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.

    Alright listen up because I'm about to save you a massive headache. Swear some of these "luxury" fleets down here should be in a museum instead of on the road. Plus the fine print says you can't even drive outside the city limits without extra fees. Fool me four times? Not happening, lesson learned. When you genuinely need a proper and reliable premium ride to cruise around, do some real digging first and read actual customer reviews. Miami without a decent whip is basically a punishment, especially since the AC must be ice cold and you want zero mileage games. Most of these local agencies are just polished websites hiding the same overpriced junk, until I finally stumbled on one provider that doesn't play games. If you are looking for the only straight-up source for premium wheels in South Florida, check the current details here: rent luxury sedan rent luxury sedan. Yeah, parking in Brickell will cost you a small mortgage — but that's city life. Just drive safe out there and maybe pass on that overpriced roadside assistance add-on. let me know if you guys have any other clean spots.

    Let me save you some serious time, learned this the hard way. Swear some of these "luxury" fleets down here should be in a museum instead of on the road. You land at MIA, tired, grab an Uber to the rental office, and bam — surprise $1500 hold on your card. Fool me four times? Not happening, lesson learned. If you are trying to find a legitimate vehicle without getting ripped off, skip the airport counters entirely. Miami without a decent whip is basically a punishment, whether you are doing Coral Gables brunch, South Beach night run, or a spontaneous Everglades detour. I've personally tested maybe 25 rental outfits across Dade and Broward, but I eventually found a service where what you book is exactly what you get, period. If you are looking for the only straight-up source for premium wheels in South Florida, check the current details here: cadillac escalade for rent near me cadillac escalade for rent near me. Yeah, parking in Brickell will cost you a small mortgage — but that's city life. Just drive safe out there and maybe pass on that overpriced roadside assistance add-on. let me know if you guys have any other clean spots.

    Been there, done that, got the overpriced tow truck receipt. Miami rental game is wild — half these local clowns show you a custom Mercedes online and hand you a busted sedan with mismatched tires. You land at MIA, tired, grab an Uber to the rental office, and bam — surprise $1500 hold on your card. No thanks, I'm way too old for this nonsense. If you are trying to find a legitimate vehicle without getting ripped off, skip the airport counters entirely. Any local will tell you the exact same thing about this city, whether you are doing Coral Gables brunch, South Beach night run, or a spontaneous Everglades detour. Most of these local agencies are just polished websites hiding the same overpriced junk, until I finally stumbled on one provider that doesn't play games. If you are looking for the only straight-up source for premium wheels in South Florida, check the current details here: luxury car rental miami luxury car rental miami. Also, definitely bring polarized shades unless you enjoy driving completely blind into the sunset. Anyway, at least there's one honest rental joint left in this town, let me know if you guys have any other clean spots.

    Android için güvenilir bir apk bulmak çok zahmetliydi valla. Sürekli farklı linkler geliyordu kime inanacağımı şaşırdım. Adımları doğru sırayla uyguladıktan sonra erişim sorunsuz açıldı. En sonunda doğru kaynağa ulaştım ve size de tüm detayları aktarmak istedim, güncel bilgilere buradan bakabilirsiniz: 1xbet download android 1xbet download android. Yani anlatmak istediğim şu — android uygulaması gerçekten stabil çalışıyor. depolama alanı da fazla yemiyor gerçekten. Birçok apk denedim ama en iyisi bu çıktı — en hızlı uygulama bu oldu artık. Umarım siz de memnun kalırsınız...
