There are many of us looking for a Javascript/CSS3 solution that can provide a windows7-like UI within a webpage, without using flash.
We need an Opacity mask, rounded borders, and a Blur...
We've got the Opacity and the rounded borders, now we need to be able to apply some Blur effects to a semi-transparent Div.
I tried the BlurFast effect from the Pixastic Library, but it only blurs the actual image, not the background we are seeing trough the image...
Basically, we want a Div to act as a Blur Mask over other contents...
If someone actually succeeded with this, i'll be glad to know its possible :) Thank you

very good article on blur showing the state of the art
sadly "masking" parts of your page, that blur everything behind, is not that easy.
maybe the suggestions in ths blog help you out, as they are very straight forward and from a totally different direction..
therefor to embedd html within svg and use svg-filters on html elements later on
Thought this could be relevant: Aero
Personally, I think the fact that the author states this to be "In other words, one of the most messy and most ineffecient implementations ever"... AND that he can onlt get the effect to work in a single browser... to be extremely telling.
There is no way to do this efficiently or cross-browser at the moment.
The only way you might be able to do it is by using Pixastic to create the blurred image within Canvas, export as dataURI, then use that image as the background for your div. If the div moves, then the positioning of the background-image should move accordingly.

I am making an iOS 7 style app in HTML/CSS/JS. We are using a lot of tricky techniques and want to be able to animate elements, so I'm applying them all in HTML/CSS/JS rather than just using the raw image.
For blurs, I am using blur.js with really nice results -- you can blur only behind a <div> and then you can animate the div around it and looks really nice because the image only behind the div gets blurred.
Unfortunately, we are also applying a saturation filter in Photoshop, and I'm trying to replicate that. It looks like everything on the web indicates you have to apply the desaturation to the image directly (via something like -webkit-filter:
saturate(50%);). If I do this to the image directly, I can't animate the div behind it without the image behind it looking goofy.
Any way to apply a desaturation "layer"? One brute force way I was considering was using the location of the div to determine where on the image to saturate, but worried this will destroy performance.
I'm trying to create several buttons that have 4-5 frames of animation in them, and rather than using the typical CSS method (where 1 image has both states, and CSS toggles between top and bottom), I was curious if anyone had an idea on how to do this with 4-5 frames rather than 2. Obviously CSS alone can't make this happen - but its becoming a real challenge to find ANY info on this. Because the images have individual animation, I can't simply use the opacity to fade into the new image, it has to contain all 4-5. Any help would be much appreciated!

have a look at k10k and see how the buttons in the top are done: animated png's and animated gifs ;)
The only way I can think of to do this without JavaScript would be for the hover state to load an animated GIF for the background image. Otherwise, you'd have to use something like jQuery to animate the background-position property instead.
for this you'll need to use an animated GIF. if you don;'t have a animated GIF creation tool installed, either use Photoshop, which may be massive overkill, or one fo the free tools like GIFted motion
A very non-traditional frowned upon way this can be done is to...
-Animate them as a flash object. Export the xml/flash and imbed it into the htm
I'm looking to use an animated cursor in JS. CSS custom cursors do not animate in most browsers.
I have heard of people (can't recall who) doing this. They hide the regular cursor (by setting a transparent custom cursor), then create an image that follows the cursor in JS.
Anyone have any better ideas to achieve animated cursors? Is there a jquery plugin that will do this for you? I recall reading a blog that talks about this. Anyone heard of people doing this before?
Thanks.
Have you tried using .ani cursors? Also see controlling cursors with css. I guess you could try to hack this together yourself, but I don't see how you're going to hide the original cursor. Do you really need anything other than the widely supported usualy functionality?
li { cursor: text; }
a {cursor: pointer;}
You can use a transparent cursor, but some in some browsers it will show a black square instead of being transparent. Also, I have seen a couple examples that use canvas to add effects to the cursor.
A possible example http://jsfiddle.net/5mN9p/ borrowed from this question Animated image mask following mouse in HTML
All I added was
body{cursor:none;}
or possibly
canvas{cursor:none;}
Which means you can draw anything you want on the canvas at the mouse's coordinates.
Not tried this, but you should be able to create a custom CSS rule (create a class, like .customcursor, set the cursor to url(/path/to/image.png) and then, on a setInterval() cycle between images. Then apply that to your document body.
I haven't a clue how often you can run this, but it should work.
Flip is a great JQuery plugin for flipping blocks, but it doesn't preserve the background while it animates the flip.
For example, I have this pretty background here, before I flip. While flipping, it gets ugly.
Is there a way I can flip this div nicely, keeping the pretty background I have, and maybe even achieve a smoother animation than I can get with Flip?
If I need to dive into this headfirst and code my own function for flipping a div, that's also doable, and I'd really appreciate some pointer there, if that's what I must do.
Thanks so much!
Try the jQuery QuickFlip pulgin, this one seems pretty neat with handling the background.
Try looking into momoflow, its a coverflow type of application that animates the background to different angles.
It's using the canvas tag however, which could be an issue for you if you want IE compatibility. However the technique the dev is using is to chop the the image into several vertical slices and animate their position. You could extend this functionality to introduce a full flip!
A really cool way to do this is use CSS 3 transformations. It's much better than using a script; you should always avoid using scripts where simpler methods can be employed.
I want take a section of a picture, for example the middle of a picure, and repeat only that section in the background of a div. Is this even remotely possible? I suppose I could do this in javascript, but that would be messy.
In theory the answer to my question should be able to take a single pixel from a picture and repeat it in a line, or as a solid background.
Does anyone have any idea how I could do this in CSS?
You might be able to achieve this effect using the CSS3 border-image property.
Unfortunately, I am not aware of a way to do this sort of thing in CSS2. Also, I don't think that you can do this via CSS sprites, because sprites don't stretch parts of your image—they just allow you to show certain parts of the image.

Contrary to what some here have stated, depending on the image, you CAN do this with CSS/Sprites. But that isn't always going to be the case. It comes down to the image you want to repeat, it's height/width in relation to the sprite it exists on, the direction you want to repeat it, and the size of the container you want it to repeat in.
(source: sampsonresume.com)
This sprite could be repeated on the left 100px for use in a sidebar, while the other portions could serve as buttons and roll-over states in a navigation. with a small change, you could make the repeatable portion horizontal.
If you want a cross-browser solution, then currently you're out of luck, especially if you want a CSS-solution.
The only way to do it with JavaScript would be through the canvas element, but that's not supported by IE.
CSS cannot do this. You can however do it server-side or by using SVG graphics or Flash. Note that doing it with a plugin would not technically be a 'background-image", you'd need to position your content over the top of it.
