I'm using TailwindCSS and want to change the color of an svg. Without Tailwind this question has been asked before here, for 2020 this should be a good answer but Tailwind does not support those filters. There is a guide in the docs on how to work with svg icons but this tutorial works without files, just the plain text paths.
I downloaded the svg files and assign the path to the svg to the image's src tag. The following example shows my problem, I want the icon's background to be red and the icon's color to be blue. Unfortunately it's not possible for me to change the icon color.

What is the correct workflow when downloading svg icons and use them directly by linking the assets path? All I want to achieve is something like this
<a href="https://twitter.com" target="_blank">
<img src="pathToSvgInAssetsFolder" />
</a>
and set the icon color to a custom Tailwind color e.g. red-500. So whenever I want to change the icon color I can simply modify the color class.
Does someone know how to do it?
The workflow for adding SVG to your Tailwind project should be done using inline SVG.
Adam Watham the creator of Tailwind CSS made a video about working with inline SVG in Tailwind. In the video he shows a workflow you would use to prep an unoptimized SVG for a Tailwind project. Here's the steps with one extra step he didn't mention:
Drop the SVG file or paste the SVG markup into the optimizer at SVGOMG.
Copy the markup provided by SVGOMG and paste into your project.
Remove any fill or stroke attributes so Tailwind can modify those with classes (not shown in the video).
Remove any XMLNS attributes or XML tags, these are not needed for inline SVG.
Add Tailwind classes.
If you're using a component based framework it's recommended that you also extract the icons into components that can be reused throughout your application.
The benefits of this approach:
Full control over the size and color of your SVG icons
Faster load speed since the icons are part of the HTML
Here's an example based on the Fiddle you shared in the comments. I ran the SVGs through SVGOMG and removed the fill attributes so Tailwind can control that.

I often scan through the elements in websites and keep seeing things like:

<use x="0" y="0" width="13" height="13" xlink:href="/images/icons/icon_definitions.svg#heart"></use></svg>
How can I use the icons like that on my website? I tried going to W3.org to find out how but it is not very clear how to do it, if at all I can. Anyone care to explain?
You will see similiar code if you open any .svg file in some text editor. It's just two-dimensional vector described in XML language which can be directly used in HTML.
SVG is a language based on XML for describing two-dimensional vector and mixed vector/raster graphics.
source: w3.org/TR/SVG2/
As an example you can check iconsvg.xyz. Each of these icons are downloadable as .svg but you can see their code right above the download button.
I don't know much about SVG icons but I've used some in my project. The format is as shown below in the snippet I created. There is a website I use with free icons but they are not as much. The website is https://iconsvg.xyz/. It gives you the full code of the icon you will choose where you just paste it into your HTML file.

To display content in the Angular 7 components, we are using JSON. I have come to an issue with using the SVG icons from our UX team when serving them to the component via JSON. I know that using the img tag it will not allow me to use a CSS class to change the icons color and will require multiples of the same icon and is not ideal for this project. I have tried multiple ways to get this to work. I have tried embedding the svg string via
"icon": "data:image/svg+xml;charset=utf-8,<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path fill="none" d="M0 0h24v24H0z"/><path d="M9 16.2L4.8 12l-1.4 1.4L9 19 21 7l-1.4-1.4L9 16.2z"/></svg>",
<embed [src]="items.icon">
but I get the error "Unexpected token h in JSON at position 64"
I also tried using interpolation within the SVG tag, but I get a similar error as above.
I have also tried interpolation within a div tag, but I get the path instead of an icon.
What I need to be able to do-
1. Place SVGs in JSON and serve it to the component via interpolation.
2. Change the class on the SVG to change colors and opacity
Is there any documentation for using SVGs in Angular 7 components via interpolation from JSON?
For the data you have you should use src on a img tag.
<img [src]="item.icon">
It is even better if you could use it as HTML tag.
"icon": "<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path fill="none" d="M0 0h24v24H0z"/><path d="M9 16.2L4.8 12l-1.4 1.4L9 19 21 7l-1.4-1.4L9 16.2z"/></svg>",
<div [innerHTML]="items.icon"></div>
I'm looking for an advice about work with SVG images, respectively icons.
What I've tried
If I'm using PNG icons, the CSS is like:
elem:after {background: url('icon.png'); ...}
I've tried the same way
elem:after {background: url('icon.svg'); ...}
but it isn't what I'm looking for. This solution lose advantages of SVG icons (they're small and blured, fuzzy).
What I have
I've generated this code online using Icomoon app.
<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">
<defs>
<symbol id="icon-love" viewBox="0 0 33 32">
<title>love</title>
<path d="M32.916 15.597c0.604-0.66 ..."></path>
</symbol>
<symbol id="icon-shop" viewBox="0 0 34 32">
<title>shop</title>
<path d="M17.148 27.977c-..."></path>
</symbol>
</defs>
</svg>
<svg class="icon icon-shop">
<use xlink:href="#icon-shop"></use>
</svg>
My question
Is it semantically correct to put icons into HTML markup, instead of putting them into CSS?
Across whole website there is about 60 icons, any unique, any are repeated more times. Generated markup above has about 50kB.
Can I put all icons into general layout template and load them all in whole website, or include just icons I use in the page?
Here I've found How to change color of SVG image using CSS (jQuery SVG image replacement)? (3 years ago), but don't know if it's the right way.
How to cache SVG properly? Is it posible when I use it like I'm writing above?
I read many articles, but not definitely sure how to do that best way.
Thanks for advice.
So I'm building a website and I can't get the svg icon to show up correctly on my MacBook's Touch Bar when I add the site to my favourites list.
The webpage in question can be found here: http://japesfawcett.com
I have an SVG file that is a black thunderbolt on a white background, and I am using the following code for the Touch Bar icon:
<link rel="mask-icon" href="img/favicon.svg" color="#000000">
The code of the SVG is as follows:

For some reason the Touch Bar icon for the site is appearing all white with no image visible in it. I can't get the SVG to be visible at all!
If anyone has any insights as to how to fix this it'd be greatly appreciated, it's been driving me mad!
It seems like that the problem lies in your SVG, which is incorrectly cropped (it's outside the 16x16 pixel bounds defined by the viewBox). Replace the path in it with the following:

Also, the icon should be completely black, so you should change the fill property of the st0 class:
.st0{fill:#000;}
