Avoiding common HTML5 mistakes

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

HTML 5 Reference It is useful to make a distinction between the vocabulary of an HTML document—the elements and attributes, and their meanings—and the syntax in which it is written. HTML has a defined set of elements and attributes which can be used in a document; each designed for a specific purpose with their own meaning. Consider this set of elements to be analogous to the list of words in a dictionary. This includes elements for headings, paragraphs, lists, tables, links, form controls and many other features. This is the vocabulary of HTML. Designers: Learn To Code! Here's How To Start A friend, formerly a competitive fighter, once asked me: "Have you ever been punched in the face?" He and I were about to get in a bar fight. He needed to know if I could handle myself: Apparently, the fear of getting punched in the face holds you back from being effective in a fight.

You can think of it as a way to describe and display data that would make sense in spreadsheet software. Essentially: columns and rows.

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.

Sections and Outlines of an HTML5 Document - Web developer guide Note: The HTML5 outline algorithm as described below is not implemented in user agents, as a consequence, users who make use of heading semantics are exposed to the HTML 4 document structure. The description of problems solved by HTML5 is theoretical only. The HTML5 specification brings several new elements to web developers allowing them to describe the structure of a web document with standard semantics. This document describes these elements and how to use them to define the desired outline for any document. Structure of a Document in HTML 4 The structure of a document, i.e., the semantic structure of what is between <body> and </body>, is fundamental to presenting the page to the user.
