Avoiding common HTML5 mistakes Between curating sites for the HTML5 gallery and answering readers’ questions here at HTML5 Doctor, I see a host of HTML5 sites and their underlying markup. In this post, I’ll show you some of the mistakes and poor markup practices I often see and explain how to avoid them. Don’t use section as a wrapper for styling One of the most common problems I see in people’s markup is the arbitrary replacement of <div>s with HTML5 sectioning elements — specifically, replacing wrapper <div>s (used for styling) with <section>s. In XHTML or HTML4, I would see something like this: <! Now, I’m instead seeing this: <! Frankly, that’s just wrong: <section> is not a wrapper. With that in mind, here’s the correct way to mark up the above example using HTML5 and a couple of ARIA roles. <body> <header> <h1>My super duper page</h1> <! If you’re not quite sure which element to use, then I suggest you refer to our HTML5 sectioning content element flowchart to guide you along your way. Ah, <figure>. <! Summary
CSS3 properties explained | css3files.com Seriously, What is HTML5? I’m tired of people getting confused. The W3C hasn’t done the best job at explaining what HTML5 is or means to a lot of people either. In fact, they went out of their way to say that, accompanying the HTML5 new branding, CSS3 and the JS API’s ( Geolocation, Websockets etc.), that are floating around with their own specs, are lumped into one and the same. So what is HTML5? First off, HTML5 ! Secondly, HTML5 ! So, what is HTML5? HTML5 is HTML. So why is HTML5 important? Well, if you have just become a web developer in the past 2-3 years you won’t remember the dark times we had before then. So what’s HTML5 look like? I get asked this a lot and the best way to answer is to point them to Paul Irish’s HTML5 Boilerplate (found here: ). <! If you’ve seen HTML before this shouldn’t look too different. Wrapping it up If you’re still confused then you need to dig deeper or just remember HTML5 === HTML. Note: Send your marketing friends to these W3C specs too.
La structure d’une page HTML5 Comme l’HTML5 est actuellement mis en œuvre par quasiment tous les webmasters sur Internet, enfin du moins les plus « passionnés », j’ai pensé qu’il était nécessaire d’expliquer certains des nouveaux éléments et de poser les bases de la structure d’une page HTML5. D’autant que plusieurs des sites que j’ai davantage regardés et qui montrent une structure HTML5, ne semblent pas avoir compris comment les nouveaux éléments structurels doivent être utilisés. Effectivement la structure de base d’un document HTML5 n’a pas changé. Chaque structure comprend une section d’entête (head) contenant des détails invisibles et des liens vers des ressources et une section de corps (body) où les éléments visibles du document résident. Voici un exemple pour la section d’entête (head) d’une page HTML5 : [sourcecode language="HTML"] <title>Titre de la page</title> </head> [/sourcecode] DOCTYPE (doctype) Élément HTML (html) Nous avons maintenant besoin d’ouvrir l’élément <html lang="fr">. Élément d’entête (head)
A Complete Guide to the Table Element The <table> element in HTML is used for displaying tabular data. You can think of it as a way to describe and display data that would make sense in spreadsheet software. Essentially: columns and rows. In this article we're going to look at how to use them, when to use them, and everything else you need to know. A Very Basic Example Here's a very simple demo of tabular data: It is data that is useful across multiple axis. Head and Body One thing we didn't do in the very basic example above is semantically indicate that the first row was the header of the table. That HTML would be like this: When you use <thead>, there must be no <tr> that is a direct child of <table>. Foot Along with <thead> and <tbody> there is <tfoot> for wrapping table rows that indicate the footer of the table. What is unique about <tfoot> is the placement in the HTML. Despite coming first in the source order, <tfoot> does indeed render at the bottom of the table, making it a rather unusual HTML element. Basic Styling Then:
The history of the Web - Web Education Community Group Introduction Where shall I begin, please your Majesty? Begin at the beginning, the King said gravely, and go on till you come to the end: then stop. Everything has to begin somewhere, so lets start with a focused history lesson. If any terms are unfamiliar to you, don’t worry: if they’re important for learning web development they’ll be defined in the later articles that go into more depth on each subject, and you can always search them out using your search engine of choice! The Internet’s origins On the fourth of October in 1957 an event occurred that would change the world. This event lead directly to the creation of the US Department of Defence, ARPA, due to a recognised need for an organisation that could research and develop advanced ideas and technology. In 1960, psychologist and computer scientist Joseph Licklider published a paper entitled Man-Computer Symbiosis, which articulated the idea of networked computers providing advanced information storage and retrieval.

The Power of HTML 5 and CSS 3 Web designers can do some pretty cool stuff with HTML 4 and CSS 2.1. We can structure our documents logically and create information-rich sites without relying on archaic, table-based layouts. We can style our web pages with beauty and detail without resorting to inline <font> and <br> tags. Indeed, our current design methods have taken us far beyond the hellish era of browser wars, proprietary protocols, and those hideous flashing, scrolling, and blinking web pages. As far as we’ve come using HTML 4 and CSS 2.1, however, we can do better. Goodbye <div> soup, hello semantic markup In the past, designers wrestled with semantically incorrect table-based layouts. <div id="news"><div class="section"><div class="article"><div class="header"><h1>Div Soup Demonstration</h1><p>Posted on July 11th, 2009</p></div><div class="content"><p>Lorem ipsum text blah blah blah. As you can see, HTML 5 enables us to replace our multitude of <div>s with semantically meaningful structural elements.

In conforming documents, there is only one body element. 4.3.2 The article <!
All HTML Tags - HTML5 tutorials Below is a list of all html tags with links to their page on this site, W3C.org and www.w3schools.com. W3C is the principle organization that sets standards for HTML. While I like what they are doing with HTML5, W3C's site is next to impossible to navigate and their language tangled at best. However, they are the powers that be. As a web designer you will eventually find yourself on their site. You may as well start now. I often use W3schools as a reference site, plus they have good intermediate level tutorials. Below I have links to the appropriate page on this site, on W3C and w3schools. Below you see elements in grey, red and pink. Elements in grey are in previous versions of HTML, but are not supported in HTML5. 1 Elements in red are new to HTML5 and have broad browser support. Elements in pink are new to HTML5, but don't yet have broad browser support. The tags:
