Dear Sir How to set a Full Width content area I need to show 5 items in one line > Delta Theme

@ABB URDU NEWS
Find line in style.css that starts with:
.products.grid .simple-prod, .white .simple-prod
change here this:
width: calc(25% - 16px);
into this:
width: calc(20% - 16px);
You may want to adjust also number of items per row on mobile, but I leave this on you.
Code for mobile devices is in responsive.css
