If you were to use <strong> and <em> tags in HTML5 the same way that you’re accustomed to, it would be fine. As many have stated, HTML5 is backwards-compatible with old-style trends in SEO, accessibility, and markup, so your pages won’t break or be considered obsolete or deprecated.
The hype today is all about the new HTML5, the newest version of HTML that has combined classic HTML with XML, plus more features for modern web development. It is also, technically, the new version of XHTML 1.0, and in the near future it will be the main markup language we use for computer-based website creation (as opposed to mobile devices).
A long time ago, in a galaxy that feels a very long way away, multimedia on the Web was limited to tinkling MIDI tunes and animated GIFs. As bandwidth got faster and compression technologies improved, MP3 music supplanted MIDI and real video began to gain ground. All sorts of proprietary players battled it out—Real Player, Windows Media, and so on—until one emerged as the victor in 2005: Adobe Flash, largely because of the ubiquity of its plugin and the fact that it was the delivery mechanism of choice for YouTube.
The HTML5 <canvas> element has a unique history. Starting out as an Apple creation and dating back to 2004, canvas was eventually added to the official W3C HTML5 spec, becoming one of the most interesting and exciting parts of HTML5.
Unfortunately, this element takes a bit of work to understand and, unlike your usual run-of-the-mill HTML elements, requires more than just static markup and styling.
HTML5 introduces numerous new options to create more functional web forms. In this article, Jean-Baptiste Jung will show you exciting new HTML5 features to improve your forms and make them more functional and user-friendly.
The new canvas tag in HTML5 is known for its illustration power. It’s basically an empty element on which you can write and sketch using Javascript. But there’s a hidden power: image manipulation.
HTML5 has a new attribute, contenteditable, which can be applied to any element which allows it to be edited directly in the browser window. Think of text input with a predefined value, but it can literally be any element. Form elements like text inputs support the :focus pseudo class, which allow us to style those elements when they are clicked upon or otherwise navigated to.
There’s a lot of buzz going around about HTML5. Big companies such as Apple are predicting that it’s the technology that will sign the death warrant of the popular Flash platform that powers a lot of rich internet apps and complex dynamic web components.
For the most part, Flash has always been the standard for showing video
on the web (think of YouTube and Vimeo), supported in all browsers with
the only exception being the iPhone and most recently, the iPad.
But now, with HTML5, the new video tag is creeping into our
lives and opening up many new, exciting and standardized media
possibilities for web developers.
In this quick tip, we’ll review how to work with HTML 5 video in your own projects. Because older browsers and Internet Explorer do not understand the <video> element, we must also find a way to serve a Flash file to viewers who are utilizing those browsers.
