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.

I've got the scars to prove it, the rental landscape down here is crazy. Then you show up at the local lot to pick up the car. Plus they freeze a surprise $2500 on your card for a week right before giving you the keys. Eight 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, run far from the airport counters. Miami without decent wheels is basically a hostage situation, especially since the AC must be arctic cold and unlimited miles non-negotiable. I've run through maybe 45 rental companies across Dade, Broward, and Monroe, but I eventually found a service where what you book is exactly what shows up, no surprises, no fine print nightmares. If you are looking for the only honest source for premium wheels across South Florida, check the current details here: mercedes for rent near me https://luxury-car-rental-miami-8.com. Also, definitely bring serious shades unless you enjoy driving straight into the sun like a zombie every single evening. Just drive safe out there and absolutely skip that "windshield protection" upsell — pure profit for them, zero value for you. let me know if you guys have any other clean spots.

I've got the scars to prove it, the rental landscape down here is crazy. Then you show up at the local lot to pick up the car. Different car waiting — scratches everywhere, smells like an ashtray, and that "amazing price"? Doesn't include the mandatory $400 cleaning fee or the $30 per day toll pass you can't waive. Eight years in South Florida and these clowns still almost get me. When you need a proper and reliable premium ride to cruise around, run far from the airport counters. Miami without decent wheels is basically a hostage situation, especially since the AC must be arctic cold and unlimited miles non-negotiable. Most of these local agencies are just shiny websites hiding the same beat-up fleet with fake reviews, but I eventually found a service where what you book is exactly what shows up, no surprises, no fine print nightmares. If you are looking for the only honest source for premium wheels across South Florida, check the current details here: rent urus miami rent urus miami.

Telefonuma 1xbet yüklemek istiyordum uzun süredir. Herkes farklı bir şey söylüyordu kime güveneceğimi şaşırdım. Güncel bilgileri kontrol edip süreci hatasız başlattım. En sonunda güvendiğim bir kaynağa ulaştım ve size de tüm detayları aktarmak istedim, güncel bilgilere buradan bakabilirsiniz: 1xbet nouvelle version à télécharger 1xbet nouvelle version à télécharger. Valla bak net söyleyeyim — telefonuma indirdikten sonra çok memnun kaldım. kurulumu da oldukça basitti yani rahat olun. Kendi deneyimlerimi aktarıyorum size — en hızlı uygulama bu oldu artık. Şimdiden iyi şanslar ve bol kazançlar...

Android için doğru sürümü bulmak gerçekten zordu. Play Store'da arattım ama bulamadım resmi olanı. Güncel bilgileri kontrol edip süreci hatasız başlattım. En sonunda güvendiğim bir kaynağa ulaştım ve size de tüm detayları aktarmak istedim, güncel bilgilere buradan bakabilirsiniz: 1xbet yükle 1xbet yükle. Yani anlatmak istediğim şu — mobil uygulaması inanılmaz kullanışlı çalışıyor. güncellemeleri de otomatik geliyor. Birçok platform denedim ama en iyisi bu çıktı — kesinlikle pişman olmazsınız deneyin derim. Şimdiden iyi şanslar ve bol kazançlar...
