Hi,
Thank you for loving our theme.
1/ It's Masonry Layout - use without sidebar ( when you're using Sidebar, it will change to 2 columns )
2/ Please add more this code to Customize > Custom CSS to do that:
\
.penci-wrap-masonry{ margin-left: -10px; margin-right: -10px; }\
.penci-masonry .item-masonry{ padding: 0 10px; margin-bottom: 30px; }\
@media only screen and (min-width: 1170px){\
.penci-masonry .item-masonry{ width: 25%; }\
}3/ I'm not clearly about this question, but I think you can go to Customize > Featured Slider Options > on "Featured Slider Style" > pick one slider style you love for use.
Best Regards,
PenciDesign
