For the blockquote and the auther and date box add the below code at Appearance -> Customize -> Additional CSS
blockquote {
margin-top: 35px;
padding-left: 32px;
}
blockquote:before{
top: 2%;
font-family: Georgia, “Times New Roman”, serif;
color: #6394bf;
}
.metabox span {
font-family: var(–primary-font);
}
Try and let us know if it resolves the issues.
