In the past two years, increased browser support has transformed CSS3 from a fringe activity for Safari geeks to a viable option for enterprise level websites. While cross-browser support is often too weak for CSS3 to hold up a site’s main design, front-end developers commonly look to CSS3 solutions for progressive enhancement in their sites. For instance, a developer might add a drop-shadow in Firefox, Safari and Chrome using -moz-box-shadow and -webkit-box-shadow, and then be comfortable with this design enhancement falling off for IE users.
But wouldn’t it be great if IE users could see the better version of the page? Fortunately there are cross-browser hacks for the more common CSS3 attributes. These hacks not only allow CSS3 attributes to work in all browsers, but in turn allow designers and developers to use CSS3 in the central styling of their sites.
In this article we’ll walk through … Read more…

Remember the code from Contra on original Nintendo? Up, up, down, down, left, right, left, right, B, A, start; it’s also known as the Konami Code and the 30 Lives Code.
This famous sequence of buttons from the 80’s isn’t going anywhere: in more recent times it’s been in a Moldy Peaches song, and used as an easter egg in Google Reader and Facebook, to name a few.
But I’m sure tons of great things can still be done with the code from Contra, so I built it into a simple jQuery plugin that can be easily used on any site.
The jQuery Contra Plugin allows you to call a function of your choice whenever a user enters the Konami Code (up, up, down, down, left, right, left, right, b, a, enter).

In Javascript it often makes sense to attach a stylesheet rather than style a bunch of individual attributes. Appending a stylesheet to the DOM has a number of advantages:
-
Stylesheets can be easier to work with than Javascript—it’s just more natural to use CSS syntax for styling.
-
It’s nice to avoid the cross-browser headaches associated with Javascript styling. Compare CSS’s simple float: left to Javascript’s style.styleFloat = ‘left’ and style.cssFloat = ‘left’.
-
Appending a stylesheet is better for performance when styling 15 or more elements.
-
CSS allows you to leverage pseudo-classes and define styles with the simple a:hover selector instead of both onmouseover and onmouseout event listeners.
There are a couple ways to append a stylesheet. Although it’s usually best to attach an external stylesheet, there are times when you need to build a stylesheet on the fly with Javascript. Let’s walk through the code we’ll need to append … Read more…

TranslateThis is a new Javascript widget that provides 52 languages of translation by leveraging the Google Language API.
Installing TranslateThis couldn’t be easier—simply copy and paste the widget code anywhere on your website, you don’t have to upload any files or change any settings.
Besides being easy to use, TranslateThis also provides many attractive features for developers. First off, requests to the Language API run in Javascript, so the translation is pretty fast. Additionally, the script is lightweight, weighing in at just over 11kb with another 7kb of imagery. And since it doesn’t depend on any Javascript library, TranslateThis can be implemented on any website without additional overhead. Finally, TranslateThis has been tested in all modern browsers and its user interface is designed to be straightforward and seamless.

There were a lot of good speakers at today’s jQuery Summit, but Paul Irish’s talk on jQuery Anti-Patterns for Performance & Compression was my stand-out favorite. Covering a number of advanced jQuery performance optimization techniques, this speech put my knowledge of jQuery optimization to shame.
Before Paul’s talk my understanding of jQuery performance tuning was fairly simplistic:
- Optimize selectors to descend from an id if possible.
- Use tag names when selecting classes and don’t use an excessive number of selectors.
- Define variables instead of selecting the same object repeatedly.
- Optimize your code replacing repetition with object oriented functions.
But the information Paul presented blew all that out of the water. Here are 10 jQuery performance rules I gathered from his presentation:
1. Optimize selectors for Sizzle’s ‘right to left’ model
As of version 1.3, jQuery has been using the Sizzle Javascript Selector Library which works a bit differently from the … Read more…

For the past couple years jQuery has been gaining in popularity, from a hot script with easy CSS selectors released by John Resig in 2006, all the way to jQuery 1.3.2, probably the most widely used Javascript library today. The jQuery core has been constantly expanding, offering new methods and performance tuning with every release, in addition to the wide variety of jQuery plugins that are released almost daily.
Known for publishing resources for the latest development trends, Packt Publishing has recently released an updated version their jQuery book: Learning jQuery 1.3, by Jonathan Chaffer and Karl Swedberg of Learning jQuery (the website). This new resource provides an excellent introduction to jQuery as well as going into detail on some of its finer topics. I’d highly recommend it for anyone who is fairly new to jQuery—it will give you a great head start in … Read more…

My favorite thing about web development is the wide variety of skills it uses. Being a good developer means staying on your toes and always learning, because there are so many important skills and these are constantly changing.
Here’s a checklist of 10 skills that are some of the most important for good web developers to have. These focus a bit on front-end skills, but they apply to all developers:

I’m happy to announce the release of QuickFlip 2, a major reworking of the jQuery plugin that flips any piece of HTML markup over like a card. The new version is faster and even easier to use—simply call the flip animation through a jQuery selector and the QuickFlip will flip the front panel to show its back. The flip effect is similar to the UI animation on the iPhone
Download QuickFlip 2 for jQuery
Read the QuickFlip documentation
QuickFlip works by using an animation shortcut that is barely noticeable when flipped quickly (hence the name). This shortcut improves performance while allowing the flip effect to work smoothly with any piece of markup regardless of images, backgrounds or CSS.
It provides an attractive alternative to other slower and more resource heavy Flash and jQuery flip animations. However if you want a smoother option with … Read more…

YouTubin’ is a jQuery plugin that makes embedding YouTube videos clean, easy and unobtrusive. In its simplest form, YouTubin’ grabs any links that point to a YouTube page and replaces them with an embedded video. To do so, YouTubin’ leverages SwfObject 2 if available, but otherwise just embeds the video through standard markup.
Advanced options include flagging specific video elements using a jQuery selector and setting a variety of swf properties such as dimensions, flash version, flashvars and params. Youtubin’ can even be used to cause the video to embed once a link is clicked rather than when the page loads.
