I'm attempting to make a webpage using fullpage.js, and have a very large background image. What I'd like to do is make it so that each time the user scrolls down, it also scrolls the background image down. Essentially, if the background image on section one starts at 0,0 and the screen is 750px tall, I'd like to make section two start at 0,750 on the background image.
Is there a way to do this that doesn't involve manually splitting the background image into a bunch of different images and assigning image one (from 0,0) to section one and image two (from 0,750) to section two, etc?
You can use the callbacks fullpage.js provides such as afterLoad or onLeave or even the class added to the body element with the form of "fp-viewing-1-2`.
Check out this video tutorial I created with a similar topic. Just apply the same principle.

I've got a client who has a library of images they want to use on a site as fullscreen backgrounds.
I'm using the slideshow functionality + api calls in Supersized js to act as the backgrounds for my slides/sub pages in a site navigation, this is playing nicely with my foreground elements to create a good multiple page effect.
The only issue is that some of their images don't work well centered, and should instead be top aligned (as the focal points of the images get cut off at larger window sizes if they're centered).
At the moment I'm doing a really nasty manual destroy and rebuild to make the adjustment when it's different (currently the images are managed in a CMS so the user just selects a box if the image is be vert aligned). This does the trick, but is clunky and has some nasty jumpiness.
Do you know of a way to do this without destroying/rebuilding OR is there a different plugin that could handle this (and still work with the pagination functionality I've described?)
Thanks guys!
You can try the jQuery.mb.bandGallery plugin. It has the advantage that, in fullscreen, it will resize and center the image to fit the screen.
Or you can try/get inspiration from some of the multiple articles and demos at tympanus.net/codrops, like:
Animated Content Menu
Fullscreen Image Blur
Responsive 3D Panel Layout
I have a bit of a dilemma in the sense that I can't seem to get a jquery image cycler working with scaling images.
What I basically have is a website with a small navigation list at the top, and then full screen images which can be cycled using a control at the bottom of the page. Previously I've used backstretch to get the desired effect for a background image that stretches with the browser window.
I was also hoping on using Jquery Cycle as the plugin to do the image slider (as I've used this countless times before).
The problem is that I need the effect of backstretch (ie. scaling images) but with a slider. I have tried using other plugins for the stretching but most of them only seem to allow the images to be scaled down (if the window shrinks) rather than upwards. I can't use backstretch because it takes up the entire body tag. I only need a container div to contain the stretched images (so I can have the header/navigation sitting at the top without cropping the images).
However I have no idea how to then get this to work with Jquery Cycle.
Has anyone done this before or have any examples of this working?
Thanks
May be late but take a look at http://jongaulin.com/2011/11/17/fullscreen-image-and-content-slider/. I hope this works for you.
I am trying to create a banner for the top of page, but haven't found any code yet that combines all of what I need. I have included an illustration of what I'm trying to do.
A) I have 4 buttons (each an image file), two to either side default image in the center. This is the main/inactive state.
All of the buttons would have similar animation when hovered over. For the sake of this question, I only illustrated two of the buttons.
B) If you hover over Box 1 (top left), the button would change and text and lines would slide out from left to right. Also, the center image would change. And, to make things extra challenging, the left button and center image would link to Page 1. When you move away, the text slides back to the left, and the image returns to the default state in A. The blue box would behave the same way, linking to Page 2.
C) In a similar manner, if you hover over Box 4 (bottom right), the button would change and text and lines would slide out from right to left. Also, the center image would change. The right button and center image would link to Page 4. When you move away, the text slides back to the right, and the image returns to the default state in A. The green box would behave in the same manner, linking to Page 3.
The closest I've found is this: jQuery image slide on hover effect (horizontal) I was thinking that if I used the static images of all (A) as a background image, maybe I could create a transparent sprite, with only the active version of the hovered button and the center image, to slide left or right on hover.
I can see how the above example might would work for Boxes 1 and 3 (top left and right) and give the illusion of the lines sliding out as the image slides either left or right, but I'm not sure how it would work for Boxes 2 and 4.
Am I on the right track, or am I asking for way more than what's possible in JQuery? I'd be fine with loosing the animated text (I could just make them part of the hover images), but the buttons and center image need to change on hover, and they need to link to a page.
I've made a widget in jQuery that was confused with flash before. I think you need to breakdown each element of your widget into discrete pieces. You are making a new widget. There will be no methods doing what you want. You will have to use the .animate() method explained here. http://api.jquery.com/animate/ You will be animating one CSS class to another CSS class using the .animate() method.
This page has a good primer on the animate method.
http://viralpatel.net/blogs/2010/03/understanding-jquery-animate-function.html
Here's what I would do:
I would make the HTML of the page you want.
I would create CSS of each style of box that you will have.
I would have all the same CSS directives on every box that will
animate. I have found the animate method more agreeable if all CSS
that is to be computed has the same parameters but with different
values.
I would use full resolution images in the 4 outer boxes.
I would animate the div containing the image, not the image itself.
I would make the image fill the div dynamically so that when I
changed the size of the div the image would be a gimmie.
I would work in firebug testing out different commands and see how
they behave. This is critical. The interactive javascript console
is your friend.
This is a big task... when you're done this will be a nice feather in your cap! Maybe after that you could turn it into a jQuery plugin for others to use!
I decided to mess around with this for a bit, here is what I whipped up so far. No links as yet, but for a half hour I don't feel too bad about that :)

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.
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.
