Is it possible to programatically control fill color of individual cells of svg pattern?

<svg viewBox="200 190 500 500" id="example">
<defs>
<pattern id="patt" x="0" y="0" width="20" height="20" patternUnits="userSpaceOnUse">
<g stroke="black" strokeWidth="0.5" >
<path id='a' fill='green' d="M0,0.054V20h21V0.054H0z M15.422,18.129l-5.264-2.768l-5.265,2.768l1.006-5.863L1.64,8.114l5.887-0.855 l2.632-5.334l2.633,5.334l5.885,0.855l-4.258,4.152L15.422,18.129z"/>
</g>
</pattern>
</defs>
<g fill="url(#patt)" stroke="orange" >
<circle cx="450" cy="300" r="100"/>
</g>
</svg>
Requirement is to create a pattern of svg in which fill color of each element in the pattern has to be manipulated.

Only when you create all colored shapes inside the <pattern> yourself:
<svg-pattern colors="green,red,blue,yellow"></svg-pattern>
<svg-pattern colors="purple,hotpink,hotpink,purple"></svg-pattern>
<script>
customElements.define("svg-pattern", class extends HTMLElement {
connectedCallback() {
let colors = this.getAttribute("colors").split(",");
let star = `v20h21v-20h-21zm15.4 18-5.3-2.8-5.3 2.8 1-5.9-4.3-4.2 5.9-.9 2.6-5.3 2.6 5.3 5.9.9-4.3 4.2 1 6z`;
let id = "unique" + Math.random();
this.innerHTML = `<svg width="180" height="180" style="display:inline-block" viewBox="0 0 200 200">
<defs>
<pattern id="${id}" x="0" y="0" width="40" height="40" patternUnits="userSpaceOnUse">
<g stroke="black" strokeWidth="0.5" >
<path fill='${colors[0]}' d="m0 0 ${star}"/>
<path fill='${colors[1]}' d="m20 0 ${star}"/>
<path fill='${colors[2]}' d="m0 20 ${star}"/>
<path fill='${colors[3]}' d="m20 20 ${star}"/>
</g>
</pattern>
</defs>
<g fill="url(#${id})">
<circle cx="100" cy="100" r="100"/>
</g>
</svg>`;
}
});
</script>

How can I make a toggle to toggle the visibility of an inline SVG?

I'm making a website where you can create your own character in order to learn more about SVGs. I want the user to be able to select different poses.
I was wondering how I could toggle the visibility of an SVG on the website to make one disappear and another appear.
Here is my SVG code:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 720 720" style="enable-background:new 0 0 720 720;" xml:space="preserve">

</g>
<g id="hair">
<path class = "hair" d="M107.4,276.86c-2.76-50.59,10.76-81.24,24.2-100.13C189.57,95.31,331.92,112,341.92,57.91

</svg>
The SVG is just a sample right now before I make the actual assets.

Variable text in SVG defined text tag

I would like to re-use def-ined shapes in SVG but with variable text.
Is the following somehow possibel ?
<svg width="1000pt" height="1000pt" viewBox="0.00 0.00 1000.00 1000.00" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
<g id="shape">
<rect x="10" y="0" rx="5" ry="5" width="80" height="40" style="fill:lightblue;stroke-width:0,opacity:0.5" />
<text text-anchor="middle" x="40" y="20" font-family="Helvetica,sans-Serif" font-size="8.00">variable_text</text>
</g>
</defs>
<g transform="translate(0 0)">
<use xlink:href="#shape" text="test" />
</g>
<g transform="translate(100 0)">
<use xlink:href="#shape" text="test2" />
</g>
</svg>
EDIT: since the solution would probably involve some javascript I have added the tag.

Clone the template and adjust as necessary.
let shape = document.getElementById("shape");
Array.from(document.getElementsByTagName("use")).forEach((use) => {
let text = use.getAttribute("text");
let clone = shape.cloneNode(true);
// might want to do something more robust here
clone.children[1].textContent = text;
use.parentNode.appendChild(clone);
use.parentNode.removeChild(use);
})
<svg width="1000pt" height="1000pt" viewBox="0.00 0.00 1000.00 1000.00" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

</g>
</defs>
<g transform="translate(0 0)">
<use xlink:href="#shape" text="test" />
</g>
<g transform="translate(100 0)">
<use xlink:href="#shape" text="test2" />

SVG Animation works in Chrome, but doesn't in Firefox and other browsers

Okay, so I have an SVG that is basically a clock animation. It works as intended in Chrome when I'm testing it, but loses form when I try it in Firefox or Safari.
This is the SVG in question:
<svg id="svg" width="100%" viewBox="-400 -150 800 300" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"

</g>
</mask>
</defs>
<g stroke-width="7" stroke-linecap="round" mask="url(#mask)">
<g stroke="hsla(0, 95%, 25%, 1)">
<use xlink:href="#sec" />
</g>
<g stroke="hsla(188, 15%, 35%, 1)">
<use xlink:href="#min" />
</g>
<g stroke="hsla(218, 5%, 15%, 1)">
<use xlink:href="#hr" />
</g>
</g>
</svg>
<script>
window.onload = function () {
var now = new Date();
var h = now.getHours(), m = now.getMinutes(), s = now.getSeconds();
var curr = h * 60 * 60 + m * 60 + s;
svg.setCurrentTime(curr);
};
</script>
The second hand moves to the next position all the way from the top instead of animating from the previous place. You can test this yourself. This is the link to the code hosted on codepen.
