I’m happy to announce that jQuery Infinite Carousel 1.0.1 has been released. This new version, which can be downloaded from the jQuery Infinite Carousel page, fixes a few bugs, adds a new feature, and comes in a reorganized zip file with a demo.

Changes:

  • Bug fixed for caption box height for large values
  • Default format for captions is now HTML instead of text
  • Images now in their own folder
  • Demo added
  • Documentation updated

Over the years I’ve needed a quick reference for CSS shorthand properties for things like font, border, and background. While there are a few decent cheat sheets out there for this, inevitably I end up having to pull them off my wall and read them because they aren’t clear enough. I finally decided to make my own and I’m making it available to anyone who wants it. It’s a one page PDF which should fit nicely in a wall or binder. It covers the three properties I mentioned above since I find myself using them the most. While it’s true that there are more CSS properties that can be written in shorthand, I find that they’re either a) easy to remember (e.g. color:  #123 versus color: #112233) or they’re infrequently used (e.g. outline?). If you notice any errors please feel free to let me know and I’ll update the sheet.

CSS Shorthand Cheat Sheet

First of all, apologizes for the unplanned disappearance of this site (and a few others I run). Apparently a post or two received a lot of attention from reddit.com which caused our host to pitch a fit and shut our sites down. Lovely people. Knee-jerk reactions like this are always fun to fix. From what I’ve heard a lot of hosts have this type of shoot first ask questions later policy.

So what happened? On Thursday our site caused the server we’re on to get hammered and this must have set off some sort of alarms at our hosting provider. Now rather than look into the problem and do some basic troubleshooting, we were summarily moved from our old server to the stabilization server. However as our host now admits, they botched that up and didn’t move our databases over which caused the site to become dead. So for the past two days I’ve been going back and forth with them via email, their ticket system, and yes by phone. All that needed to be done was add a caching plugin to our site that got hammered and we should’ve been golden. However to do this, I needed web access to my site and functional databases, neither of which my host could seemingly provide.

For the time being we seem to be functional and hopefully we’ll be around for the foreseeable future. Thanks for your patience; mine are long gone.

About a month ago I was reading the New York Times online and they had an article which showed a road in Brooklyn that had been reconstructed to make it safer and more pleasing to the eye. To show the difference  in the reconstruction project, they showed a before and after picture using Flash that let the visitor drag a slider over the images, which were sandwiched with one on top of the other, so that you could easily see how dramatic the changes were. I immediately thought that this could be done in JavaScript using jQuery, so I set out to do it. Here’s the result:

Pretty slick no? The possibilities for this plugin are endless. Doctors can have before and after images of patients, Photoshop users can show the before and after differences between images, remodelers can show the before and after images of projects and on and on. This plugin weighs in at only 7K and can be used multiple times on a page.

Download

Download jquery.beforeafter.zip (version 1.1.0  – January 12, 2010)

What’s So Great About this Plugin?

  • Slick effect, no Flash needed
  • It’s just 7K (4K compressed)
  • Reusable on multiple containers
  • Degradable. If the visitor doesn’t have JavaScript they will still see both images.

How to Use

First, your before and after images must be the same size.  Each image must be inside its own div, and both of those within a containing div which must have an ID.  See this example.

<div id="container">
 <div><img alt="before" src="before.jpg" width="600" height="366" /></div>
 <div><img alt="after" src="after.jpg" width="600" height="366" /></div>
</div>

All images *MUST* have the width and height declared otherwise the plugin won’t work in Safari, Chrome, and any other webkit-based browsers.

To use the plugin you’ll need to have a copy of  jQuery and the jQuery UI, or point to jquery on Google and jqueryui on Google, and the plugin. Place the files on your site and link to them:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="jquery.beforeafter.js"></script>
<script type="text/javascript">
$(function(){
	$('#container').beforeAfter();
});
</script>

That’s it! You can apply the before/after plugin to any number of elements on a page.

Options

The following options are configurable:

  • animateIntro  – whether or not to have the drag bar start completely to the right of the container and gradually move by itself to the midpoint (default  false)
  • introDelay – if animateIntro is true, the number of milliseconds to wait before beginning the automatic drag bar move to the center of the image (default  1000)
  • introDuration – if animateIntro is true, the number of milliseconds it will take for the drag bar to go from the right side of the image to the middle of the image (default 1000)
  • showFullLinks – whether or not to display links below the image that a visitor can click on that will automatically show the full before or full after image (default true)
  • imagePath – the path (absolute or relative) to where you store the navigation images (default ‘/js/beforeAfter/’)

Options are added when calling the script:

$('#container').beforeAfter({
	animateIntro : true,
        introDelay : 2000,
        introDuration : 500,
        showFullLinks : false
});

Enjoy!

Demos

Note that the plugin uses several images which are kept in the same folder as the plugin. If you store the plugin in another folder on your server, update the path to these images.

jQuery Infinite Carousel Plugin

Update: The latest version of this plugin can be found here.

The other day, yet again, I went looking for a jQuery plugin that moved a set of images inside a display area. I’m not sure if this is a carousel, a gallery, a slideshow, or what. They all seem to share many common characteristics, but regardless I wasn’t able to find what I wanted, although I did find several different plugins that did part of what I wanted to do, which was to generate a simple unordered list of images and optionally have a caption for each one. If a visitor doesn’t have JavaScript enabled (yes both of them) they should still be able to see the images, but for the 99.9% of the web population that does have JavaScript enabled, they should get a simple, slick carousel of images.

So I set out to create my own plugin and here’s what I ended up with:

You can  move between images using the left and right arrows which when clicked, pauses the carousel. To restart the autopilot feature, just click the play button in the upper right hand corner. You can also obviously pause the show at any time by clicking the pause button in the same spot. Captions are optional. When the carousel is paused, you can minimize or close the caption window. The amount of time each image is displayed, as well as the length of time the transition between images takes are configurable. There’s a also an unobtrusive bar at the bottom of each image (which you can turn off) that shows how much time is left before an image changes.

Download

Download jquery.infinitecarousel.zip. (version 1.0.1 – 7/31/2009)

What’s So Great About this Plugin?

  • Unlike most carousel plugins which stop when the get to the last image,
    this one allows the show to go on infinitely without any user intervention.
    If you have three images you want to display, after the third image has been
    displayed, the first image will be next. Through some clever JavaScript, images are shuffled around so that it appears as if the carousel is a true carousel and never ends.
  • Captions are optional
  • It’s just 9K
  • Reusable on multiple containers
  • You can use CSS to add padding to the carousel area so that the previous and next images are hinted at (see demos below).

How to Use

First, all of the images that you want to display should be the same size and wrapped in a containing element (I recommend a div) which must have an ID.  Note that by using CSS, you can style the container (carousel) div to have left and right padding so that you can display a small amount of the previous and next images. The carousel must be a list where each list item is the image and optionally a paragraph containing the caption. See this example.

<div id="carousel">
<ul>
	<li><img alt="" src="p1.jpg" width="500" height="213" /><p>This carousel has no padding applied to it so you won't see hints for the previous and next images. Also, the progress bar could be disabled by setting just one option on the plugin.</p></li>
	<li><img alt="" src="p2.jpg" width="500" height="213" /><p>This is the caption for the second image. The height of the caption box is an option.</p></li>
	<li><img alt="" src="p3.jpg" width="500" height="213" /></li>
	<li><img alt="" src="p4.jpg" width="500" height="213" /><p>It's not easy being green.</p></li>
	<li><img alt="" src="p5.jpg" width="500" height="213" /></li>
	<li><img alt="" src="p6.jpg" width="500" height="213" /><p>You can easily mix images types. Gif, png, and jpeg all work without any issues.</p></li>

</ul>
</div>

All images *MUST* have the width and height declared otherwise the plugin won’t work in Safari, Chrome, and any other webkit-based browsers. Also, all images should be the same size.  If you want to have a caption with an image, it *MUST* exist in a paragraph after the image.

To use the plugin you’ll need to have a copy of  jQuery, or point to jquery on Google, and the plugin. Place the files on your site and link to them:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="jquery.infinitecarousel.js"></script>
<script type="text/javascript">
$(function(){
	$('#carousel').infiniteCarousel();
});
</script>

Finally, make sure that your CSS contains a rule for the width of the list within your container so that it’s set to a minimum of the combined widths of all your images. For example. #carousel ul {width:3000px}. At a minimum, the following CSS should be included in any page where the carousel exists (remember to change the width):

#carousel ul {
	list-style: none;
	width:1600px;
	margin: 0;
	padding: 0;
	position:relative;
}
#carousel li {
	display:inline;
	float:left;
}

Check out the demos including the CSS for examples.

That’s it! You can apply the infinite carousel to any number of elements on a page.

Options

The following options are configurable:

  • transitionSpeed – the time (in milliseconds) it will take to transition between two images (default 1500)
  • displayTime – the time (in milliseconds) to display each image (default: 6000)
  • textholderHeight – the height of the caption. This is a fraction of the height of the images. (default: .2)
  • displayProgressBar – Boolean. Whether or not to display the progress bar (default: 1)

Options are added when calling the script:

$('#carousel').panelGallery({
	transitionSpeed : 2000,
	displayTime : 10000,
	textholderHeight : .25,
	displayProgressBar : 0
});

Enjoy!

Demos

Note that the plugin uses several images which are kept in an images folder in the zip file (/js/infiniteCarousel/images/ by default). If you store the plugin in another folder on your server, update the path to these images.
