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

HTML5 Cross Browser Polyfills · Modernizr/Modernizr Wiki The No-Nonsense Guide to HTML5 Fallbacks So here we're collecting all the shims, fallbacks, and polyfills in order to implant HTML5 functionality in browsers that don't natively support them. The general idea is that: We, as developers, should be able to develop with the HTML5 APIs, and scripts can create the methods and objects that should exist. Developing in this future-proof way means as users upgrade, your code doesn't have to change but users will move to the better, native experience cleanly.

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:

Content model: Flow content. Tag omission in text/html: A body element's start tag can be omitted if the element is empty, or if the first thing inside the body element is not a space character or a comment, except if the first thing inside the body element is a meta, link, script, style, or template element. A body element's end tag can be omitted if the body element is not immediately followed by a comment.

All HTML Tags - HTML5 tutorials Below is a list of all html tags with links to their page on this site, and 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:

User Agent Man — A Blog about Client Side Web Technology I am Zoltan "Du Lac" Hawryluk (and yes, Zoltan is my real name). I am web developer born and raised in Toronto, Canada.
