Thanks to @Lucas_Pires, I now have a much more reliable way to do my notifications tab. I guess I did not really need Cloudinary with the CSS magic here, and can let Glide handle the on/off status of the icon instead of creating 4 separate images.
<pre><span><style>
button[aria-label="Notifications"]::before {
content: "{N}";
position: absolute;
font-size: 9px;
font-weight: 800;
color: white;
padding: 1px;
top: 6px;
right: 25px;
z-index: 1;
height: 16px;
width: 16px;
background-color: red;
border-radius: 70%;
}
With {N} being the number of notifications to show. Thanks to @Robert_Petitto for the lead to use CSS for this as well!!!
