<h3>Responsive Image Gallery with Thumbnail Carousel</h3>
A tutorial on how to create a responsive image
gallery with a thumbnail carousel using Elastislide.
Inspired by Twitter's "user gallery" and upon a
request to show an integration of Elastislide, we
want to implement a responsive gallery that adapts
to the view-port width. The gallery will have a view
switch that allows to view it with the thumbnail
carousel or without. We'll also add the possibility
to navigate with the keyboard.
</div>
</a>

<img src="images/thumbs/15.jpg"/>
<div>
<h3>Elastislide - A Responsive jQuery Carousel
Plugin</h3>
With the responsive awakening in web design it
becomes important to not only take care of the
visual part of a website but also of the
functionality. Elastislide is a responsive jQuery
carousel that will adapt its size and its behavior
in order to work on any screen size. Inserting the
carousels structure into a container with a fluid
width will also make the carousel fluid.
</div>
</a>

<div>
<h3>Slicebox - A fresh 3D image slider with graceful
fallback</h3>
With the CSS3 3D transformations we can create some
neat effects by transforming elements in
three-dimensional space. Slicebox makes use of the
3D transforms properties and allows different kind
of effects. The main idea is to create
three-dimensional image slices that will rotate and
reveal the next image as another side of the 3d
object. In case the browser does not support 3D
transformations, a simple slider will be used as
fallback.
</div>
</a>

<div>
<h3>Automatic Image Montage with jQuery</h3>
Arranging images in a montage like fashion can be a
challenging task when considering certain
constraints, like the window size when using
fullscreen, the right image number to fill all the
available space or also the size of the images in
use. With the following script you can automatically
create a montage, either for a liquid container or a
fixed size container (including fullscreen), with
the option to fill all the gaps.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/12.jpg"/>
<div>
<h3>Image Zoom Tour with jQuery</h3>
Today we want to share a little zoom tour script
with you. Showing a main image initially, we want to
be able to zoom into certain parts of the image by
clicking on tags, using another image for the closer
view. This next step can contain other tags that
again allow to show more images.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/11.jpg"/>
<div>
<h3>Circular Content Carousel with jQuery</h3>
Today we want to share a simple circular content
carousel with you. The idea is to have some content
boxes that we can slide infinitely (circular). When
clicking on the more link, the respective item moves
to the left and a content area will slide out. Now
we can navigate through the carousel where each step
will reveal the next or previous content box with
its expanded content.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/10.jpg"/>
<div>
<h3>Portfolio Image Navigation with jQuery</h3>
Today we want to create a portfolio image navigation
template with jQuery. The idea is to show some
portfolio items in a grouped fashion and navigate
through them in all 2D ways (horizontal/vertical).
Either the arrows or the little boxes below the
current image can be used in order to navigate.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/9.jpg"/>
<div>
<h3>Expanding Fullscreen Grid Portfolio</h3>
Today we want to share a neat experimental portfolio
template with you. The main idea is to have a grid
layout that we create with jQuery Masonry. Clicking
to view more, we expand the according item to
fullscreen in order to show a longer description of
the item and a representative fullscreen background
image.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/8.jpg"/>
<div>
<h3>Content Rotator with jQuery</h3>
Today we want to share a fancy content rotator with
you. It shows some image with a headline and
sub-headline in each slide and allows navigating
through the slides using the thumbnails that also
contain a headline. Hiding the thumbnails will
reveal a scrollable text container and the
navigation arrows will move up so that one can
navigate to the previous or next slides.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/7.jpg"/>
<div>
<h3>Vertical Sliding Accordion with jQuery</h3>
Today we want to share a slick and flexible vertical
jQuery accordion with you. The main idea is to
expand the accordion slices on click and show some
more information. The other slices will become less
opaque and squeezed. When navigating to the next
slice using one navigation arrows, a new slice will
slide in from the top or the bottom. Once a slice is
open and we navigate, the subsequent slice will open
on slide.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/6.jpg"/>
<div>
<h3>Animated Text and Icon Menu with jQuery</h3>
Today we want to show you how to create a slick menu
with a nice animation feature on hover. The idea is
to make some elements slide out, change and animate
the background color of the item and then slide the
elements back in with a different color.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/5.jpg"/>
<div>
<h3>Fullscreen Slideshow with HTML5 Audio and jQuery</h3>
In today's tutorial we'll create a fullscreen photo
slideshow to illustrate a New York picture series.
We will add sounds with the HTML5 audio element in
order to give life to the gallery and try to
recreate the ambient of this vibrant city.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/4.jpg"/>
<div>
<h3>Sliding Background Image Menu with jQuery</h3>
Today we want to share another jQuery menu with you.
This menu will have several panels, each one
corresponding to a different background image that
will show on all panels when we hover over a panel
label. Also, a submenu will slide out from the
bottom. This menu comes with some configuration
possibilities, such as the size of the image, the
hover effect and custom default states.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/3.jpg"/>
<div>
<h3>Grid Navigation Effects with jQuery</h3>
Today we want to share some neat grid navigation
effects using jQuery. In our examples we will show
you ten ways how to navigate through a set of
thumbnails. We'll take a look at some of the
possibilities and how to apply the effect.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/2.jpg"/>
<div>
<h3>Image Wall with jQuery</h3>
Today we want to show you how to create a neat image
wall with jQuery. The idea is to scatter some
thumbnails with different sizes on the page and make
a ribbon slide in when we click on the picture. The
ribbon will show some description next to the
picture and when clicking again on the thumbnail,
the ribbon will close and open again with a large
version of the image.
</div>
</a>
<a target="_blank" href="#">
<img src="images/thumbs/1.jpg"/>
<div>
<h3>Sliding Letters with jQuery</h3>
Today we have a neat little effect for you. We want
to bring some life to the standard hover effect by
playing around with the letters in an anchor word.
The aim is to slide in letter by letter when
hovering over a link element. We can either have the
same word or a different one and we can slide in the
new letters all the same time or one after the
other.
