Gaussian Blur onHover Using jQuery

Question

I am wondering if there is some way to apply a gaussian blur onto a div using jQuery (or CSS that jQuery can modify). I have looked into blur(), but at least with Safari, i

Answer 1

It has not been mentioned here that we can create an excellent realistic blur effect for text using CSS3 text-shadow. And, (yep, of course!) we can blur solid backgrounds and borders using box-shadow (inset shadows and multiple shadows are allowed, you know).

So I hope in most cases you can achieve a realistic blur effect combining:

1) image blur using canvas

2) text blur using text-shadow

3) solid background and borders blur using box-shadow

4) have I forgotten anything else?....

PS: I believe it's not possible to write a magic class that blurs any html.

The restrictions that can't be overcome: blur the border of the image, blur embedded media

filter: blur(10px);
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);
filter: url(blur.svg#blur);
filter:progid:DXImageTransform.Microsoft.Blur(PixelRadius='10');

content of blur.svg

<svg version="1.1" xmlns="http://www.w3.org/2000/svg">
  <filter id="blur">
    <feGaussianBlur stdDeviation="10" />
  </filter>
</svg>

Answer 3

Be aware that Blur is when a DOM-element, such as textboxes (inputs etc.) loses focus, and should not be mixed with the kind of blur you are talking about (gaussian/motion blur).

There is no good cross-browser solution for this problem. You can, however, blur images by using a API such as the one Ben suggests. Or by using this one.

Maybe if you find out a way to draw your div contents to a HTML5 canvas you can then apply the Blur-filter by using Pixastic?

Check out the blur.js plugin for jQuery: http://blurjs.com, it uses my Stack Blur algorithm which I believe is currently the fastest JavaScript based way to blur canvas elements: http://www.quasimondo.com/StackBlurForCanvas/StackBlurDemo.html
