HTML 5 and CSS 3: The Techniques You’ll Soon Be Using In this tutorial, we are going to build a blog page using next-generation techniques from HTML 5 and CSS 3. The tutorial aims to demonstrate how we will be building websites when the specifications are finalized and the browser vendors have implemented them. If you already know HTML and CSS, it should be easy to follow along. Before we get started, consider using one of our HTML5 Templates or CSS Themes for your next project—that is, if you need a quick and professional solution. Otherwise, it's time to dig into these techniques. HTML 5 is the next major version of HTML. Before we begin marking up the page we should get the overall structure straight: In HTML 5 there are specific tags meant for marking up the header, navigation, sidebar and footer. It still looks like HTML markup, but there are a few things to note: In HTML 5, there is only one doctype. Instead of using divs to contain different sections of the page we are now using appropriate, semantic tags. "What?! That's all!
HTML5 differences from HTML4 Abstract HTML is the core language of the World Wide Web. The W3C publishes HTML5 and HTML5.1.

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
The Current State of HTML5 Forms · Wufoo The Introduction HTML5 is the newest specification for HTML, the language that web browsers read to display web pages. HTML5 has many new features intended to make creating websites easier and people's experience in using those websites better. Among those features are many enhancements to web forms. Support for HTML5 web form features is improving, but not all web browsers support HTML5 features the same way. The charts below list the most current version of each major browser. About Browser Versions In these charts, a version number like "4" means "the very first release of version 4 of this browser". JavaScript and HTML5 Forms Testing for Support If you intended to write JavaScript to mimic the functionality of HTML5 forms, you may want to first test the current browsers capability and write the JavaScript as a fallback. More accurate feature testing can be done through the excellent JavaScript library Modernizr. // Usage if (! Custom Validity Messages More JavaScript Fun CSS and HTML5 Forms
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:
HTML5 Encoding Secrets HTML5 Encoding Secrets After viewing this video, video publishers will have all the information they need to encode and stream to HTML5 browsers. Companies Mentioned: An hour is all a developer needs to begin working with MPEG4/H.264 and WebM video. That's the length of Jan Ozer's information-packed session How To: Encoding Video for HTML5 at the recent Streaming Media East conference in New York City. Presenting detailed information on both formats, as well as the codecs that drive them, Ozer gave viewers the knowledge they need to stream to HTML5 browsers. "One of the benefits, I think, of Google announcing WebM, is before they did there was some chance that we may have ended up paying for royalties for H.264 in 2015," said Ozer. "And then Google bought On2, the VP8 codec, then they open-sourced it, and right after Google open-sourced VP8 as WebM, MPEG LA said, 'No royalties ever on free Internet video.'
