Second one seems to be working with
.wrapper .wrapper_inner .content .content_inner .full_width .full_width_inner .wpsp-card .hentry .wp-show-posts-inner .wpsp-content-wrap .wp-show-posts-entry-header h2{
line-height:80% !important;
}
And first one with:
.wrapper .wpsp-card article{
margin-bottom:15px !important;
}
