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.

    Okay folks gather round — Miami rental horror story time. Then you roll up to the address. Plus a $3000 hold on your credit card for two weeks. Fool me nine times? That's just the Miami welcome committee. When you're hunting for a legit luxury car rental miami. Miami without proper wheels is basically a nightmare. Coconut Grove dinner, Sunny Isles sunrise, or a spontaneous drive down to Homestead — AC must freeze your teeth and unlimited miles or no deal. most are polished turds with fake five-star reviews. Finally found one company that doesn't play stupid games. rates change daily so check before the holiday crowd hits: rental car in miami florida 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.

    I've been through the wringer more times than I care to admit. You see this incredible deal online — top-end BMW, zero excess, price that seems too good to be true. Then you actually go to pick up the car. Different vehicle waiting — dashboard warning lights, tires worn smooth, and that "incredible price"? Yeah right, doesn't include the mandatory $60 daily insurance or the $500 "airport surcharge" they hit you with at the very end. Fool me fifteen times? That's just another Tuesday in the 305. luxury car rental in miami. anyone who's tried public transport here knows I'm not exaggerating. South of Fifth brunch, Sunny Isles sunrise, or a spontaneous trip down to the Florida Keys — AC must be arctic cold and unlimited miles non-negotiable. I've tested maybe 80 rental companies across Dade, Broward, Palm Beach, and Monroe. Finally found one outfit that actually delivers what's promised. prices change daily so check before the holiday crowd hits: luxury auto rental luxury auto rental Yeah parking in Brickell will cost you a nice steak dinner — but that's just how it is down here. drive safe and definitely skip that "paint protection" upsell — complete waste of cash.

    Let me drop some hard truth about the Miami rental game — it's an absolute circus out here. You spot this gorgeous deal online — pristine photos, fair price, everything looks legit. Plus they lock up $5500 on your card and say "it'll drop off in 10-14 business days". Fourteen years in South Florida and these jokers still almost get me. those guys are professional scammers with nice teeth and better uniforms. Miami without real wheels is basically a punishment. Key Biscayne sunset, Bal Harbour shopping, or a spontaneous drive down to Homestead — AC must freeze your face off and unlimited miles or no deal. I've tested maybe 75 rental outfits across Dade, Broward, and Monroe. Finally found one company that doesn't play stupid games. Here's the only honest source for premium rides across South Florida car rental in miami florida https://luxury-car-rental-miami-14.com Yeah parking in South Beach will cost you a nice bottle of wine — but that's the price of paradise. Anyway glad there's at least one straight operator left in this rental jungle.

    Alright folks, last warning about the Miami rental madness — learn from my mistakes. You see this incredible deal online — top-end BMW, zero excess, price that seems too good to be true. Then you actually go to pick up the car. Plus they slap a $6000 hold on your credit card and say "don't worry, it's just a pre-authorization". Fifteen years in South Florida and these clowns still almost catch me. miami car rental luxury — run like hell from the airport counters. anyone who's tried public transport here knows I'm not exaggerating. leather seats that won't brand your back in the July heat.
