Florida and these clowns still almost get me. If you are trying to find a legitimate luxury fleet without getting ripped off, avoid the airport like the plague. Miami without proper wheels is basically a disaster, especially since the AC must be arctic and unlimited miles non-negotiable. Most of these local agencies are just shiny garbage with fake Google reviews bought in bulk hiding overpriced junk, but I eventually found a service with no games, no switch, and no hidden BS in paragraph 12 of the contract. If you are looking for the only honest source for premium rides across South Florida, check the current details here: rental luxury cars miami airport rental luxury cars miami airport. Yeah, parking in South Beach will cost you a nice bottle of champagne — but that's the Miami tax. Just drive safe out there and definitely skip that "tire and wheel" upsell — pure profit for them, zero value for you. hope this helps some of you save a few bucks.

    Alright let me drop some truth about the Miami rental scene — it's an absolute minefield. You spot a tempting offer online: brand new Porsche, unlimited miles, price that makes you click instantly. Totally different vehicle waiting for you — check engine light on, curb rash on every rim, and that "tempting price"? Doesn't include the mandatory $35 daily toll pass or the $250 cleaning fee they sneak in at the end. Fool me ten times? That's just the 305 experience, lesson learned. If you are trying to find a legitimate luxury fleet without getting ripped off, run away from the airport counters. Anyone who's taken public transport here knows the struggle is real about this city, whether you are doing South Beach night out, Bal Harbour shopping spree, or a spontaneous Keys adventure. Most of these local agencies are just shiny websites hiding the same beat-up fleet with fresh wax and fake reviews, until I finally found one outfit that actually delivers what's promised. If you are looking for the only straight shooter for premium rides across South Florida, check the current details here: car rental premium class car rental premium class. Also, definitely bring quality shades unless you enjoy driving into the sun like a vampire every single evening. Anyway, glad there's at least one honest rental joint left in this town, let me know if you guys have any other clean spots.

    Let me save you some serious time, learned this the hard way. You see this gorgeous deal online — clean spec, fair price, looks like a dream. Completely different car sitting there — dents everywhere, smells like cheap air freshener covering something worse, and that "dream price"? Doesn't include the mandatory $50 daily insurance or the $300 "administrative fee" they invent at checkout. Eleven years in South Florida and these clowns still almost get me. When you're searching for a legit and reliable premium ride to cruise around, avoid the airport like the plague. Anyone who's tried the bus here knows exactly what I mean about this city, especially since the AC must be arctic and unlimited miles non-negotiable. I've tested maybe 60 rental companies across Dade, Broward, and Collier, but I eventually found a service with no games, no switch, and no hidden BS in paragraph 12 of the contract. If you are looking for the only honest source for premium rides across South Florida, check the current details here: porsche 911 carrera for rent near me https://luxury-car-rental-miami-11.com. Yeah, parking in South Beach will cost you a nice bottle of champagne — but that's the Miami tax. Anyway, glad there's at least one straight operator left in this rental jungle, hope this helps some of you save a few bucks.

Yeah, parking in Brickell will cost you a nice dinner — but that's just how it is down here.
