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.

Vaping Culture in Singapore: A Lifestyle Beyond the Hype In today’s fast-paced world, people are always looking for ways to unwind, relax, and enjoy the moment — and for many, vaping has become an essential part of their routine . In Singapore, where modern life moves quickly, the rise of vaping culture has brought with it a fresh way to relax . It's not just about the devices or the clouds of vapor — it's about flavor, convenience, and finding your own vibe. Disposable Vapes: Simple, Smooth, Ready to Go Let’s face it — nobody wants to deal with complicated setups all the time. That’s where disposable vapes shine. They’re perfect for people on the move who still want that satisfying hit without the hassle of charging, refilling, or replacing parts. Popular models like the VAPETAPE UNPLUG / OFFGRID, LANA ULTRA II, and SNOWWOLF SMART HD offer thousands of puffs in one sleek little package . Whether you're out for the day or just need something quick and easy, these disposables have got your back. New Arrivals: Fresh Gear, Fresh Experience The best part about being into vaping? There’s always something new around the corner. The latest releases like the ELFBAR ICE KING and ALADDIN ENJOY PRO MAX bring something different to the table — whether it’s richer flavors . The ELFBAR RAYA D2 is another standout, offering more than just puff count — it comes with a built-in screen , so you can really make it your own. Bundles: Smart Choices for Regular Vapers If you vape often, buying in bulk just makes sense. Combo packs like the VAPETAPE OFFGRID COMBO or the LANA BAR 10 PCS COMBO aren’t just practical — they’re also a smart investment . No more running out at the worst time, and you save a bit while you're at it. Flavors That Speak to You At the end of the day, it’s all about taste. Some days you want something icy and refreshing from the Cold Series, other times you're craving the smooth, mellow vibes of the Smooth Series. Then there are those sweet cravings — and trust us, the Sweet Series delivers. Prefer the classic richness of tobacco? There’s a whole series for that too. And if you're trying to cut back on nicotine, the Zero-Nicotine Line gives you all the flavor without the buzz. Final Thoughts Vaping in Singapore isn’t just a passing trend — it’s a lifestyle choice for many. With so many options available, from pocket-sized disposables to customizable devices, there's something for everyone. Whether you're exploring vaping for the first time , or a seasoned vaper , the experience is all about what feels right to you — made personal for you.
