Is there a css-only way to do background blur in IE11? RRS feed

  • Question

  • I want to make the background visible but blurred when a popup is opened. I am not asking about image blur, I am asking about adding blur to the page, and I want to know if there is currently any css-only solution?

    The non-css solutions I am aware of are:

    1. The solution which uses javascript uses libraries like
    2. To create an image of the background using libraries like html2canvas: and then insert the image inside an inline svg and apply svg filter blur to it.

    I have checked and verified that none of the following works in IE11:

    filter: blur(7px);
    -webkit-filter: blur(7px);
    filter: url(/images/blur.svg#blur);
    filter: url("data:image/svg+xml;utf9,<svg%20version='1.1'%20xmlns=''><filter%20id='blur'><feGaussianBlur%20stdDeviation='7'%20/></filter></svg>#blur");
    -moz-filter: blur(7px);
    -o-filter: blur(7px);
    -ms-filter: blur(7px);
    /* This only works for older IE. For newer IE using javascript is suggested here: */

    It will be very nice to get an official answer from someone from microsoft that this is not possible if that's the case.

    I also asked this on stackoverflow and did not get an answer:

  • Hi,

    If possible include with your questions a link to your website, or a jsfiddle mashup that shows the issue.

    f12>DOM Explorer tab, select the element your interested in.... on the rhs you will see the style rules and how they are applied to an element..... style rules cascade so you have to place back-compatible legacy style rules at the top of the rule.

    eg. filter should appear at the bottom of the rule block.
