Scaling Rshiny dashboard to fit different size screens

Need Shiny dashboard expert. It looks great on my 27-inch desktop monitor. However, the images don't fit on my 13-inch laptop. I suspect that the dashboard won't fit on many of the screens my clients will be using. I need a person to make the dashboard fit different size screens.

I believe there is a person that knows how to do this work immediately. Examples of shiny apps at different screen sizes are a big plus. PLEASE DO NOT CLAIM YOU CAN DO THE WORK JUST TO LEARN ON THE JOB. I DO NOT HAVE TIME. $200 US Fixes Price.
