HTML (Hyper- Text Markup Language) is the language that tells a web browser what to do with the text, images, and other media—the stuff—you want others to see. There are good ways to use these tools, and there are bad ways. Web brows- ers are smart application programs. They can take badly written HTML and still present a respectable-looking web page. However, there are still very good reasons for learning how to write good markup. This book is about creating web pages that . Are pleasing to look at and fun to play with . Are friendly to search engine robots . Are easy to update and maintain over time The Web can be understood through a number of metaphors that allow us to think of a website as a place within a realm we explore. We even socialize within its “spaces.” But that is just a useful illusion. Under the hood, the Web is not like that at all. Chapter 1 introduces the client/server technology that web authors and developers use to create the illusion. Even if you consider yourself an experienced web user, Chapter 1 is worth skimming. Chapter 2 is all about the elements of HTML, including some of the more interesting HTML5 additions. It has many examples illustrating how to mark up documents semantically so that the resulting web page provides all the right information to readers, both human and robot, and that it is easy to update. Our first obligation in design is to please ourselves. With good document structure, a website can be easily styled in a consistent manner across all pages. Chapter 3 explains, with many examples, how to use Cascading Style Sheet (CSS) statements to apply styling to document elements and create people-pleasing web pages. Chapter 4 is about using HTML as a contributor to other websites that accept marked-up content. Five examples are given: blogging, Google Docs, eBay selling, Wikipedia editing, and HTML email. xiv Despite the many options for putting content online, sometimes your orga- nization’s objectives or your personal goals dictate building and running your own website. Chapter 5 explores many of the issues involved, including website structure, organization and navigation, and search engine optimization. At the end of this book you’ll find quick-reference guides to HTML ele- ments and CSS properties, including the new elements and properties in the HTML5 and CSS3 draft specifications. There is no list of references to resources. The W3C’s website at w3.org and Wikipedia’s articles on HTML and CSS should cover anything from a technical perspective. You know how to search the Web for other guides, tutorials, and examples. Finally, this book is about you, because you are changing from a person who uses the Web for information and services to one who contributes to the Web. People are discovering that the joys of online shopping pale in compari- son to the pleasures of creative collaboration. There is a place on this new Web for your stuff, and this book is about how to create content with style. I hope you will find it useful. What’s Not Covered in This Book and Why Not This book is not intended to be a complete reference guide to HTML5. Such a book would be at least three times larger than this one and would be out of date shortly after publication.

  • Appendix a the Ten Commandments for Websites
    Appendix A The Ten Commandments for Websites Welcome to the appendixes! At this stage in your learning, you should have all the basic skills you require to build a high-quality website with insightful consideration given to aspects such as accessibility, search engine optimization, usability, and all the other concepts that web designers and developers think about on a daily basis. Hopefully with all the different elements covered in this book, you now have a solid understanding as to what goes into building a website (much more than code!). The main thing you should take from this book is that you don’t need to be an expert at everything but ensuring that you take the time to notice what’s out there and deciding what will best help your site are among the most important elements of the process. As you leave this book and go on to updating your website over time and perhaps learning new skills, always remember to be brave, take risks (through trial and error), and never feel that things are getting too hard. If you choose to learn skills that were only briefly mentioned in this book, like scripting, or to get involved in using content management systems and web software, go at a pace that you feel comfortable with. With that in mind, let’s go over the 10 most important messages I would personally recommend. After that, I’ll give you some useful resources like important websites for people learning to create for the Internet and handy software. Advice is something many professional designers and developers give out in spades after learning some harsh lessons from what their own bitter experiences.

Discuss its features ¾ JavaScript is a client-side scripting language and is the defacto scripting language for most web-based application. ¾ It is used to enhance the functionality and appearance of Web pages by making it more dynamic, interactive and creating web pages on the fly. ¾ JavaScript is interpreted by the browser. ¾ Statements are terminated by a ; but is not required. ¾ JavaScript standard is defined by ECMA to which Netscape is fully compliant whereas IE complies with a modified version known as JScript. ¾ The <script> element introduces a client-side scripting language. ¾ It is generally placed within the <head> element, but can also be part of <body> o The type attribute specifies the MIME scripting language and its value is text/javascript for JavaScript. <html> <head> ... <script type="text/javascript"> <!-- Put your JavaScript code here // --> </script> </head> <body></body> </html> ¾ The script is executed either when page is loaded or when given event occurs. ¾ The script will not be executed if it is disabled in the browser environment. ¾ For browsers that do not understand javascript, the entire script code is enclosed within xhtml comment. ¾ Script can also be placed in a separate file and pointed by src attribute. ¾ JavaScript is an object-oriented language and has a set of pre-defined objects (document, window, form, etc) to access and manipulate XHTML elements. ¾ An object's attribute is used to set/read data, whereas a method provides service. ¾ Javascripthas

  • In Action Second Edition
    Bear Bibeault Covers jQuery 1.4 and jQuery UI 1.8 Yehuda Katz IN ACTION SECOND EDITION MANNING Praise for the First Edition This is an excellent work, a worthy successor to others in Manning’s “In Action” series. It is highly readable and chock-full of working code. The Lab pages are a marvelous way to explore the library, which should become an important part of every web developer’s arsenal. Five stars all ‘round! —David Sills, JavaLobby, Dzone I highly recommend the book for learning the fundamentals of jQuery and then serving as a good reference book as you leverage the power of jQuery more and more in your daily development. —David Hayden, MVP C#, Codebetter.com The Elements of Style for JavaScript. —Joshua Heyer, Trane Inc. For those new to jQuery, this book is a good primer that covers a range of common uses of the framework.... The examples throughout the book are relevant, and make the point effectively. The code snippets are easily distinguishable from the rest of the text, and the text is clear and easy to follow. —Grant Palin, Blogger It works and makes for a very readable book that you can just breeze through very quickly and pick up and retain a lot of information. —Rich Strahl, Blogger Thanks to the authors Bear Bibeault and Yehuda Katz and their exemplary style, this compre- hensive book, or operating manual as it might be called, can be taken in a front-to-back approach to learn from scratch, or as a reference to those already dabbling in jQuery and needing verifica- tion of best practices.

  • Why Websites Can Change Without Warning
    Why Websites Can Change Without Warning WHY WOULD MY WEBSITE LOOK DIFFERENT WITHOUT NOTICE? HISTORY: Your website is a series of files & databases. Websites used to be “static” because ​ there were only a few ways to view them. Now we have a complex system, and telling your webmaster what device, operating system and browser is crucial, here’s why: TERMINOLOGY: You have a desktop or mobile “device”. Desktop computers and mobile ​ ​ ​ devices have “operating systems” which are software. To see your website, you’ll pull up a ​ ​ ​ ​ “browser” which is also software, to surf the Internet. Your website is a series of files that ​ ​ needs to be 100% compatible with all devices, operating systems and browsers. Your website is built on WordPress and gets a weekly check up (sometimes more often) to ​ ​ ​ see if any changes have occured. Your site could also be attacked with bad files, links, spam, comments and other annoying internet pests! Or other components will suddenly need updating which is nothing out of the ordinary. WHAT DOES IT LOOK LIKE IF SOMETHING HAS CHANGED? Any update to the following can make your website look differently: There are 85 operating ​ systems (OS) that can update (without warning). And any of the most popular roughly 7 ​ ​ ​ browsers also update regularly which can affect your site visually and other ways. (Lists below) ​ Now, with an OS or browser update, your site’s 18 website components likely will need ​ ​ updating too. Once website updates are implemented, there are currently about 21 mobile ​ devices, and 141 desktop devices that need to be viewed for compatibility.

This project examines two distinct solutions, lawsuits (a consumer-driven solution) and AcceSS 2.1 transcoder (a technology-driven solution) to provide more information on two under- researched methods that could have far-reaching impacts on Web accessibility for the blind. First, an evaluation of the intraclass correlation (ICC) between homepage Web Accessibility Barrier (WAB) scores and WAB scores of levels 1-3 found that the homepage is not sufficient to detect the accessibility of the website.
