Browser replacing part of a CSS class name with $merge.url
Has anyone seen this before?
Email looks great in clients. But on Mac only, clicking to view online (from web app or Mac Outlook app), the browser (Chrome, Firefox, Safari) displays partially-replaced CSS class names in the custom stylesheet, which I see in inspector:
Instead of:
.cta-text-for-regular-btn p { color: #FFFFFF; }
Browser displays:
$merge.url
-text-for-regular-btn p { color: #FFFFFF; }
The browser can't read that line of code, so the color reverts to its default.
What is $merge.url, and where might this be stemming from? I'm looking to be pushed in the right direction so I can focus on solutions. Thank you!
