Posts under CSS3
This is a simple example of a mouse-over shine effect I created using purely CSS. It uses a CSS generated element and CSS3 transitions to animate the effect. See the comments in the markup below for further explanation of how it works.
Live demo:
Simple HTML markup:
And the CSS:
.myButton {
width: 110px;
height: 30px;
background-color:#0099cc;
text-align: center;
color: #FFF;
position: relative;
}
/* button hover style if required */
.myButton:hover {
}
/* generated element for shine effect.
* normal state is semi-transparent
* white but with zero width. Set no
* transition here for no mouse-leave
* animations. Otherwise the effect
* will play in reverse when your mouse
* leaves the element
*/
.myButton:after {
content: "";
position: absolute;
top: 0px;
left: 0px;
width: 0%;
height: 100%;
background-color: rgba(255,255,255,0.4);
-webkit-transition: none;
-moz-transition: none;
-ms-transition: none;
-o-transition: none;
transition: none;
}
/* on hover we animate the width to
* 100% and opacity to 0 so the element
* grows and fades out
*/
.myButton:hover:after {
width: 120%;
background-color: rgba(255,255,255,0);
-webkit-transition: all 0.3s ease-out;
-moz-transition: all 0.3s ease-out;
-ms-transition: all 0.3s ease-out;
-o-transition: all 0.3s ease-out;
transition: all 0.3s ease-out;
}

About 7 or 8 months ago I built a tile based launch page at work to launch learning modules which looked similar to the Windows 8 start screen. When I had spare time I kept building on and adding 3D animations to match it even closer to Windows 8. Then I kind of forgot about it until this week when I stumbled upon this article Creating Windows-8-like 3D animations with CSS3 and jQuery which provides a tutorial on creating a similar effect.
I had been meaning to do a post on my laucher when I first started making it but it never happened. So now that that article reminded me I thought I should post it. I am not going to provide any explanations of the code or tutorials but rather just show a demo (It’s HTML and javascript so you can just view the source anyway). I have ripped a bunch of LMS related code out of it and turned it into a web page launcher.
Click a tile to launch an ‘app’ (in this case a website). Hover you mouse over the top or bottom right corner for the ‘charms’ bar to close the site and return to the start screen. I have currently only tested it in Chrome and on an iPad and there isn’t a way to get to the charms bar on iPad yet.

Just another quick post tonight. I have bigger one lined up for tomorrow I promise. I just wanted to show a little experiment I did a while back with JavaScript – accessing the Accelerometer and Compass data in Safari on the iPad. Below is a short video demonstrating it if you don’t have access to an iPad. If you do have one – visit the link following the video. I might also mention that the arrow/circle image was all created using CSS3 too!
And here’s the link to the demo.
To get the source – just go to the above link and right click > view source.

Update: this post was made when I was using a different blog design. Please view the original swf file here.
Below is a little experiment I did which involved creating a version of this blog’s image flipping Flickr feed header (which I made in Flash) – in HTML/CSS/Javascript.
Luckily jQuery includes a JSON parsing feature and Flickr provides a JSON feed and so it was very easy to get the Flickr feed. The image flipping was done with CSS3′s 3D transforms and so unfortunately it will only work in Chrome and Safari. Now I just need to work out how to get more than 20 images from the Flickr feed (I need 36 to fill the header), and turn the images black and white. I found a jQuery plugin that apparently can apply image effects but I haven’t gotten it to work yet.
