Using jQuery for Background Image Animations After reading Dave Shea's article on CSS Sprites using jQuery to produce animation effects, I felt like playing around with things to see what could be done but accomplish it with a simpler HTML structure (no need for adding superfluous tags) and simpler code, too. Changing the position of the background image felt to be the best approach to creating the type of effect we're looking for (and I'm not the first to think so: see the examples at the end of this article). jQuery is a great library for this type of task but out of the box, it can't animate background position properly because of the need to animate two values instead of just one (too bad not all browsers implemented the non-standard background-position-x and -y like Internet Explorer). You'll have to use the Background-Position plugin that is linked in the demo (the original plugin is no longer available on the jQuery site). Previous versions didn't support negative or decimal values properly. The HTML The Basic CSS The Image
Les limites de la fouille sociale de données Lors de la conférence de sécurité informatique Black Hat qui se tenait récemment à Las Vegas, Alessandro Acquisti, professeur agrégé de technologie de l’information et de politique publique à l’Ecole de Heinz de l’université Carnegie Mellon, a montré comment une photographie d’une personne pouvait être utilisée pour retrouver sa date de naissance, son numéro de sécurité sociale et d’autres informations en utilisant la technologie de reconnaissance faciale pour faire correspondre l’image à celles que l’on trouve sur les sites sociaux type Facebook. Acquisti reconnaît les limites de confidentialité de son travail, mais avertie que le plus gros problème ne repose pas tant sur la violation de la vie privée que sur l’inexactitude des données extraites des techniques d’extraction. Pour Alessandro Acquisiti, explique Erica Naone de la Technology Review, le risque est bien de voir demain l’information en ligne préjuger de qui nous sommes et se tromper.

The Worst Thing to Put on Your Company Website | BNET Last Updated Oct 5, 2011 12:42 PM EDT Turns out Satan is a Web programmer. Who else would have invented the captcha code -- the often illegible hieroglyphics used to prove you're a human being and not a spammer or other malicious "bot"? Whether you're placing an online order or just completing a simple contact form, this Devil's work now appears on more and more sites. I recently went to the website of a tiny (like two-person) company and just wanted to send an email, and it shot a captcha code at me. I question how many small businesses are at such huge risk of robot attack that they really need these in the first place. The most offensive, unfriendly, infuriating captcha of all is the classic "wacky word" characters, often buried within a web of random lines and other such obfuscation: But it doesn't have to be this way. Here are my top four favorites. CLICK for #4 >> © 2011 CBS Interactive Inc..

HTML Source: HTML Tutorials jQuery MagicLine Navigation These "sliding" style navigation bars have been around a while, I just thought I'd take a crack at doing it myself as the opportunity came up recently. Turns out it's really pretty darn easy. I put two examples together for it. The Idea The idea is to have a highlight of some kind (a background or an underline) follow you around as you mouse over the different links in the navigation. This will happen with jQuery and it's animation abilities. Typical list here.... <div class="nav-wrap"><ul class="group" id="example-one"><li class="current_page_item"><a href="#">Home</a></li><li><a href="#">Buy Tickets</a></li><li><a href="#">Group Sales</a></li><li><a href="#">Reviews</a></li><li><a href="#">The Show</a></li><li><a href="#">Videos</a></li><li><a href="#">Photos</a></li><li><a href="#">Magic Shop</a></li></ul></div> Notice the .nav-wrap div around it. Do the ol' inline list elements with floated left anchors to get the list horizontal and avoid stairstepping. jQuery JavaScript Issues
How to Learn to Code for Free In days gone by, all you needed to make a website was a Geocities account and some basic knowledge of HTML. Maybe you’d throw in a bit of CSS (Cascading Style Sheets) if you wanted to get fancy. Times have changed, though, and now people build websites using at least one advanced coding language. Unfortunately there's no lingua franca when it comes to coding, so beginners can find it difficult to choose their first language. Choosing a Language The first step in learning to code is selecting a language to code in. Front-end coding relates to the appearance of your website. Back-end coding focuses on the work that happens behind the scenes. If you’re interested in back-end Web development, I suggest taking a crack at the Ruby programming language. For aspiring front-end coders, I suggest JavaScript. Where to Start With both JavaScript and Ruby, getting your first project working without a bit of experience with the language can be difficult.

Improve your photography with classical art. Adjusting your photographs to get the color 'just right' can be a chore. Think about this: The Old Masters of painting spent years of their lives learning about color. Why let all their effort go to waste on the walls of some museum when it could be used to give you a hand with color correction? When Photoshop entered the CS series it included a new tool called 'Match Color.' But there is another thing you can do with 'Match Color' that is much cooler: You can match the colors in your photos to those in famous paintings. I keep a directory of about 30 of my favorite paintings and anytime I need to do color correction, I just scan through them to find the one that gives the photo I'm working on the best look. This technique can be used in other ways. Stumble It!
Web Graphic Design Trends in 2012 Design trends for this year are bold and aim to grab audience attention. The focus is still on aesthetics but functionality is also crucial. Web style is the procedure of preparing and developing a website. Web developers use markup terminology, such as HTML for framework and CSS for demonstration as well as JavaScript to add communication to create websites that can be study by web surfers. The graphics should get through to the web users and grab their attention. 1. Bright hues of red, pink and green are being used on the web instead of neutrals. 2. Custom fonts can be put together using CSS Typeset, Typetester, WhatTheFont and other tools. 3. To grab user attention, large sized photos and backgrounds are used. 4. Keeping the animation subtle is important as it should take away attention from the main subject of the webpage. 5. The width of display has increased and pages should be made to fit different sizes of monitors. 6. These two technologies will be used enormously this year.
