This technique produces something similar to the wiggle you get on an iPhone when deleting items.

Be aware that keyframe animation is still very poor in Chrome and cases freezing and jumping if multiple items are animated at once.

The animation css below results in a hovered element rotating back and forth around it’s centre point. You can update the number of degrees and length of animation to change the appearance.

Just add this css and give your element the class ‘wiggler’ to implement

 
/* safari and chrome */
@-webkit-keyframes wiggle {
	0% {-webkit-transform:rotate(4deg);}
	50% {-webkit-transform:rotate(-4deg);}
	100% {-webkit-transform:rotate(4deg);}
}
 
/* firefox */
@-moz-keyframes wiggle {
	0% {-moz-transform:rotate(4deg);}
	50% {-moz-transform:rotate(-4deg);}
	100% {-moz-transform:rotate(4deg);}
}
 
/* anyone brave enough to implement the ideal method */
@keyframes wiggle {
	0% {transform:rotate(4deg);}
	50% {transform:rotate(-4deg);}
	100% {transform:rotate(4deg);}
}
 
.wiggler:hover {
	-webkit-animation: wiggle 0.5s infinite;
	-moz-animation: wiggle 0.5s infinite;
	animation: wiggle 0.5s infinite;
}

In case you weren’t aware, you can reorder the results you already have from a previous Yii call. For example…

 
$users = User::model()->findByPk(2);
$posts = $user->posts(array('order'=>' created Desc '));

There were just ordered our users posts by created date descending.

We can also do filtering…

 
$users = User::model()->findByPk(2);
$posts = $user->posts(array('condition'=>' status=1 '));

So now we only have active posts. We could also combine a condition and a status.

The example given on the Facebook developer documentation page ( http://developers.facebook.com/docs/reference/fbml/serverFbml/ ) doesn’t work. This one does.

Note how some html is escaped and the multi-friend-selector is inside the form.

The code below allows you to add the large version of a friend select in the form of an invite tool to your iframe facebook applications:

<fb:serverFbml style="width: 755px;">  
     <script type="text/fbml">
        <fb:fbml>
            <fb:request-form
                action=""
                method="post"
                invite="true"
                type="XFBML"
                content="This is a test invitation from XFBML test app
                &lt;fb:req-choice url=&quot;see fb:req-choice docs for details.&quot;
                    label=&quot;Ignore the Facebook test app!&quot; /&gt;
             ">
				<fb:multi-friend-selector
                    showborder="false"
                    actiontext="Invite your friends to use Socially." />
             </fb:request-form>
         </fb:fbml>
    </script>
</fb:serverFbml>

Twitter’s bootstrap css currently doesn’t support tabs on the right hand side or floated right. We’ll here is the css to allow it.

We’ll stick to existing naming. Twitter use secondary-nav within topbar so let’s use that…

.tabs .secondary-nav {
	float:right;
	margin-left:10px;
	margin-right:0;
}

The the html for the tab you want to float right you need:

<li class="secondary-nav"><a href="#">Link Text</a></li>

The outcome is most tabs on the left and any with the new class positioned over to the right.

If you own a Mac and you haven’t heard of Alfred App then you’ve likely been living in a bunker for a while.

At very least Alfred allows you to quickly start applications. If you choose to delve deeper you can use it to search and open files, run applescripts, quick jump to webpage searches, send emails, control iTunes and 999 other clever tricks.

When you first get your Mac you will likely have heard of Spotlight, a built in application that can be used to search applications and files. It’s hotkey is cmd-space. It isn’t as flexible as Alfred App but it has the best hotkey combination going.

Before we start if you’ve turned off Alfred’s menu bar icon, turn it back on in Alfred appearance preferences. It’s makes for the easiest method of opening during hotkey move.

Here is how to move Alfred App to use cmd-space and Spotlight to use ctrl-space:

System Preferences -> Keyboard -> Keyboard Shortcuts

1) In the left column click Spotlight.
2) In the right column click the current key combination for spotlight of ⌘Space (cmd-space) and input your replacement key combination. I recommend ^Space (ctrl-space) although some other applications occasionally reserve it (such as Things App). At this point if you can see it you could also switch the second hotkey combination over to ⌥^Space (alt-ctrl-space).
3) Don’t worry about remembering the old hotkeys. If you change your mind later as you can click Restore Defaults to undo your changes.

You can close system preferences now.

So we’ve moved Spotlight, but now we need to move Alfred to ⌘Space (cmd-space).

Click on Alfred’s top hat menu bar icon and select preferences. (you may need to restart Alfred at this point for it to recognise that you’ve moved Spotlight to a new hotkey.

Choose General and you should see a large box Alfred Hotkey box. Click it and press our new hotkey for Alfred App.
⌘Space (cmd-space)

And that’s it. You should now see Spotlight when you hit ^Space (ctrl-space) and Alfred when you click ⌘Space (cmd-space).
