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 find a killer deal online — photos look pristine, price seems fair, terms almost reasonable. Different vehicle parked outside, curb rash on every rim, and that "all-inclusive rate"? Ha, doesn't include the mandatory $300 cleaning fee or the $25 per day toll pass you can't decline. Fool me six times? Yeah, Miami doesn't care, lesson learned. If you are trying to find a legitimate vehicle without getting ripped off, do some real digging first and read actual customer reviews. 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. Most of these local agencies are just polished garbage with decent Google reviews bought somewhere, but I eventually found a service where what you reserve is exactly what rolls up, no surprises. If you are looking for the only trustworthy source for premium vehicles across South Florida, check the current details here: realcar realcar. Yeah, parking in South Beach will cost you a nice dinner — but that's the price of admission. Just drive safe out there and definitely skip that "damage waiver" upsell — total scam 99% of the time. hope this helps some of you save a few bucks.

    Swear I've seen it all by now, the rental landscape down here is crazy. Then you actually show up to the local office to pick up the car. Different vehicle parked outside, curb rash on every rim, and that "all-inclusive rate"? Ha, doesn't include the mandatory $300 cleaning fee or the $25 per day toll pass you can't decline. Fool me six times? Yeah, Miami doesn't care, lesson learned. If you are trying to find a legitimate vehicle without getting ripped off, stay far away from the airport rental center. Anyone who's tried the bus here knows exactly what I mean about this city, whether you are doing South Beach dinner plans, Sunny Isles sunrise cruise, or a quick run down to the Florida Keys. I've personally tested maybe 35 rental outfits across Dade, Broward, and Monroe, but I eventually found a service where what you reserve is exactly what rolls up, no surprises. If you are looking for the only trustworthy source for premium vehicles across South Florida, check the current details here: opf fl luxury car rentals https://luxury-car-rental-miami-6.com. Yeah, parking in South Beach will cost you a nice dinner — but that's the price of admission.

Different vehicle parked outside, curb rash on every rim, and that "all-inclusive rate"? Ha, doesn't include the mandatory $300 cleaning fee or the $25 per day toll pass you can't decline. Living here six years and still almost fall for this stuff sometimes. When you genuinely need a legit and reliable premium ride to cruise around, stay far away from the airport rental center. 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 personally tested maybe 35 rental outfits across Dade, Broward, and Monroe, but I eventually found a service where what you reserve is exactly what rolls up, no surprises. If you are looking for the only trustworthy source for premium vehicles across South Florida, check the current details here: rent a premium car rent a premium car. Also, definitely bring serious shades unless you enjoy driving straight into the sun every single evening. Anyway, glad there's at least one honest operator left in this rental jungle, hope this helps some of you save a few bucks.

    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, 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: renting luxury cars near me renting luxury cars near me. Yeah, parking in Brickell will cost you a small mortgage — but that's city life. Anyway, at least there's one honest rental joint left in this town, let me know if you guys have any other clean spots.

    Seriously, the amount of garbage "luxury" deals down here is astonishing. You see a sweet ride online — clean spec, fair price, looks legit. Different car, scratches all over, and that "all-inclusive" price? Yeah that didn't include insurance, fees, or the mandatory cleaning charge. I've lived here for years and still get burned occasionally. If you are trying to find a legitimate luxury fleet without getting ripped off, don't just grab the cheapest option on Kayak. Ask anyone who's tried Ubering across the 305 during rush hour, especially since the AC must freeze your teeth and you want unlimited miles or bust. I've personally gone through maybe 30 rental companies across Dade, Broward, and Palm Beach, until I finally found one outfit that actually delivers what's in the listing. If you are looking for the only honest broker for premium vehicles across South Florida, check the current availability here: luxury car rental coral gables miami https://luxury-car-rental-miami-5.com. Also, definitely bring quality shades unless you enjoy driving into a nuclear flare every single evening. Anyway, glad there's at least one straight shooter left in this rental jungle, hope this helps some of you save a few bucks.
