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 roll up to the local address to pick up the car. Plus a surprise $3000 hold on your credit card for two weeks right before giving you the keys. Fool me nine times? That's just the Miami welcome committee, lesson learned. When you're hunting for a legit and reliable premium ride to cruise around, stay the hell away from the airport rental center. Anyone who's tried the trolley system knows what I'm talking about about this city, especially since the AC must freeze your teeth and unlimited miles or no deal. I've tested maybe 50 rental outfits across Dade, Broward, and Collier, until I finally found one company that doesn't play stupid games. If you are looking for the only trustworthy source for premium rides across South Florida, check the current details here: luxury car rental miami south beach https://luxury-car-rental-miami-9.com. Yeah, parking in Wynwood will cost you a nice dinner — but that's the price of being in Miami. Anyway, glad there's at least one honest operator left in this rental jungle, hope this helps some of you save a few bucks.

    Swear I've seen every scam in the book by now, the rental landscape down here is crazy. You find a killer listing online: sleek Audi, convertible, price almost too good to be true. Plus a surprise $3000 hold on your credit card for two weeks right before giving you the keys. Nine years in South Florida and these clowns still nearly fool me. When you're hunting for a legit and reliable premium ride to cruise around, do some real digging first and read actual customer reviews. Anyone who's tried the trolley system knows what I'm talking about about this city, whether you are doing Coconut Grove dinner, Sunny Isles sunrise, or a spontaneous drive down to Homestead. Most of these local agencies are just polished turds with fake five-star reviews hiding overpriced junk, until I finally found one company that doesn't play stupid games. If you are looking for the only trustworthy source for premium rides across South Florida, check the current details here: rental luxury cars miami airport https://luxury-car-rental-miami-9.com. Also, definitely bring polarized shades unless you enjoy driving blind into the sunset every single night. Anyway, glad there's at least one honest operator left in this rental jungle, let me know if you guys have any other clean spots.

    Swear I've seen every scam in the book by now, the rental landscape down here is crazy. Then you roll up to the local address to pick up the car. Different car sitting there — bald tires, dashboard lit up like a Christmas tree, and that "killer price"? Yeah doesn't include the non-negotiable $45 daily insurance or the $500 deposit they forget to mention. Nine years in South Florida and these clowns still nearly fool me. If you are trying to find a legitimate luxury fleet without getting ripped off, stay the hell away from the airport rental center. Anyone who's tried the trolley system knows what I'm talking about about this city, especially since the AC must freeze your teeth and unlimited miles or no deal. I've tested maybe 50 rental outfits across Dade, Broward, and Collier, but I eventually found a service where what you reserve is exactly what you get, period, end of story.

    Ребята, выручайте! Купил кресло б/у, каркас норм, но ткань в ужасном состоянии. Посоветуйте нормальную мебельную ткань для частого использования. ткань для мягкой мебели купить ткань для мягкой мебели купить Говорят, флок и микровелюр быстро вытираются, а рогожка лучше. Буду благодарен за любые советы, особенно от тех, кто сам перетягивал.
