I’m using css marker as follows ( the svg has an atribute of 32px width and height)
.texto-caracteristica-servicios li::marker {
content: url('../img/circlecheck.svg');
}
And this happens
SVG Code
<svg xmlns="http://www.w3.org/2000/svg" height='32' width='32' viewBox="0 0 20 20" fill="black">
<path fill-rule="evenodd" d="M10 18a8 8 0 100-16 8 8 0 000 16zm3.707-9.293a1 1 0 00-1.414-1.414L9 10.586 7.707 9.293a1 1 0 00-1.414 1.414l2 2a1 1 0 001.414 0l4-4z" clip-rule="evenodd" />
</svg>
