Hi,

How do I reduce the line height in the heading & make the meta text "Read more" smaller?

passcode: trythis

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
/* line height */
.view-list .blog-title {
    line-height: 15px;
}
/* read more */
a.blog-more-link {
    font-size: 30px !important;
}
}

Thanks!!!!!
