Hello, I have made some customizations to the Quark theme. One in particular to include a border and left margin on the main content container, however, in doing this it has effected the responsiveness when viewed on a mobile device. How do I change the margin back to zero on mobile devices only?
I would appreciate any other advice on responsiveness after viewing the site as well. Thank you for your support and this great theme!
