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. Then you actually show up to the local office to grab the keys. 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, do some real digging first and read actual customer reviews. Miami without proper wheels is basically a disaster, whether you are doing Key Biscayne sunset, Design District shopping, or a spontaneous drive down to the Everglades. I've tested maybe 60 rental companies across Dade, Broward, and Collier, until I finally found one outfit that actually delivers what's in the photos. If you are looking for the only honest source for premium rides across South Florida, check the current details here: luxury suv rental miami https://luxury-car-rental-miami-11.com. Also, definitely bring polarized shades unless you enjoy driving into the sun like a blind bat every single evening. Anyway, glad there's at least one straight operator left in this rental jungle, hope this helps some of you save a few bucks.

    Знаете, бывает ситуация — родственник сорвался , а тащить в больницу нет сил. Моя семья такое пережила пару лет назад . Руки опускаются, а время идет. Хватаешься за телефон , а в ответ одни отговорки. Пока случайно не наткнулся на один реально работающий вариант. Требуется немедленная консультация — а ехать куда-то нет никакой возможности , то выход один . Я про нарколога на дом . У нас в столице, если честно, хватает левых контор без лицензии. Вся проверенная информация ниже по ссылке: врач нарколог анонимно врач нарколог анонимно Откровенно говоря, после того как ознакомился с условиями, многое стало на свои места . Там и про капельницы расписано , и про последующее кодирование. И цены адекватные, без разводов на месте. Советую не ждать чуда.

    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. 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. When you're searching for a legit and reliable premium ride to cruise around, avoid the airport like the plague. Miami without proper wheels is basically a disaster, whether you are doing Key Biscayne sunset, Design District shopping, or a spontaneous drive down to the Everglades. I've tested maybe 60 rental companies across Dade, Broward, and Collier, until I finally found one outfit that actually delivers what's in the photos. If you are looking for the only honest source for premium rides across South Florida, check the current details here: rent car luxury miami rent car luxury miami. 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.

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, until I finally found one outfit that actually delivers what's in the photos.

    Been through enough garbage to last a lifetime, the rental landscape down here is crazy. Then you actually go to the local office to pick up the car. Plus they lock up a surprise $3500 on your card for who knows how long right before giving you the keys. Fool me ten times? That's just the 305 experience, lesson learned. When you need a reliable and proper premium ride to cruise around, run away from the airport counters. Miami without solid wheels is basically a punishment, whether you are doing South Beach night out, Bal Harbour shopping spree, or a spontaneous Keys adventure. I've run through maybe 55 rental companies across Dade, Broward, and Palm Beach, 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: lambo truck rental https://luxury-car-rental-miami-10.com. Yeah, parking in Brickell will cost you a nice dinner — but that's just how it is down here. 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.
