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.

娛樂城，通常指的是一個線上賭博平台，提供各種娛樂遊戲，如賭場遊戲、體育博彩、電子遊戲等。這些平台讓玩家可以在網路上進行賭博，而不需要親自前往實體賭場。娛樂城通常包含了各式各樣的遊戲選項，例如百家樂、輪盤、老虎機、撲克等，並且透過即時娛樂、直播等技術，提升了玩家的沉浸感和互動性。現今的娛樂城大多數已經支援手機和桌面端的多平台操作，讓玩家可以隨時隨地參與遊戲，這樣的便利性使得它們受到全球玩家的青睞。此外，娛樂城也會推出不同的優惠活動、註冊獎金和忠誠計劃，吸引新用戶並保持老用戶的活躍度。然而，娛樂城的風險也不可忽視。由於賭博本身具有高度的娛樂性，但也存在可能的成癮問題。多數國家對於線上賭博有著嚴格的法律規範，玩家在選擇娛樂城平台時，應該格外留意平台的合法性和安全性，以避免陷入詐騙或遭遇其他法律風險。因此，理性投注並了解相關法律是每位玩家應該保持的基本態度。

“You get some of me but not tomorrow as they want me in as soon as I can make it happen. This is the one time when they say jump and I ask how high due the financial gains the company could benefit from and it being important enough for the client to appear in person.” “Well I get an extra night of you at least! I wonder what we could do with that? Meantime, what about food? I am starving and delicious as it was a second breakfast is not quite enough to replenish me!” “Well get something on and we’ll sort that out first.” We drove into town and decided that a daytime visit to Charlie’s was going to be the answer. I parked in the bar lot and Elise dashed in to change into something more appropriate, jeans and a t-shirt along with her biker jacket but keeping her Converses on. Walking down to the restaurant was different from the middle of the night visits as the streets were bustling and all of the shops and outlets were open. Reaching Charlie’s we entered the front door and sat in a booth near the window. A beautiful young American Chinese girl came,smiled and said hello to Elise and gave us menus and asked if we wanted drinks in the meantime. "No thanks Lin just a pot of Jasmine tea for us please." Lin went back to the kitchen area. “No booze for me today as I will have to work in the bar so it is just tea for me.” Not in a drinking mood either, I agreed with her." https://www.hentai-foundry.com/user/lenardo19671989/profile https://terpka1961.diary.ru/ https://www.haikudeck.com/presentations/Wkltc19klP https://anotepad.com/notes/ibj5marc https://anotepad.com/notes/3mn5r6em
