Hi there,
If they’re not in columns, it would be this:
.wp-show-posts .wp-show-posts-entry-title {
font-size: 25px;
}If they’re in columns, try this:
.wp-show-posts-columns .wp-show-posts-entry-title {
font-size: 25px;
}As for the padding, you should be able to use the option in the “Columns” section.
