Blur effect on a div element

问题

Is it possible to add a gaussian blur on div element? If yes, how I can do this?

回答1:

I think this is what you are looking for? If you are looking to add a blur effect to a div element, you can do this directly through CSS Filters-- See fiddle: http://jsfiddle.net/ayhj9vb0/

 div {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  width: 100px;
  height: 100px;
  background-color: #ccc;

}

I got blur working with SVG blur filter:

CSS

-webkit-filter: url(#svg-blur);
        filter: url(#svg-blur);

SVG

<svg id="svg-filter">
    <filter id="svg-blur">
        <feGaussianBlur in="SourceGraphic" stdDeviation="4"></feGaussianBlur>
    </filter>
</svg>

Working example:

Please note - this will not work in IE versions
