After coming across an inspiring HTML newsletter, I was motivated to add some keyframes animations to a MailChimp template. To my disappointment, the animation works perfectly on local setup, but once uploaded to MailChimp, the @keyframe
rules along with the %
get stripped out, transforming it from...
@keyframes fadein {
0% { opacity:0 }
100% { opacity:1 }
}
...to this...
0 { opacity: 0 }
100 { opacity:1 }
It appears that MailChimp is not properly interpreting and removing these elements. Despite searching for solutions in MailChimp support, I haven't found anything useful. Has anyone come up with a clever workaround for this issue?
