SVG Dark Mode

Vivek Gupta·December 3, 2023·0 comments

Recently I came across a challenge of a changing SVG icon colours on carkmode. The SVG was a logo exported from Adobe Illustrator. [Profile 1.1, Fonts converted to outlines, 5 decimal places, CSS properties in Style elements]. The SVG definition looked something like the following

<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 28.0.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<svg version="1.1"

     viewBox="0 0 930.41 965.292" 
     style="enable-background:new 0 0 930.41 965.292;" 
     xml:space="preserve">

The full SVG was AIIMS logo. I planned on using core-framework with it

Deleted the Image block

	<image style="display:none;overflow:visible;" width="1669" height="1651" xlink:href="C6C7760A975F4698.jpg"  transform="matrix(0.5971 0 0 0.5971 -49.6374 -14.7503)">

Edited the CSS Styles block

<style type="text/css">
  	svg {--logo_primary : #550b92;}
	@media (prefers-color-scheme: dark) {
            svg {--logo_primary : yellow;}
         }
	.darkmode, .dark, .cf-theme-dark, .theme-inverted {--logo_primary : yellow;}	
	
	.st0{fill:none;stroke:var(--logo_primary, black);stroke-width:18;stroke-miterlimit:10;}
	.st1{fill:none;stroke:var(--logo_primary, black);stroke-width:14;stroke-miterlimit:10;}
	.st2{fill:none;stroke:var(--logo_primary, black);stroke-width:8;stroke-miterlimit:10;}
	.st3{display:none;}
	.st4{display:inline;}
	.st5{enable-background:new    ;}
	.st6{fill:#000080;}
	.st7{display:inline;fill-rule:evenodd;clip-rule:evenodd;fill:#000080;}
	.st8{display:inline;fill:none;stroke:#000080;stroke-width:8.1;stroke-linecap:round;stroke-linejoin:round;stroke-miterlimit:1.0125;}

Use following JS to toggle darkmode

document.querySelector('svg').classList.toggle('darkmode');
document.querySelector('svg').classList.toggle('darkmode');

document.querySelector('svg').classList.toggle('dark');
document.querySelector('svg').classList.toggle('dark');

document.querySelector('svg').classList.toggle('cf-theme-dark');
document.querySelector('svg').classList.toggle('cf-theme-dark');Code language: JavaScript (javascript)

Corrected namespace for serif

Added the namespace for serif to avoid errors
