Internet Explorer 9-11 does not fill g element with color (highcharts) - css

Using, highcharts I'm trying to get the fill color to work properly on IE. In the picture below, you'll see the background is transparent (no color at all). I need it to be black with an opacity of 0.8.
Changing the fill css property in Firefox/Chrome will change the color.
What do I need to do to get the fill property to show up?
Example Markup:
<g class="highcharts-tooltip" zIndex="8" style="cursor:default;padding:0;white-space:nowrap;" visibility="hidden" opacity="0" transform="translate(295,43)">
<rect rx="3" ry="3" fill="none" x="0.5" y="0.5" width="92" height="46.046875" isShadow="true" stroke="black" stroke-opacity="0.049999999999999996" stroke-width="5" transform="translate(1, 1)"></rect>
<rect rx="3" ry="3" fill="none" x="0.5" y="0.5" width="92" height="46.046875" isShadow="true" stroke="black" stroke-opacity="0.09999999999999999" stroke-width="3" transform="translate(1, 1)"></rect>
<rect rx="3" ry="3" fill="none" x="0.5" y="0.5" width="92" height="46.046875" isShadow="true" stroke="black" stroke-opacity="0.15" stroke-width="1" transform="translate(1, 1)"></rect>
<rect rx="3" ry="3" fill="0.5" x="0.5" y="0.5" width="92" height="46.046875" stroke="#e87c05" stroke-width="1" anchorX="104.5" anchorY="31"></rect>
<text x="8" y="21" style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:12px;color:#ffffff;fill:#ffffff;" zIndex="1">
<tspan style="fill:#acacac" x="8">Excellent</tspan>
<tspan style="font-weight:bold" x="8" dy="16">91</tspan>
<tspan dx="0"> Responses</tspan>
</text>
</g>

It was staring me right in the face. The <rect> elements have a fill of none. Change those, and it works as expected.

background color not appying on Text tag inside svg [duplicate]

I want to color the background of svg text similar to background-color in css
I was only able to find documentation on fill, which colors the text itself
Is it even possible?
You could use a filter to generate the background.
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" result="bg" />
<feMerge>
<feMergeNode in="bg"/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">solid background</text>
</svg>
No this is not possible, SVG elements do not have background-... presentation attributes.
To simulate this effect you could draw a rectangle behind the text attribute with fill="green" or something similar (filters). Using JavaScript you could do the following:
var ctx = document.getElementById("the-svg"),
textElm = ctx.getElementById("the-text"),
SVGRect = textElm.getBBox();
var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect");
rect.setAttribute("x", SVGRect.x);
rect.setAttribute("y", SVGRect.y);
rect.setAttribute("width", SVGRect.width);
rect.setAttribute("height", SVGRect.height);
rect.setAttribute("fill", "yellow");
ctx.insertBefore(rect, textElm);
The solution I have used is:
<svg>
<line x1="100" y1="100" x2="500" y2="100" style="stroke:black; stroke-width: 2"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.6em">Hello World!</text>
<text x="150" y="105" style="fill:black">Hello World!</text>
</svg>
A duplicate text item is being placed, with stroke and stroke-width attributes. The stroke should match the background colour, and the stroke-width should be just big enough to create a "splodge" on which to write the actual text.
A bit of a hack and there are potential issues, but works for me!
Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.
No, you can not add background color to SVG elements. You can do it programmatically with d3.
var text = d3.select("text");
var bbox = text.node().getBBox();
var padding = 2;
var rect = self.svg.insert("rect", "text")
.attr("x", bbox.x - padding)
.attr("y", bbox.y - padding)
.attr("width", bbox.width + (padding*2))
.attr("height", bbox.height + (padding*2))
.style("fill", "red");
Answer by Robert Longson (#RobertLongson) with modifications:
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow"/>
<feComposite in="SourceGraphic" operator="xor"/>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50"> solid background </text>
<text x="20" y="50" font-size="50">solid background</text>
</svg>
and we have no bluring and no heavy "getBBox" :)
Padding is provided by white spaces in text-element with filter.
It's worked for me
Going further with #dbarton_uk answer, to avoid duplicating text you can use paint-order=stroke style:
<svg>
<line x1="100" y1="100" x2="350" y2="100" style="stroke:grey; stroke-width: 100"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.5em; fill:black; paint-order:stroke; stroke-linejoin:round">Hello World!</text>
</svg>
Note the stroke-linejoin:round which is needed to avoid seeing spikes for the W sharp angle.
You can combine filter with the text.

<text fill="black" x="20" y="50" font-size="30">text with color</text>
</svg>
</body>
</html>
this is my favorite hack (not sure it should work). It refer an element that is not yet displayed, and it works pretty well
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 620 40" preserveAspectRatio="xMidYMid meet">
<defs>
<filter x="-0.02" y="0" width="1.04" height="1.1" id="removebackground">
<feFlood flood-color="#00ffff"/>
</filter>
</defs>
<!--Draw the text-->
<use xlink:href="#mygroup" filter="url(#removebackground)" />
<g id="mygroup">
<text id="text1" x="9" y="20" style="text-anchor:start;font-size:14px;">custom text with background</text>
<line x1="200" y1="18" x2="200" y2="36" stroke="#000" stroke-width="5"/>
<line x1="120" y1="27" x2="203" y2="27" stroke="#000" stroke-width="5"/>
</g>
</svg>
For those wondering how to apply padding to a text element when it has a background like in the Robert's answer, do the following:
<svg>
<defs>
<filter x="-0.1" y="-0.1" width="1.2" height="1.2" id="solid">
<feFlood flood-color="#171717"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">Hello</text>
</svg>
In the example above, filter's x and y positions can be used as transform: translate(-10%, -10%) would, and width and height values can be read as 120% and 120%. So we made background 20% bigger, and offsetted it -10%, so background is now 10% bigger on each side of the text.
The previous answers relied on doubling up text and lacked sufficient whitespace.
By using atop and I was able to get the results I wanted.
This example also includes arrows, a common use case for SVG text labels:
<svg viewBox="-105 -40 210 234">
<title>Size Guide</title>
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">

An obvious workaround to the problem of the blur produced by the filter effect is to render the <text> two times: once for the background (with transparent characters) and once for the characters (without a background filter).
For me, this was the only way to make the text readable in Safari.
<svg width="100%" height="100%">
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" />
</filter>
<g transform="translate(20, 50)" font-size="50">
<text aria-hidden="true" fill="none" filter="url(#solid)">solid background</text>
<text fill="blue">solid background</text>
</g>
</svg>
The aria-hidden="true" attribute is there to prevent screen readers from speaking the text twice, if the user uses a screen reader.
You can add style to your text:
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px,
rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"
White, in this example.
Does not work in IE :)

I want it like my screenshot http://take.ms/ViaOB is it possible?
In your pattern tag, replace patternUnits="userSpaceOnUse" with patternContentUnits="objectBoundingBox". Then add height="1" width="1" preserveAspectRatio="none" to the image tag inside your pattern tag. Like this:
<pattern id="img1" id="pattern1" patternContentUnits="objectBoundingBox" width="100%" height="100%" >
<image height="1" width="1" preserveAspectRatio="none" xlink:href="https://images.unsplash.com/photo-1534002778889-3f1b078de59b?ixlib=rb-0.3.5&ixid=eyJhcHBfaWQiOjEyMDd9&s=a2e808d0d3560da6d4845fe7e7bfc19d&auto=format&fit=crop&w=750&q=80" x="0" y="0" />

unwanted horizontal line from svg mask

I'm rendering a line using an SVG mask and gradient, similar to how Github renders sparklines for their "year of activity" charts that are displayed when viewing and organization's list of repositories.
For some reason when the width of the SVG is a certain value, a horizontal line appears at the top of the lines:
The line appears to correspond to the SVG group element that houses a rectangle which is applied a mask and a gradient fill:
However, resizing the SVG to a different width results in the line not displaying:
Here is the markup for an example SVG:
body {
background: #000;
}
<svg width="281" height="50">
<defs>
<linearGradient id="gradient-36" x1="0" y1="0" x2="0" y2="1">
<stop offset="0%" stop-color="#f03b20"></stop>
<stop offset="50%" stop-color="#feb24c"></stop>
<stop offset="100%" stop-color="#ffeda0"></stop>

And here is a link to live code showing the bug:
https://bl.ocks.org/clhenrick/ed231b1ba92c87f82529c153e7c77a4e/4954afeeccc9b2d61547e08bb901a8ae23c32c83
Here is a link to an example using the same technique with no bug, just a different size width for the SVG, mask, rect and different sized path:
https://bl.ocks.org/clhenrick/e0b06bbb361780f818993e956dccc5d8/d1fcd24b4df5571ed7069f4a45ed9932a48d74c2
Furthermore, with the buggy example when I move the path element out of the mask and into the group element, the path looks correct:
https://bl.ocks.org/clhenrick/b1ac9490a5708afbcb3ef7f93bb45b3a/5df5bd70333da98d866e7f59e3dd74060ff87474
I'm not sure why this happens at certain SVG widths or SVG path sizes and not at others.
It's not clear to me why github do their sparklines graphs using that complicated arrangement of rects, masks, and transforms. It appears it may be triggering a bug in Chrome.
Have you considered just simplifying the graph? Just use the sparkline path on its own, and apply the gradient directly to it?

Am not sure what is causing the issue but here is a work around to avoid it. The idea is to hide this line by changing the position of the rect (its y value).
So here is the buggy SVG :

This will of course affect the fill you are applying as it's a linear background. So you may change it to adjust the color as you need.
I made more tests trying to point out what can be the cause of the issue. I tried to eliminate some part of the SVG (like the linear-gradien) and to change some values and here is what i got :
body {
background: black;
}
svg {
display: block;

The first one is the buggy and when i tried to add the path directly into the SVG it works fine (the second one). In the third one i changed the value of stroke in the path to make it 3 and the line disappeared.
I can conclude that it's because you are using the path as a mask. It can be a bug related to some browser and not a bug with your code. In this case you can simply consider using the path directly as an element (and you have a lot of possiblities to color it using gradient) or use my trick in order to hide the bug.

SVG <animate> offset from 0 not working

The purpose of the animation is that fill background colour as loading battery. The solution seems to me apple gradient animation which shows as loading. But in the current SVG linearGradient animate not working when attribute offset="0%"

Chaning the code to this

<animate attributeName="x1" dur="5s" from="-100%" to="100%" repeatCount="indefinite" />
</linearGradient>
Makes the gradient split the background-color in the two colors, and moves it from -100% to 100%, making it possible to go from 0% to 100%, while giving it the exact same effect.
I've now also added the animation you wanted. It is being triggered by clicking on the svg element.
Here's a Fiddle of the result
Hope this helps

Background color of text in SVG

I want to color the background of svg text similar to background-color in css
I was only able to find documentation on fill, which colors the text itself
Is it even possible?
You could use a filter to generate the background.
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" result="bg" />
<feMerge>
<feMergeNode in="bg"/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">solid background</text>
</svg>
No this is not possible, SVG elements do not have background-... presentation attributes.
To simulate this effect you could draw a rectangle behind the text attribute with fill="green" or something similar (filters). Using JavaScript you could do the following:
var ctx = document.getElementById("the-svg"),
textElm = ctx.getElementById("the-text"),
SVGRect = textElm.getBBox();
var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect");
rect.setAttribute("x", SVGRect.x);
rect.setAttribute("y", SVGRect.y);
rect.setAttribute("width", SVGRect.width);
rect.setAttribute("height", SVGRect.height);
rect.setAttribute("fill", "yellow");
ctx.insertBefore(rect, textElm);
The solution I have used is:
<svg>
<line x1="100" y1="100" x2="500" y2="100" style="stroke:black; stroke-width: 2"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.6em">Hello World!</text>
<text x="150" y="105" style="fill:black">Hello World!</text>
</svg>
A duplicate text item is being placed, with stroke and stroke-width attributes. The stroke should match the background colour, and the stroke-width should be just big enough to create a "splodge" on which to write the actual text.
A bit of a hack and there are potential issues, but works for me!
Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.
No, you can not add background color to SVG elements. You can do it programmatically with d3.
var text = d3.select("text");
var bbox = text.node().getBBox();
var padding = 2;
var rect = self.svg.insert("rect", "text")
.attr("x", bbox.x - padding)
.attr("y", bbox.y - padding)
.attr("width", bbox.width + (padding*2))
.attr("height", bbox.height + (padding*2))
.style("fill", "red");
Answer by Robert Longson (#RobertLongson) with modifications:
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow"/>
<feComposite in="SourceGraphic" operator="xor"/>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50"> solid background </text>
<text x="20" y="50" font-size="50">solid background</text>
</svg>
and we have no bluring and no heavy "getBBox" :)
Padding is provided by white spaces in text-element with filter.
It's worked for me
Going further with #dbarton_uk answer, to avoid duplicating text you can use paint-order=stroke style:
<svg>
<line x1="100" y1="100" x2="350" y2="100" style="stroke:grey; stroke-width: 100"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.5em; fill:black; paint-order:stroke; stroke-linejoin:round">Hello World!</text>
</svg>
Note the stroke-linejoin:round which is needed to avoid seeing spikes for the W sharp angle.
You can combine filter with the text.

</svg>
</body>
</html>
this is my favorite hack (not sure it should work). It refer an element that is not yet displayed, and it works pretty well
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 620 40" preserveAspectRatio="xMidYMid meet">
<defs>
<filter x="-0.02" y="0" width="1.04" height="1.1" id="removebackground">
<feFlood flood-color="#00ffff"/>
</filter>
</defs>
<!--Draw the text-->
<use xlink:href="#mygroup" filter="url(#removebackground)" />
<g id="mygroup">
<text id="text1" x="9" y="20" style="text-anchor:start;font-size:14px;">custom text with background</text>
<line x1="200" y1="18" x2="200" y2="36" stroke="#000" stroke-width="5"/>
<line x1="120" y1="27" x2="203" y2="27" stroke="#000" stroke-width="5"/>
</g>
</svg>
For those wondering how to apply padding to a text element when it has a background like in the Robert's answer, do the following:
<svg>
<defs>
<filter x="-0.1" y="-0.1" width="1.2" height="1.2" id="solid">
<feFlood flood-color="#171717"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">Hello</text>
</svg>
In the example above, filter's x and y positions can be used as transform: translate(-10%, -10%) would, and width and height values can be read as 120% and 120%. So we made background 20% bigger, and offsetted it -10%, so background is now 10% bigger on each side of the text.
The previous answers relied on doubling up text and lacked sufficient whitespace.
By using atop and I was able to get the results I wanted.
This example also includes arrows, a common use case for SVG text labels:

An obvious workaround to the problem of the blur produced by the filter effect is to render the <text> two times: once for the background (with transparent characters) and once for the characters (without a background filter).
For me, this was the only way to make the text readable in Safari.
<svg width="100%" height="100%">
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" />
</filter>
<g transform="translate(20, 50)" font-size="50">
<text aria-hidden="true" fill="none" filter="url(#solid)">solid background</text>
<text fill="blue">solid background</text>
</g>
</svg>
The aria-hidden="true" attribute is there to prevent screen readers from speaking the text twice, if the user uses a screen reader.
You can add style to your text:
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px,
rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"
White, in this example.
Does not work in IE :)
