Continuing our examination of HTML5, this time we’ll take a slightly deeper look at the state of HTML5 support in browsers. We’ll step through several major features, examine the technical hurdles in place, identify the level of browser support and finally provide some recommendations on whether or not to pull the trigger with that shiny new feature.
New Semantic Elements
HTML5 has added many new semantic elements. These both codify existing, common patterns and offer new, meaningful ways mark up your content. So, for example, going forward, instead of using <div id="header"> we will now just use <header>. Some other examples (with definitions culled from the specification) include:
section
The section element represents a generic document or application section. A section, in this context, is a thematic grouping of content, typically with a heading.
Examples of sections would be chapters, the various tabbed pages in a tabbed dialog box, or the numbered sections of a thesis. A Web site’s home page could be split into sections for an introduction, news items, contact information.
footer
The footer element represents a footer for its nearest ancestor sectioning content or sectioning root element. A footer typically contains information about its section such as who wrote it, links to related documents, copyright data, and the like.
nav
The nav element represents a section of a page that links to other pages or to parts within the page: a section with navigation links.
article
The article element represents a component of a page that consists of a self-contained composition in a document, page, application, or site and that is intended to be independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.
That’s far from a complete list, but it should serve to give you the flavor of what’s available.
Support
This is a curious case. If, by “support” we mean “doesn’t break anything” then the support here is broad. Using the HTML5 Shiv code snippet or the full blown Modernizr library every browser that matters supports the HTML5 elements. If you’re expecting user agents to do something interesting with your new elements, then the support level is much lower. Read the rest of this entry »
I’m going to be presenting my Intro to CSS talk at Design Camp Boston on November 6, 2010. It’s at NERD. If you can’t make my Boston PHP Meetup version of the presentation, here’s your chance. Failing that, make sure to say hi if you’re there, because I’ll be around all day taking in the goodness.
I haven’t posted about this yet. I’m an incredible idiot. I’m presenting at the Boston PHP group in October. My presentation is a couple of weeks before Steve Krug. No pressure.
Is CSS still a mystery to you? Do you find yourself editing your styles over and over justo get them to display correctly in IE and Firefox? Have you created a powerful application, and want it to look nice and clean? Do you want to take your knowledge of CSS and Design to the next level?
In this presentation Rob Larsen will step through the basics of Cascading Style Sheets (CSS,) the visual language of the Web. Starting with the most fundamental concepts and finishing with concrete examples illustrating common patterns, this presentation will serve as a launching point for those new to CSS and will strengthen the understanding of the core principles for developer or designer more experienced with CSS.
In this event you will learn:
Basics of CSS
Design & Layout
Web Standards
Rich Visual Behaviors
CSS1, CSS2, CSS3
Frameworks, Abstractions, etc.
Dealing with cross browser support
Separation of style, content and behavior
Testing
Tips & Tricks
If you still fumble with CSS and want to take your experience to the next level, then this event is for you.
About the presenter:
Rob Larsen has more than 11 years of experience building and designing web sites and web applications. Currently he’s a Consultant at Isobar, working for some of the world’s largest brands.
Prior to joining Isobar, Rob was the Principal Presentation Engineer at Cramer. At Cramer, Rob and his team produced standards-based, accessible and SEO-friendly sites and rich media applications. Before that, Rob worked for several years as a consultant for clients like Compete, Duracell, Gillette, Boston’s Museum of Science, PC Connection, RSA Security, State Street Corporation and Webex.
We relaunched the Cramer blog today. It’s a soft launch. We’re hoping to shake out any kinks over the quiet time around the holiday. I did the initial HTML5/CSS3 templates and then shepherded the project for a couple of weeks* until I was freed up enough this past week to get the thing out the door. Read the rest of this entry »
I’ve always preferred the “IE Box model.” I’ve always wanted width to actually be the width of the element. Instead, I’ve been forced, for years, to break out my math skills to calculate “actual” value of the width property by subtracting padding, margin and borders. That still seems broken to me after all these years.
As I’ve mentioned I’m doing a couple of HTML5 implementations and in one of them I was faced with some “post” boxes in a WordPress theme that featured both rounded corners and a drop shadow. Since I’m using already using Modernizr, which exposes specific CSS3/HTML5 feature support on the HTML element, I figured I’d do a little bit of extra work and use some CSS3 magic to make the design happen in modern browsers. For this post I’ll skip the extra work bit (a little JavaScript to insert extra markup in for Internet Explorer/Opera) and just look at the implementation for fancy new browsers (Firefox 3.5 and the latest/greatest Webkit based browsers.)
