HTML 5 <ruby> Tag The HTML <ruby> tag is used for specifying Ruby annotations, which is used in East Asian typography. Ruby (also spelt rubi) characters are small, annotative glosses that can be placed above or to the right of a Chinese character when writing logographic languages such as Chinese or Japanese to show the pronunciation. Ruby annotations, are usually used as a pronunciation guide for relatively obscure characters. The <ruby> tag was introduced in HTML 5. Example This example demonstrates how to write the <ruby> element into your HTML code. Note: At the time of writing, the <ruby> element has limited browser support. Attributes HTML tags can contain one or more attributes. There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes. The attributes that you can add to this tag are listed below. Element-Specific Attributes The following table shows the attributes that are specific to this tag/element. Global Attributes

Planet HTML5 I’ve been asked again and again over the years what the absolute basics of web accessibility are. And while I always thought that it is not so difficult to find resources about these basics, the recurrence of that question prompted me to finally write my own take on this topic. So here it is, my list of absolute web accessibility basics every web developer should know about. Alternative text for images One of the questions I get asked the most is “which graphics require alternative text”? The answer to this question has three parts: All img tags require an alt attribute. All the above also applies to SVG graphics. Using proper alternative text does not just help blind and low vision screen reader users. Labeling form fields Another very common question I get, and a very common error I see on many many web pages even in 2015, concerns the labeling of forms and form fields. If you need something a little more fancy-looking, please do not fall back to using clickable span and div elements.

Introduction to RDFa II In part I of this series, we looked at how semantic features normally confined to the head of an HTML document can be used to add semantic richness to the elements of the body. Along the way, we defined six rules of RDFa: The link and a elements imply that there is a relationship between the current document and some other document; the @rel attribute allows us to provide a value that will better describe that relationship.The @rel and @href attributes are no longer confined to the a and link elements, but can also be used on img to indicate a relationship between the image and some other item.In ordinary HTML, properties are set in the head of the document, using @content with meta. In part II, we’ll learn how to add properties to an image, and how to add metadata to any item—and we’ll add a few more rules to that list. Adding properties to an image#section1 For example, to indicate when an image was created, we might do this: (Line wraps marked » —Ed.) Rule 7:#section2 Rule 8:#section4

Cyberduck | Libre FTP, SFTP, WebDAV, S3 & OpenStack Swift browser for Mac and Windows WebRTC 22 Excellent HTML5 Tutorials | blogfreakz.com HTML5 is giving web designers and developers new capabilities in the world of web development. With the presence of HTML5, web application development will be more fun. HTML5 introduces a number of new elements and attributes that reflect typical usage on modern websites. Some of them are semantic replacements for common uses of generic block (<div>) and inline (<span>) elements, for example <nav> (website navigation block) and <footer> (usually referring to bottom of web page or to last lines of html code). HTML 5 features like Canvas, local storage, and Web Workers let us do more in the browser than ever before. Even though HTML5 is not fully supported in major browsers, there are those that are pushing forward and experimenting with its new features. HTML5 Basics & Tutorials 1. 2.

Taste the Font Touch The Future: Create An Elegant Website With HTML 5 And CSS3 I’m sure that who chooses to work as web designer makes a choice of heart, a choice of love. He/she decides to bet any given day on his creativity and his ability of producing an idea and of making it tangible, visible and perceptible for all. These crazy men have my respect. But, also when the creative side is very important for a work, there exists a logical (and technical) part in all creative process. There are some moments and situations in which the creative mind needs an analytical method to achieve the objective, that is, for us, the creation of a well-done website. In his article on Design Informer titled “Web Design Iterations And Algorithm,” Adit Gupta explains how we can approach a web design work and how a website project can be processed in a number of iterations following a main algorithm. Five macro-steps to build an effective website using brain, pencil, paper, Photoshop, HTML and CSS. How HTML 5 And CSS3 Can Change Web Design Quick Overview On HTML 5 Sketch Your Ideas <!

W3C recognizes the importance of a clear signal to the community about the future of HTML. While we recognize the value of the XHTML 2 Working Group's contributions over the years, after discussion with the participants, W3C management has decided to allow the Working Group's charter to expire at the end of 2009 and not to renew it. What will happen to the HTML Working Group? The HTML Working Group will continue with its current charter. What are W3C's plans for XHTML?

JavaScript Madness: Keyboard Events Javascript Madness Intro Jan Wolter 1. Introduction This document summarizes the results of some browser tests done while attempting to implement key stroke handling code in JavaScript. The tests were originally done with the intention of learning just enough to write the code I needed to write. This data is based on tests of many, many browsers over many, many years, but is not comprehensive. The script used to collect the test results reported here is available at This document will usually refer to "Gecko" instead of "Firefox" and to "WebKit" instead of "Safari" or "Chrome". Previous versions of this document included coverage of the iCab 3 browser, but iCab has switched to using the WebKit rendering engine, and so presumably behaves exactly like Safari. 2. In all recent browsers, pressing a key triggers a series of Javascript events which can be captured and handled. 2.1. "Modifier keys" are one class of special keys. 2.2. 2.3. 2.4. 3. 3.1. 3.2.
