I am trying to do something similar to expose from jQuery toolkit.
http://flowplayer.org/tools/demos/toolbox/expose/index.html
Except I am trying to use an image as a background and have the overlay over it and reveal only a portion of the image as 100% visible (kind of like a reverse highlight).
My current solution is:
I make an overlay on a image background div and make the z-index of the visible section div higher than that of the overlay. But since the background of the visible section div is transparent the div just shows the overlay. The way the plugins I have seen get around this is by setting the background of the visible section div to a color allowing that whole div to set above the overlay since I am using a pretty big image, I don't have the option to use a colored background on the div. I also don't want to show a cloned copy of the original image because these background images are huge.
I couldn't find any documentation of how to do this online. I'd appreciate any feedback I could get.
My suggestion would be to absolutize the element, set it to a relatively high z-index, then sit your faded layer below that, but still higher than any other content. It would give the appearance of the effect you want.

I am creating a lightbox style plugin that opens an image in fullscreen and adds text about it next to it. I need a zoom animation, that just zooms the small image up to fill the screen. Since the small image is in a column layout, i need to move it out of the current dom structure. However i am unable to do so while doing the zoom animation.
So my question is:
Is there any way to move an element in the dom, or just change its position to fixed and keep its position on screen? I have jQuery avaliable
If all you want to do is get it done, this plugin could do the job.

Otherwise, I'd put the image in a container of the same size so that you can change the image display property without having your layout get screwed up.
You don't need to move the element in your DOM. Just change the css.
Also this stackoverflow question could possibly help you.
I've came across wunderlist.com site and just fell in love with the zoom-like pop-up they have on the image just beneath the header "Learn more about Wunderlist".
I'd love to implement something like this on my site.
Can somebody tell me how this is done? I tried to reverse-engineer, but with no luck :)
I'm not hoping for the whole ready code, but maybe some guidelines on how to achieve this with CSS/jQuery.
Or maybe you know some jQuery plugin that I could use?
They are using all CSS. Pretty simple really.. I would code a full js fiddle example for you but I don't have the time, so instead I will list out the different elements you need and how they interact.
First the large image is just a div with a background image with set
dimensions.
The circular images themselves are generated from one large image containing all of the circles in one spot, this is called a sprite. The circles are just div's with background images and background positioning to position the correct circle inside the box from the sprite image.
The text boxes themselves are also div's with a standard H2 and P tags for the text.
Everything is absolute positioned in order to achieve the proper layout.
The small circles are div's with :hover states that are absolute positioned over their respective targeted areas.
The animation on :hover is achieved by the use of css3 transition and css3 transforms.
This should get you started.
Comment if you have questions.
Had some time to have some fun: http://khill.mhostiuckproductions.com/siteLSSBoilerPlate/fun-experiment-mh/
Try looking at two main aspects:
Open up your inspector tool of choice and look at what happens to body.login .feature
...more specifically, look at what happens to its transform: scale and opacity values upon :hover.
Hint: the transition is mainly on them.
Still in your inspector, change the scale to (1) and the opacity to 1. How it smoothly gets from one state to the other is dictated by the transition property.
This isn't meant to tell you exactly how to achieve it, but to get you on your way :)
It's not that hard actually. The Wunderlist team has even made it easier. They have a large sprite image with the zoomed images cropped and ready with rounded corners, borders and shadows. You can see it here: https://wunderlist2.s3.amazonaws.com/179510ff7c929bfcc6e9819f3c2539baca5d3325/images/welcome-screen.png
What you do is on mouseover you show a half transparent black background (can be position: fixed with full width and height). Then you create a element with the sprite as the background image (even better, have a class ready in your css and append it to your newly created element). Set position to the position of the hovered element.
When added to the dom animate the transform scale of the element (starting with something like scale(.24) as they do).
Well since you tried reverse engineering. I'll try and guide you along that path.
There is only one div with id overlay which is changes it's place & content, on hover of any div with class feature. Work your way further from their app js, it's not minified.
The content of the popup in this case is an image moved to different positions.
I have 4 images stacked on top of each other, see below:
I'm trying to achieve two things:
When the mouse is over an image that is in the background, that
image should come to the foreground with a fading effect. There is
also different text below each image, that text should come to the
foreground. (no fading needed there)
The result should be like this:
Every 10-15 seconds (without user input), the next image on the right should fade in
automatically.
Technically, I thought about putting each image and text into a separate div, and playing with the z-order. The fading effect could maybe be achieved using jquery, but I've not used that before, unfortunately.
Any example code, specific help or pointers is greatly appreciated.
Thanks!
Although it's impossible to control the fade of an element through his z-index
we can always trick what our eyes see.
DEMO GALLERY
To achieve that we can do:
Insert into our gallery a DIV element that will grab the src attribute of the current image and set it as his background image
hide the current image, position the DIV on this image .position()
fade our DIV in/out
reset image visibility
Let me know if you have some issues, I can comment my code to make clearer the steps I used.
Happy coding
Take a look at this plugin. Just explore it, this has got 100s of different effects which you might like to use in your case.
http://jquery.malsup.com/cycle/browser.html
Basically what I have is a page with a background image and when I have content which is quite long and overflows. I want the text to be inside that image and it appears to fade out when scrolling at the end of the image and the top of the image. I do not want internal scrollbars. The background image itself is fixed and centered and I want the text to always remain inside there.
Is this possible? if this is not clear then I will try and explain myself further.
I have looked at options in Jquery and CSS fading but cannot find exactly what i want.
Any help is appreciated!
Thanks

I would suggest you plant an image overlay (white to transparent) at the top and bottom of the div, but that might not work because of your background...could we perhaps see the background you are using?
The two images Nexxeus says should be placed in a fixed position at the top and bottom of the browser. You shouldn't touch what the overflow does, since it will be hidden below the two images.
The client wants to have a simple slideshow with a little twist: he wants the menu to be on top of the image being changed.
what would be the way to achieve this using css and javascript?
Don't use a background image, just put the menu in a division and position it absolutely on the top of the image somewhere. You can't resize background images and if the images are bigger than the client's visible area they will be cut off.
As you normally do. The order of the image and menu is important. If the menu is after the image then you are ok. If you can't/won't change the order then you'll have to use the css z-index property.
