Accessing linked SVG element with CSS - html

I have this SVG included in my HTML
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 128.00456 127.33362" width="0" height="0" position="absolute">
<defs>
<pattern id="e" xlink:href="#b" patternTransform="matrix(1.006 0 0 1 288.184 313.89)"/>
<pattern id="b" xlink:href="#c" patternTransform="matrix(1.006 0 0 1 -.206 0)"/>
<pattern id="c" width="119.183" height="42.49" patternUnits="userSpaceOnUse" patternTransform="translate(288.338 309.89)">
<path fill="none" id="circle-top-fill" stroke="#000" stroke-width="3.971" stroke-miterlimit="1" d="M2.614 39.184A62.015 62.015 0 0 1 59.83 1.987a62.015 62.015 0 0 1 56.752 37.9" stroke-linecap="square" stroke-dasharray="0.99275, 0.99275"/>
</pattern>
<path fill="url(#e)" d="M288.39 313.89v40.173h119.693V313.89H288.39z" id="circle-top" transform="translate(-283.99 -313.89)" />
</defs>
</svg>
Then I use it in the page with
<svg class="circle">
<use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#circle-top"/>
</svg>
Now I need to add different colors to it (eg. add class .circle--blue to .circle).
When I use
.circle--blue use #circle-top-fill {
stroke: blue;
}
it doesn't work. Apparently fill="url(#foo)" doesn't create shadow DOM.
Is there any way to access #circle-top-fill when needed?
TL;DR: I have inline SVG definitions in my HTML. Then I want to use it on several places on the page with different colors.
Edit: jsfiddle example

Is it legal to put <svg> resources after </body>?

Can I put svg resources used in the website behind the end of body, in order to keep
them outside of what will be rendered?
In short: Is it legal to do the following?
<!DOCTYPE html>
<html>
<head>...</head>
<body>
<svg xmlns:xlink="http://www.w3.org/1999/xlink"

As mentioned before in the comments:
It's not valid and many browser won't display your elements.
So inserting your svg assets at the top or bottom of your <body> is the preferrable method.
Caution: Hiding your asset svg via display:none will break some referenced definitions like:
filters
gradients
masks and clip-paths
It works flawlessly for shape elements (like icons)
Example
function displayNone() {
document.querySelector('#svgAssets').style.display = 'none';
}
svg {
border: 1px dotted #ccc;
height: 10em;
display: inline-block;
}
<p><button onclick="displayNone()">Set display:none</button></p>

<symbol id="ellipse" viewBox="0 0 200 100">
<ellipse cx="100" cy="50" rx="100" ry="50" />
</symbol>
</svg>
In the above example I'm using <symbol> elements which could be used as an alternative to <defs>. They also support different viewBox properties for each icon.
If you just need to place icons via <use> you could also use external file references like so:
<svg viewBox="0 0 315.424 315.424">
<use href="svgIcons.svg#arrow" fill="red" />
</svg>
However, your svg files need to be same domain (or send with appropriate CORS headers)

If the purpose is not to have the original #arrow rendered in the document, you might include it inside the svg in the body, wrapped around defs.
Demo in the snipped below.
<svg xmlns:xlink="http://www.w3.org/1999/xlink"

How to display SVG with <use>

I am trying to use <use> tag to display an SVG. I am using Wordpress and have the file under the upload folder (as any other media). For some reason the <use> doesn't show, on the browser it show width and height as 0, even though I have inlined them in it.
My code:
<svg viewBox='0 0 153 91'>
<use href='https://example.com/wp-content/uploads/2021/04/arrow.svg' width='30' height='18'>
</svg>
In the Browser:
<svg viewBox="0 0 153 91">
<use href="https://example.com/wp-content/uploads/2021/04/arrow.svg" width="30" height="18">
</use>
</svg>
The svg file:
<svg fill="none" stroke="#fff" stroke-linecap="round" stroke-width="9.17" viewBox="0 0 153 91"><path d="m18.898 45.191h115.04"/><path d="m108.181 18.898 25.757 26.293-25.757 26.293"/></svg>
BONUS: Could the SVG be inlined somewhere in the <body> instead of the file uploaded?

This was missing on the SVG
xmlns="http://www.w3.org/2000/svg" xmlns:xlink= "http://www.w3.org/1999/xlink"
Final SVG should be:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink= "http://www.w3.org/1999/xlink"
>
<symbol id="arrow" viewBox="0 0 153 91" fill="none" stroke="#fff" stroke-linecap="round" stroke-width="9.17">
<path d="m18.898 45.191h115.04"/><path d="m108.181 18.898 25.757 26.293-25.757 26.293"/>
</symbol>
</svg>

Add border to an svg

I have an SVG used as a divider and I was wondering if on the curve of the svg, I can add a blue or black border that follows the path of the curve.
<svg width="100%" height="96px" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" preserveAspectRatio="none">
<path fill="#f4f6ff" d="M0,0 C40,33 66,52 75,52 C83,52 92,33 100,0 L100,100 L0,100 L0,0 Z"></path>
</svg>

Sure - just draw a path with a stroke on top of the shape.
<svg width="100%" height="96px" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" preserveAspectRatio="none">
<path fill="#f4f6ff" d="M0,0 C40,33 66,52 75,52 C83,52 92,33 100,0 L100,100 L0,100 L0,0 Z"></path>
<path fill="none" stroke="grey" stroke-width="1px" d="M0,0 C40,33 66,52 75,52 C83,52 92,33 100,0"></path>
</svg>
You can also stroke the original path and use a stroke-dasharray of the appropriate construction to make the dash cover just the top of the shape. Or you can use a svg filter to add a border to the top edge. Just drawing the border explicitly is the most straightforward.

You can use the CSS filter property if you can't directly edit the SVG to add the path (which might be a better way to go).
svg path {
filter: drop-shadow(0 -2px 0 blue);
}
<svg class="curve" width="100%" height="96px" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" preserveAspectRatio="none">
<path fill="#f4f6ff" d="M0,0 C40,33 66,52 75,52 C83,52 92,33 100,0 L100,100 L0,100 L0,0 Z"></path>
</svg>

How can I see the icons inside the SVG file?

I want to see all the icons inside the SVG file. I have tried to insert it into the HTML file with an img tag but I see a blank page.
<svg aria-hidden="true" style="position: absolute; width: 0; height: 0; overflow: hidden;" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

</symbol>
</defs>
</svg>

The code you provided contains only <symbols>. This is used to house SVG definitions that can be reused in different parts of the document. You would use them like this:
<svg>
<use xlink:href="#icon-triangle-left" />
</svg>

svg: change fill color using css

I have this svg file which I want to use with different colors
I have tried the following
<object type="image/svg+xml" width="100" height="100" data="todo.svg">
<span/>
</object>
(Not sure if OBJECT is the correct element for this)
Here is the content of todo.svg
<svg version="1.1" id="Layer_1" xmlns="..." x="0px" y="0px"
width="156px" height="141.6px" viewBox="0 0 156 141.6" enable-background="new 0 0 156 141.6" xml:space="preserve">
<g>
....
<g id="bar">
<path fill-rule="evenodd" clip-rule="evenodd" fill="#000" d="..."/>
</g>
</g>
....
So in the css I tried to style this as follows
#bar path { fill: #444; }
Doesn't work :( Any suggestions how I can change this svg property using css ?
