Hi Shannon,
Thanks for writing in! You can add this under Custom > CSS in the Customizer.
/* Increase the font size of meta info */
.p-meta > span {
font-size: 13px;
}
/* hide author */
.p-meta > span:first-child {
font-size: 0;
}
.p-meta > span:first-child a {
font-size: 13px;
}
/* hide date */
.p-meta .entry-date {
display: none;
}
Hope this helps.
Cheers!
