After a lot of trial and error, I added these lines to the bottom of
core_blockstatus.less
in my child theme.
CSS:
.message-cell .messageNotice
{
text-align: center;
font-size: 18px;
color: #101854 !important;
background-color: #affbf9 !important;
}
I had to use
!important
to make it work. Is that okay, or is there a better way to make the changes?
