CSS Blur in IE 11 - css

I have been trying to get A css blur effect in IE 11 for hours and did not make any progress. I tried to use the following simple html:
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
.blur{
-ms-filter:progid:DXImageTransform.Microsoft.Blur(PixelRadius='50');
}
</style>
</head>
<body>
<img src='http://img3.wikia.nocookie.net/__cb20120627075127/kirby/en/images/0/01/KDCol_Kirby_K64.png' class="blur" />
</body>
</html>
I also tried just using the filter without the ms prefix. I saw that filter code on http://jsbin.com/ulufot/31/edit and even consulted the microsoft example http://samples.msdn.microsoft.com/workshop/samples/author/filter/blur.htm which does not work in my IE 11 on Win7. Do you have any ideas, what I could be doint wrong?
probably interesting if you are struggling too: http://ie.microsoft.com/testdrive/Graphics/hands-on-css3/hands-on_svg-filter-effects.htm


According to this blog (http://demosthenes.info/blog/534/Cross-browser-Image-Blur-with-CSS) the blur filter was dropped after IE9:
filter:progid:DXImageTransform.Microsoft.Blur(PixelRadius='3');
They did give a solution called StackBlur (using JavaScript and Canvases):
http://quasimondo.com/StackBlurForCanvas/StackBlurDemo.html
It is in the form of a javascript add-on downloadable from that site.


Here's a solution that works in IE10+ by using SVG:
https://jsfiddle.net/joegeringer/g97e26pa/8/
<svg width="230" height="120" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" class="svgBlur">
<filter id="svgBlurFilter">
<feGaussianBlur in="SourceGraphic" stdDeviation="5" />
</filter>
<image xlink:href="http://lorempixel.com/400/200" x="0" y="0" height="200" width="400" class="nonblurred" />
<image xlink:href="http://lorempixel.com/400/200" x="0" y="0" height="200" width="400" class="blurred" filter="url(#svgBlurFilter)" />
</svg>

SVG animated background stops about half way scrolled down

test.html:
<body style="background-image:url(test.svg);background-size:cover">
<div style="height:2000px"> Hello! </div>
</body>
test.svg (taken from https://developer.mozilla.org/en-US/docs/Web/SVG/Element/animate):
<?xml version="1.0"?>
<svg width="120" height="120" viewBox="0 0 120 120" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<rect x="10" y="10" width="100" height="100">
<animate attributeType="XML" attributeName="x" from="-100" to="120"
dur="10s" repeatCount="indefinite"/>
</rect>
</svg>
When I scroll about half way down the page, the animation pauses (actually, stops refreshing). Not sure why. Can't find anything on it in SVG specification, or google chrome documents...
My browser version Chromium 73.0.3683.86 Built on Ubuntu, running on LinuxMint 18.

it's a chromium thing i think, the browser thinks that the svg is outside ur screen so it pauses it to save resources, u can put a div inside the one with the background and give the second div a height: 100vh; and overflow: auto;

SVG artwork clipped on right edge

I am fairly new to SVG, and the part that always confuses me is the size of the SVG and the clipping at the edges. I have an SVG square in the below checkbox art I was trying to add a dropshadow to:
Turned out the code to do this is simple; but the right edge is clipped off. I tried various combinations of widths and such, no luck. What am I missing?

you need to set width on the filter:
<filter id="blurFilter" y="-5" height="40" width="40">
fiddle
for an explanation you can look into filter feOffset definition;
shortly the reason is this filter primitive offsets the input image relative to its current position in the image space by the specified vector.

Can't control SVG icon fill color with CSS styles

I have read all post in here about styling my svg fill color with CSS but without luck.
What I want is to able to make an icon with a link. My external svg file is grey, but I would like to make it red with css and change color to yellow when hovering.
I think I am targeting the SVG wrong. Please help. My test is here:
testpage
<%#LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<style type="text/css">

</style>
<body>
<table width="100%" border="0" class="tabelform">

Answer a little overdue, but worth having for reference for others.
Basically, the only type of SVG usage which can be used in conjunction with CSS is the inline usage.
This means you would literally put your SVG markup directly into the HTML source as follows:
<div class="my-svg">
<svg xmlns="http://www.w3.org/2000/svg" id="SVG-dropdown-icon" viewBox="0 0 15 11">
<title>
Expand
</title>
<path d="M1.758 1L7.5 6.582 13.242 1 15 2.709 7.5 10 0 2.709z"/>
</svg>
</div>
NOTE: This SVG has been optimised using SVGO and then manually edited to include and ID
You can now control the SVG using CSS like so:
.my-svg {
fill: pink;
}
.my-svg:hover {
fill: red;
}
currentColor
You can also use the currentColor keyword in the SVG to apply a colour to certain elements of it, for example:
<div class="my-svg">
<svg id="SVG-active-icon" viewBox="0 0 25 25" xmlns="http://www.w3.org/2000/svg">
<title>
Current Event
</title>
<g fill="none" fill-rule="evenodd">
<circle class="activeEventPulse" stroke="currentColor" fill="#EBEBED" cx="12.5" cy="12.5" r="11.5"/>
<ellipse fill="currentColor" cx="12.5" cy="12.5" rx="4.5" ry="4.5"/>
</g>
</svg>
</div>
.my-svg {
color: red;
}
JS Fiddle
This can be handy if you need to use the same SVG across different websites / themes, such as dark and light, for easily switching SVG colours with CSS.
Caching / performance consideration: SVG cloning
You should also keep in mind, it's not a good idea to use inline SVG for repetitive images, such as icons, because they can not be cached (the SVG code will be repeated throughout your HTML, increasing the ultimate file size).
Instead, one approach I like to use is to create an SVG index at the top of my page, which contains all the SVGs I want to use on the page, for example:
<svg xmlns="http://www.w3.org/2000/svg" class="svg-index">
<svg xmlns="http://www.w3.org/2000/svg" id="SVG-dropdown-icon" viewBox="0 0 15 11">
<title>
Expand
</title>
<path d="M1.758 1L7.5 6.582 13.242 1 15 2.709 7.5 10 0 2.709z"/>
</svg>
<svg id="SVG-active-icon" viewBox="0 0 25 25" xmlns="http://www.w3.org/2000/svg">
<title>
Current Event
</title>
<g fill="none" fill-rule="evenodd">
<circle class="activeEventPulse" stroke="currentColor" fill="#EBEBED" cx="12.5" cy="12.5" r="11.5"/>
<ellipse fill="currentColor" cx="12.5" cy="12.5" rx="4.5" ry="4.5"/>
</g>
</svg>
</svg>
Make sure you set the SVG index to display: none so it doesn't show up on the page.
You can now reuse these SVGs repetitively throughout the page using the xlink:href attribute as follows:
<svg class="dropDown">
<use xlink:href="#SVG-dropdown-icon" />
</svg>
<svg class="active">
<use xlink:href="#SVG-active-icon" />
</svg>
<svg class="active">
<use xlink:href="#SVG-active-icon" />
</svg>
<svg class="dropDown">
<use xlink:href="#SVG-dropdown-icon" />
</svg>
JS Fiddle
This is called cloning, and allows you to take advantage of cacheable SVGs which can be controlled with CSS!
Hope this helps!

try to use inline svg instead of external svg source then you can control

is there any way to use an svg (img) to crop an image?

As far as I understand (by reading previously posted questions on stackoverflow) that cropping an image using svg coorindates is possible, but it is possible to crop an image by using an svg link? for example: <img src="http://imgh.us/face01.svg">
EDIT: This is what I meant:
Thanks!

Yes. You can do it using the mask-image property. This is supported on all browsers except IE.
.masked {
-webkit-mask-image: url(http://imgh.us/face01.svg);
mask-image: url(http://imgh.us/face01.svg);
}
<img src="http://lorempixel.com/400/400" width="400" height="400" class="masked">
Unfortunately you will still need to make other arrangements for IE.

You can do it all inside SVG using the image element combined with a SVG mask or a SVG filter and have it work on IE10+ (and all other browsers). Here is the filter example:
<svg width="400px" height="400px">
<defs>
<filter id="crop-me" x="0%" y="0%">
<feImage xlink:href="http://imgh.us/face01.svg" result="area"/>
<feComposite operator="in" in="SourceGraphic" in2="area"/>
</filter>
</defs>
<image filter="url(#crop-me)" xlink:href="http://lorempixel.com/400/400" x="0" y="0" width="200" height="300"/>
</svg>

Apply a responsive SVG image mask to a HTML5 video

I have already did a one-day search before posting but with no luck
My problem:
I have a HTML5 video in a wrapper with a solid colour (e.g. blue) background (fig.1).
I want to apply a 2-colour .png 1440x900 image mask (fig. 2) over the video so to obtain, as a final result, a video with some transparent parts, corresponding to the black squares of the image mask (and the mask should scale proportionally with video, so as to be somehow responsive)
What actually happens
With the attempted solution (see below) I can see nothing (latest Chrome and Firefox): the page is completely blue coloured and the video starts
What I tried
I tried some demos found here and here but in both the examples the mask applied is not made with an image. Here's the basic code I'm trying.
<!DOCTYPE html>
<head>
<!--[if IE]><script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]-->
<style>
body {
background: #5a91b4;
}
div {
width: 1440px;
}
video {
width: 100%;
mask:url('#imask');
-webkit-mask:url('mask.svg');
}
</style>
</head>
<body>
<div>
<video autoplay controls>
<source src="http://www.html5multimedia.com/code/media/parrots-small.mp4" type="video/mp4">
<source src="http://www.html5multimedia.com/code/media/parrots-small.webm" type="video/webm">
</video>
</div>
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 1440 900">
<defs>
<mask id="imask" >
<image width="1440" height="900" xlink:href="http://copy.com/TCImDzmSoq8CrU8W/mask.png"></image>
</mask>
</defs>
</svg>
</body>
</html>
The mask.svg file:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" id="vmask" preserveAspectRatio="xMinYMin"
viewBox="0 0 1440 900"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
<mask>
<image width="1440" height="900" xlink:href="http://copy.com/TCImDzmSoq8CrU8W/mask.png"></image>
</mask>
</defs>
</svg>
I'm also open to evaluate a different approach to obtain the same effect.
Thank you in advance guys

If you convert your mask in pure SVG, it will work line in this demo http://jsbin.com/xejiko/1/edit

And in the css you call it
-webkit-mask-box-image: url(urlto/mask.svg)

Not sure about SVG but in CANVAS this would be easy. All you need to do is do is copy the video to the canvas and do the source-atop http://codepo8.github.io/canvas-masking/
Of course you'll run into the issue that you can not access the video that is not on the same domain :/
