I have a similar issue with the effects of one code displaying only when I go to Design --> Custom CC. It has to do with this code specifically, which creates a translucent-white background for text in a specified block:
#block-848b3e4b0bc6ae27ccc5 { <---- my block ID
background-color: #f0f0f088;
padding: 1px;
text-align: center;
}
Any ideas what went wrong?
