Svg inside another svg can't change height with css - css

Example
In this example I've posted, I have two svg elements, each with a nested element with its own viewbox.
svg {
background-color: orange;
}
#inline {
background-color: yellow;
}
#in-css {
width: 50px;
}
<svg viewbox="0 0 300 300" width=100 height=100>
<rect x=50 y=30 width=100 height=100></rect>
<svg id="inline" width="50px" viewbox="50 50 100 100">
<rect width=50 height=50 x=80 y=80></rect>
</svg>
</svg>
<svg viewbox="0 0 300 300" width=100 height=100>
<rect x=50 y=30 width=100 height=100></rect>
<svg id="in-css" viewbox="50 50 100 100">
<rect width=50 height=50 x=80 y=80></rect>
</svg>
</svg>
Problem
Setting the width or height attribute of the inner svg works if I do it inline, but I can't set it if I try targeting that element with css. Does anybody know why? I'm using chrome for reference if that helps :)

Why isn't the style tag in this SVG affecting elements?

I have a simple SVG with a single element, that has a fill of red:
<svg width="100" height="60" viewBox="0 0 100 60" fill="none" xmlns="http://www.w3.org/2000/svg">
<path fill="red" d="M4.93141 44.3745H2.8013V59.6912H4.93141V44.3745Z"/>
</svg>
I have added a stylesheet, and made the element use the class, but the element is not green per the code below:
<svg width="100" height="60" viewBox="0 0 100 60" fill="none" xmlns="http://www.w3.org/2000/svg">
<style type="text/css" >
.foreground {
fill: "green";
}
</style>
<path class="foreground" d="M4.93141 44.3745H2.8013V59.6912H4.93141V44.3745Z"/>
</svg>
Why is the inline style not affecting the element with the class?
I have tried various combinations of CDATA, <defs> etc (per various examples) and haven't found a solution so far.

Because there is no need for the double quote around green.
<svg width="100" height="60" viewBox="0 0 100 60" fill="none" xmlns="http://www.w3.org/2000/svg">
<style type="text/css" >
.foreground {
fill: green;
}
</style>
<path class="foreground" d="M4.93141 44.3745H2.8013V59.6912H4.93141V44.3745Z"/>
</svg>

How to use SVG clipPath with Pattern via CSS clip-path property?

The initial SVG figure with pattern:
<svg width="200" height="200" viewBox="0 0 100 100">
<defs>
<pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%">
<circle cx="2" cy="2" fill="white" r="0.8"></circle>
</pattern>
<mask id="img-dotted-mask">
<rect width="100" height="100" fill="url(#img-dotted-dots)"></rect>
</mask>
</defs>
<path d="M0 0 H 100 V 100 H 0 Z" mask="url(#img-dotted-mask)" fill="#1063B1"></path>
</svg>
Need to achieve:
One instance of the SVG figure with pattern for refferencing with CSS as clip-path.
I have tried to create SVG clipPath element and bind to CSS clip-path by this way
.figure {
width: 300px;
height: 300px;
clip-path: url(#img-dotted-clip-path);
background-color: #1063B1;
}
<div class="figure"></div>
<svg width="0" height="0" viewBox="0 0 100 100">
<defs>
<clipPath
clipPathUnits="objectBoundingBox"
id="img-dotted-clip-path">
<pattern
patternUnits="objectBoundingBox"
patternContentUnits="objectBoundingBox"
x="0" y="0" height="0.1" width="0.1">
<circle cx="0" cy="0" fill="white" r="0.5"></circle>
</pattern>
</clipPath>
</defs>
</svg>
Nothing happens.
Expected result - the same as the previous snippet.
For comparing:
If I use SVG rect - CSS clip-path works.
If pattern - doesn't
.figure {
width: 300px;
height: 300px;
clip-path: url(#img-dotted-clip-path);
background-color: #1063B1;
}
<div class="figure"></div>
<svg width="0" height="0" viewBox="0 0 100 100">
<defs>
<clipPath
clipPathUnits="objectBoundingBox"
id="img-dotted-clip-path">
<rect width="1" height="1"></rect>
</clipPath>
</defs>
</svg>

The only things that are valid inside a clip path are:
Shape elements (‘circle’, ‘ellipse’, ‘line’, ‘path’, ‘polygon’, ‘polyline’, ‘rect’)
‘text’
‘use’
Plus you can use animation elements etc to animate the clip path. However, only the shapes of those elements are used. Effects such as patterns, filters, etc are ignored.
The only way you could get the effect you want to work as a clipping path would be to add numerous <circle> elements to your <clipPath>.
<clipPath>
<circle>
<circle>
<circle>
<circle>
... etc ...
</clipPath>
But you could use a mask instead. Masks allow patterns.
.figure {
width: 300px;
height: 300px;
-webkit-mask: url(#img-dotted-mask);
mask: url(#img-dotted-mask);
background-color: #1063B1;
}
<p>This only works in Firefox</p>
<div class="figure"></div>
<svg width="0" height="0">
<defs>
<pattern id="img-dotted-pattern"
viewBox="0 0 1 1"
patternUnits="userSpaceOnUse" x="0" y="0" width="20" height="20">
<rect width="1" height="1" fill="black"/>
<circle cx="0.5" cy="0.5" fill="white" r="0.15"></circle>
</pattern>
<mask id="img-dotted-mask">
<rect width="2000" height="2000" fill="url(#img-dotted-pattern)"/>
</mask>
</defs>
</svg>
However inline SVG masks applied to HTML elements, like my example above, only work in Firefox. To get an SVG mask to work in Chrome, you would need to use mask or mask-image with an external or Data URL (as Temani has done in their answer).

You can recreate the same thing using mask combined with radial-gradient
.figure {
width: 300px;
height: 300px;
background:linear-gradient(to right,red,#1063B1);
/*radius here size here*/
-webkit-mask:radial-gradient(3px, #fff 97%,transparent 100%) 0 0/20px 20px;
mask:radial-gradient(3px, #fff 97%,transparent 100%) 0 0/20px 20px;
}
body {
background:#f2f2f2;
}
<div class="figure"></div>
Or consider the SVG inside the mask property. Make sure to escape the # and correctly set the viewbox and width/height to have a perfect repeat
.figure {
width: 300px;
height: 300px;
background:linear-gradient(to right,red,#1063B1);
-webkit-mask:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="200" height="192" viewBox="0 0 100 90"><defs><pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%"><circle cx="2" cy="2" fill="white" r="0.8"></circle></pattern><mask id="img-dotted-mask"><rect width="100" height="100" fill="url(%23img-dotted-dots)"></rect></mask></defs><path d="M0 0 H 100 V 100 H 0 Z" mask="url(%23img-dotted-mask)" fill="%231063B1"></path></svg>');
mask:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="200" height="192" viewBox="0 0 100 90"><defs><pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%"><circle cx="2" cy="2" fill="white" r="0.8"></circle></pattern><mask id="img-dotted-mask"><rect width="100" height="100" fill="url(%23img-dotted-dots)"></rect></mask></defs><path d="M0 0 H 100 V 100 H 0 Z" mask="url(%23img-dotted-mask)" fill="%231063B1"></path></svg>');
}
body {
background:#f2f2f2;
}
<div class="figure"></div>

Fill Colour on <use> Element For a <symbol> Isn't Changing Colour

I'm trying to change the fill colour on an SVG symbol when it is inside a <use> element. Because there are going to be multiple instances of the symbol on the page, I can't do this is the <symbol> element, because the different instances of <use> will be different colours.
I've can't seem to get it work though. In the example below I would like to the bottom instance to be a blue twitter icon.
In the CSS I've done #bottom-twitter svg path {fill:blue;} which doesn't work. And I can't seem to get anything to work.
Any help would be amazing.
#box1 {
height: 5rem;
width: 5rem;
}
/* NOT WORKING */
#bottom-twitter svg path {
fill:blue;
}
<svg id="twitter" style="display: none;">
<defs>
<symbol id="twitter-symbol" viewBox="0 0 19.19 15.95">
<path id="twitter-path" d="M19.19,1.92a8.76,8.76,0,0,1-2.28.64A3.9,3.9,0,0,0,18.63.32a6.87,6.87,0,0,1-2.52,1A3.87,3.87,0,0,0,13.23,0,4,4,0,0,0,9.32,4,3.41,3.41,0,0,0,9.44,5,11,11,0,0,1,1.32.72a4.29,4.29,0,0,0-.52,2A4,4,0,0,0,2.56,6.12,3.61,3.61,0,0,1,.76,5.6v0a4,4,0,0,0,3.16,4,4.35,4.35,0,0,1-1,.16,4.9,4.9,0,0,1-.76-.08,4,4,0,0,0,3.68,2.8A7.79,7.79,0,0,1,.92,14.19a6.78,6.78,0,0,1-.92,0A10.83,10.83,0,0,0,6,16c7.24,0,11.19-6.16,11.19-11.47V4a6.83,6.83,0,0,0,2-2">

</svg>
<svg id="bottom-twitter" viewBox="0 0 19.19 15.95">

The problem is the fill="#000" in the svg path. Remove that or just change it to be the color you want.
#box1 {
height: 5rem;
width: 5rem;
}
/* NOT WORKING */
#bottom-twitter {

Responsive clip-path with inline SVG

On an element with a background (image or solid color don't really matter):
<header id="block-header"></header>
I am trying to apply a clip-path using SVG. To achieve this, I am putting SVG inline into the same element like this:
<header id="block-header">
…
<svg width="100%" height="100%" viewBox="0 0 4000 1696" preserveAspectRatio="none">
<defs>
<clipPath id="myClip">
<path d="M0 1568.18V0h4000v1568.18S3206.25 1696 2000 1696C984.37 1696 0 1568.18 0 1568.18z"/>
</clipPath>
</defs>
</svg>
…
</header>
You can run the code snippet below or check the JSFiddle. You can see original SVG image (in black) put inline, having curviness along the bottom and being responsive. In contrast, the red rectangle shows the same image applied (or, rather, not applied) as a clip-path.
I guess I misunderstand either viewBox or preserveAspectRatio attributes though can not find what is exactly wrong here. Any help would be appreciated.
#block-header {
background: Red;
min-height: 100px;
-webkit-clip-path: url(#myClip);
clip-path: url(#myClip);
}
<h1>SVG image</h1>
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100" viewBox="0 0 4000 1696" preserveAspectRatio="none"><path d="M0 1568.18V0h4000v1568.18S3206.25 1696 2000 1696C984.37 1696 0 1568.18 0 1568.18z"/></svg>
<h1><code>clip-path</code> using the same SVG</h1>
<header id="block-header">
<svg width="100%" height="100" viewBox="0 0 4000 1696" preserveAspectRatio="none">
<defs>
<clipPath id="myClip">
<path d="M0 1568.18V0h4000v1568.18S3206.25 1696 2000 1696C984.37 1696 0 1568.18 0 1568.18z"/>
</clipPath>
</defs>
</svg>
</header>

References to SVG clip paths are to the clip path definitions themselves and the dimensions or other attributes of the <svg> are meaningless in this context.
What is happening in your example is that you are applying a 4000 px wide clip path to your header. Which is probably only of the order of 900 px wide. So the curvature isn't visible.
If you want a responsive clip path, you should define it using clipPathUnits="objectBoundingBox".
#block-header {
background: Red;
min-height: 100px;
-webkit-clip-path: url(#myClip);
clip-path: url(#myClip);
}
<h1>SVG image</h1>
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100" viewBox="0 0 1 1" preserveAspectRatio="none"><path d="M0,0 1,0 1,0.9 C 1,0.9, 0.77,1, 0.5,1 0.23,1, 0,0.9,0,0.9z"/></svg>
<h1><code>clip-path</code> using the same SVG</h1>
<header id="block-header">
<svg width="0" height="0">
<defs>
<clipPath id="myClip" clipPathUnits="objectBoundingBox">
<path d="M0,0 1,0 1,0.9 C 1,0.9, 0.77,1, 0.5,1 0.23,1, 0,0.9,0,0.9z"/>
</clipPath>
</defs>
</svg>
</header>

Using CSS approach how to set an image to fill a path in SVG?

I want to create a CSS class to fill a path with image that can be applied on any SVG path and fill that path with image. The image must be stretch to fit that path.
To achieve this; I create a pattern with image tag and set the width and height as 100%. but the image takes 100% of the whole screen instead of objectBoundingBox of the container (in this case svg tag).
Below is the sample code:
.myClass {
fill: url(#image);
stroke: red;
stroke-width: 5;
}
<svg id='pattern' xmlns="http://www.w3.org/2000/svg" version="1.1">
<defs>
<pattern id='image' x=0 y=0 width="100%" height="100%" patternUnits='objectBoundingBox'>
<image xlink:href='myImage.png' x=0 y=0 width="100%" height="100%" preserveAspectRatio="none"></image>
</pattern>
</defs>
</svg>
<svg id='triangle' xmlns="http://www.w3.org/2000/svg" version="1.1" width='300px' height='300px'>
<path d='M0 0 L300 0 L300 300 Z' class='myClass'></path>
</svg>
May be I am doing something wrong.
Please suggest any solution for this problem.

Here's your thing working - http://jsfiddle.net/eAfTc/
.myClass {
fill: url(#image);
stroke: red;
stroke-width: 5;
}
<svg id='pattern' xmlns="http://www.w3.org/2000/svg" version="1.1">
<defs>
<pattern id='image' width="1" height="1" viewBox="0 0 100 100" preserveAspectRatio="none">
<image xlink:href='http://dummyimage.com/600x400/abc/333' width="100" height="100" preserveAspectRatio="none"></image>
</pattern>
</defs>
</svg>
<svg id='triangle' xmlns="http://www.w3.org/2000/svg" version="1.1" width='300px' height='300px'>
<path d='M0 0 L300 0 L300 300 Z' class='myClass'></path>
</svg>
Note that there's a patternContentUnits and a patternUnits, they do different things. Personally I prefer to use a viewBox for defining the coordinate system.
Here's a new example showing the pattern applied to various elements of different sizes and aspect ratios, it also gets rid of the first svg fragment.
Update: I added 'preserveAspectRatio' to the <pattern> element, and a new example showing the stretching and scaling.
