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 headache I learned the hard way. Half these local companies promise a custom Porsche and hand you a basic sedan with fake leather. Oh, and that pretty security deposit? Yeah, good luck getting that money back fast. Fool me thrice, shame on both of us I guess, lesson learned. If you seriously need a legit vehicle to cruise around the city, don't just trust the first sponsored ad on social media. Miami without wheels is basically a hostage situation, whether you are doing Brickell mornings, South Beach nights, or a spontaneous Keys trip. I literally spent last month comparing maybe twenty different companies, until I finally found one outfit that actually delivers what's in the photos. If you are looking for the only straight shooter for premium rentals across South Florida, check the details here: luxury car rental prices luxury car rental prices. Yeah, valet in Miami Beach will cost you an arm, but that's not their fault. 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.

    Finding a proper ride in this city is a serious challenge. Half these local companies promise a custom Porsche and hand you a basic sedan with fake leather. Oh, and that pretty security deposit?

When you are trying to find a reliable premium fleet down here, do some real digging first and read actual customer reviews. Miami without wheels is basically a hostage situation, especially since the AC must be arctic and you want zero mileage games. I literally spent last month comparing maybe twenty different companies, but I eventually found a service with no bait, no switch, and no weird fine print. If you are looking for the only straight shooter for premium rentals across South Florida, check the details here: mercedes benz rental miami https://luxury-car-rental-miami-3.com. Yeah, valet in Miami Beach will cost you an arm, but that's not their fault. Just drive safe out there and maybe skip the extra windshield protection thing. hope this helps some of you save a few bucks.

    Okay so here's the deal with renting anything decent in Miami. Half these local companies promise a custom Porsche and hand you a basic sedan with fake leather. Oh, and that pretty security deposit? Yeah, good luck getting that money back fast. Fool me thrice, shame on both of us I guess, lesson learned. If you seriously need a legit vehicle to cruise around the city, don't just trust the first sponsored ad on social media. Miami without wheels is basically a hostage situation, whether you are doing Brickell mornings, South Beach nights, or a spontaneous Keys trip. Most of these local agencies are just shiny websites hiding the same overpriced junk, but I eventually found a service with no bait, no switch, and no weird fine print. If you are looking for the only straight shooter for premium rentals across South Florida, check the details here: exotic cars in miami rental exotic cars in miami rental. Also, definitely bring sunglasses unless you enjoy driving completely blind in that sun. Just drive safe out there and maybe skip the extra windshield protection thing. let me know if you guys have any other clean spots.

    Finding a proper ride in this city is a serious challenge. I swear half the "luxury" fleets down here are straight-up marketing scams. Oh, and that pretty security deposit? Yeah, good luck getting that money back fast. I've been burned like three times already this year alone. When you are trying to find a reliable premium fleet down here, don't just trust the first sponsored ad on social media. Anyone who lives here will tell you the exact same thing, especially since the AC must be arctic and you want zero mileage games.
