Spinner
Firstly, grab an image, maybe from font awesome (Font awesome v5). Make sure you get the SVG image and put it into the HTML or add the SVG into the CSS. This was it's not treated as a character. Also, add the class of spinner to it so that we can style it.
<svg
aria-hidden="true"
focusable="false"
data-prefix="fas"
data-icon="circle-notch"
class="spinner svg-inline--fa fa-circle-notch fa-w-16"
role="img"
xmlns="http://www.w3.org/2000/svg"
viewBox="0 0 512 512">
<path
fill="currentColor"

</svg>
Next set up the CSS for the spinner
.spinner {
height: 30px;
width: 30px;
animation: spinner 0.7s linear infinite;
}
@keyframes spinner {
to {
transform: rotate(360deg);
}
}
