This is a great tool when writing out regular expressions. It helps me as I learn more and more about them.

For those of you that are just getting into JavaScript, this is a must-have tool for checking your code. It will tell you what you are doing wrong (using multiple var statements, spaces in wrong places, etc) in your code and will help you write better JS.
Flippy-Flip Navigation
With the adoption of Webkit browsers (Chrome, Safari and just about every mobile browser), It’s getting easier to use Webkit-specific CSS3. This idea came when I was looking at Chris Coyier’s CSS Tricks site. He was using some 3D css3 on some of his sponsors links. I thought this would be a good implementation on a navigation.
The html is a straightforward linked unordered list:
For the CSS, we are using:
#nav { list-style: none; padding: 0; } #nav li { display: block; float: left; } #nav li:hover a, #nav li:focus a, #nav li.current_page_item a { -webkit-transform: rotateY(360deg); background: #fffd8c; color: #005488; } #nav li a { display: block; padding: 11px 10px 9px; margin-right: 2px; color: #ff7a7a; text-decoration: none; text-transform: lowercase; /* css3 */-moz-border-radius: 8px; -webkit-border-radius: 8px; border-radius: 8px; /* css3 */-webkit-perspective: 700;-webkit-transform-style: preserve-3d; -webkit-backface-visibility: hidden; -webkit-transition: all .4s ease-in-out; -moz-transition: all .4s ease-in-out; -o-transition: all .4s ease-in-out; }
This could will work for the most part, but there is some instances that I’ve only been able to replicate on a Mac machine. When you hover over the link and stop before the animation is complete, the browser doesn’t know that you are hovered over the anchor. There is a quick jQuery fix for this:
$('#nav li') //Indicate to user that the
- is now clickable
.css(‘cursor’,’pointer’)
//Trigger click on anchor when clicking - .click(function () {
$(this).find(‘> a’).trigger(‘click’);
Now your navigation will have a sweet new CSS3 transition to it.
Two CSS properties that will now be available in iOS5 in September: overflow: scroll and position: fixed:
This a very good deck of what you can do to make your jQuery faster. Every little bit helps, right?
