Enfold Single Author Bloq Posts element remove image/meta on mobile

I have used both

.blog div.big-preview.single-big { display: none !important;}
and
.small-preview, .big-preview.single-big { display: none;}
to remove preview images and I’ve used

.post_author_timeline {display: none !important;}
and
.blog-tags, .blog-categories, .blog-author {display: none !important;}
to remove the timeline and the tag/categories/author meta

I want to streamline the Single Author Blog Posts element.

However, these CSS do not work in mobile. The images/tags/categories/author and timeline all show up on mobile devices for the Single Author Blog Posts elements.

What additional CSS do I need to enter to remove them from mobile.

Thanks, Chad
