Screen size and logo image adjustment is automatic based on responsive coding built into Joomlart templates and T4/T3 framework. I don't have to do anything and yes the Logo images shrink and enlarge all based on what's loading the pages. Tablets (widescreen) show Logo image Center and shrunk slightly from normal desktop browsing. Desktop also depends on screen size and I've set limits using JA-Resort default options so that both menu and logo images only view on large screen displays.
Looks like I'll have to pull out some docs for HTML 5 and Bootstrap 4 options to eliminate the Logo Image from adjusting in size and setting on one specific logo image size that will work on most or 80% of my viewers. Figured this was built-in to JA/T4 templates by default, but maybe my questions was simply too confusing to figure out the problems I'm having. Thanks anyways....
