Coveo Atomic Search Interface Styling - Atomic-Icon - Shadow Dom - html

I am trying to style Coveo's new Atomic React Wrapper using Shadow Dom. It doesn't appear they exposed the atomic-icon's svg elements as a part for both submit-button and clear-button. I was able to modify their colors by changing some of the variables.
atomic-search-box::part(clear-button){ width: 50px; height: 50px; }
This will affect the background of the svg but not the icon itself. Here is the rendered html of clear-button.
<button class="btn-text-transparent w-8 h-8 mr-1.5 text-neutral-dark ripple-parent ripple-relative" part="clear-button" aria-label="Clear"><atomic-icon class="w-3 h-3 hydrated ripple-relative" innerhtml="<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 18 18"><path d="m18 2-1.8-2-7.1 7.1-7.1-7.1-2 2 7.1 7.1-7.1 7.1 2 1.8 7.1-6.9 7.1 6.9 1.8-1.8-6.9-7.1z"></path></svg>"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 18 18"><path d="m18 2-1.8-2-7.1 7.1-7.1-7.1-2 2 7.1 7.1-7.1 7.1 2 1.8 7.1-6.9 7.1 6.9 1.8-1.8-6.9-7.1z"></path></svg></atomic-icon></button>
it looks like height and width are pulled from .w-3 .h-3 classes on the atomic-icon.
.h-3 {
height: 0.75rem;
}
Can I override those classes somehow or how would you increase the size of these elements?

At the time when you asked your question, there was indeed no easy way to edit those components.
However, within the last weeks, the clear-icon and submit-icon shadow parts have been released: https://docs.coveo.com/en/atomic/latest/reference/components/atomic-search-box/
I hope this helps!

Is there any way to import an SVG and then modify it?

Here is an endpoint for a logo that I will use in the example: https://rdanhgsjebvnzzvsohyx.supabase.co/storage/v1/object/public/assets/logos/logoaidvisor-purple.svg
So importing and rendering the SVG as an image and styling it using Tailwind CSS works perfectly fine:
<img src="https://rdanhgsjebvnzzvsohyx.supabase.co/storage/v1/object/public/assets/logos/logoaidvisor-purple.svg" alt="logo" class="w-28 sm:w-48 md:w-60" />
However, I can't find a way to modify the SVG as I would be able to do with "normal" SVGs.
note: I am working in a svelte project but I wish to find a universal solution that works no matter the framework, etc.
I tried giving the image attributes that id usually would give to SVGs such as fill:
<img src="https://rdanhgsjebvnzzvsohyx.supabase.co/storage/v1/object/public/assets/logos/logoaidvisor-purple.svg" alt="logo" class="w-28 sm:w-48 md:w-60" fill="#222" />
I assumed that would do the trick but it did not. after plenty of research, I still can't find a solution.
You simply cannot use img if you want to affect the SVG. Inline the SVG directly, that way styles can apply, as it generates the necessary elements that are targeted by the styles.
How exactly you would do this depends on your build system; many have ways of importing files as just their string contents, so you could e.g. use that in conjunction with {#html ...}. If the SVG comes from a DB you can create an API and fetch the contents from there.
(Note that SVGs can potentially execute scripts, so as with anything else, only use #html with secure/sanitized content.)
You can also use an external <use> element – similar in convenience to an <img> element.
Wrap your logo in a <symbol> element and apply an ID.
Remove fill attributes from the logo's <path> elements and add them to the <use> element
Copy the original viewBox attribute to your parent svg

Limitations: strict CORS policy
External <use> references must be hosted on same domain – otherwise browsers will block them due to cross origin security settings.
Other features like gradients, masks, clip-paths etc. might also not work.
For simple use cases like logos or icons it's still a suitable alternative to <img>.
However you might use an injecting/inlining script like svgxuse

How to modify svg icon colors with Tailwind

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.
<link href="https://unpkg.com/tailwindcss#1.8.10/dist/tailwind.min.css" rel="stylesheet" />

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.

How to use SVG for icons properly / best practices

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.

How to insert an SVG into a button?

I am new to HTML and stuff and I would like to insert a SVG into a button. I tried using <object> but the SVG is invisible. Any suggestions what I could do to make it visible and fit inside the box?
There are a few different approaches. Possibly the easiest way to include an SVG is using an <img> tag, like you would for any other image type:
<button>
<img src="https://api.iconify.design/ic-baseline-face.svg?height=24" aria-hidden="true">
Smile
</button>
In this case, the size of the SVG we're importing is about right, but if it wasn't it might be more difficult to size it how you like, because you have two elements rather than one to think about. In that case, a good alternative is to set it as a background in CSS instead:
.my-button {
width: 3em;
height: 3em;
background: url("https://api.iconify.design/ic-baseline-face.svg?height=24") center no-repeat;
}
<button class="my-button" aria-label="Smile"></button>
This approach is often used for icons, but note that in this method we have to specify a size (in this case using width and height in the CSS).
As a third option, you can include SVG source directly in HTML instead, which allows you to style it with CSS and manipulate it with JavaScript, but that's generally not very useful for button icons. For completeness, though you'd do it like this:
<button>
<!-- From https://material.io/tools/icons/?style=baseline -->

<path fill="none" d="M0 0h24v24H0z"/>
</svg>

css/svg create larger background image

I am trying to replace an existing libraries background image with a slightly larger version. For reference, it is just a little drag handle in the corner of a "draggable" item. Upon inspection, I see the original dev is just setting a little background-image like so:
position: absolute;
background: url(data:image/svg+xml;base64,PD94bWwgdmVyc2lvbj0iMS4wIiBzdGFuZGFsb25lPSJubyI/P…4yIDAgTCA2IDAgTCA2IDYgTCA2IDYgWiIgZmlsbD0iIzAwMDAwMCIvPg0JPC9nPg08L3N2Zz4=) bottom right no-repeat;
background-origin: content-box;
I am wondering how the data:image/svg+xml;base64,PD94bWwgdmVyc2lvbj0iMS4wIiBzdGFuZGFsb25lPSJubyI/P…4yIDAgTCA2IDAgTCA2IDYgTCA2IDYgWiIgZmlsbD0iIzAwMDAwMCIvPg0JPC9nPg08L3N2Zz4= was generated and if it is possible to make my own with just a slightly larger handle. I have access to tools like photoshop/illustrator but I am thinking maybe that is overkill. I want to make the little grey handle maybe 5px larger in each direction. Unsure where to start with this, any advice is welcome. Thanks!

The original developer used a clever technique called data URI to avoid an unnecessary request for an image resource*. This is done by using the syntax: data(mime-type;base64,base64-string).
Open a developer tools' console in your browser and run the following code (the base64 string is from your example):
atob('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')
The result is how the browser sees this image:
<?xml version="1.0" standalone="no"?>
<!-- Generator: Adobe Fireworks CS6, Export SVG Extension by Aaron Beall (http://fireworks.abeall.com) . Version: 0.6.1 -->
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg id="Untitled-Page%201" viewBox="0 0 6 6" style="background-color:#ffffff00" version="1.1"
xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xml:space="preserve"
x="0px" y="0px" width="6px" height="6px"
>
<g opacity="0.302">
<path d="M 6 6 L 0 6 L 0 4.2 L 4 4.2 L 4.2 4.2 L 4.2 0 L 6 0 L 6 6 L 6 6 Z" fill="#000000"/>
</g>
</svg>
You can edit the SVG code as you wish in any visual editor or just textually and then run in the browser's console btoa('updated-svg-code') on it. Wrap the resulting string with data:image/svg+xml;base64,%UPDATED% and use it as a background image.
For more information about atob and btoa JavaScript functions for base64-manipulation, see an article at MDN.
* - note that the price for avoiding an extra request is an increase by 33% of the CSS file size. This is usually mitigated by the usage of GZIP compression, though.
