Prevent logo resizing

I am using a photo module in Themer for my logo.
I don’t want it to resize when the browser gets smaller. I want it to behave like the Beaver Builder logo here on the site. How do I do that?
Thank you

you can define the column with % for each responsive breakpoint e.g

so that it has always enough room!

Thank you for your answer.
I don’t want to prevent stacking, I want my logo to stay the same size.
Right now it resizes with the browser. I want to prevent auto-adjustment of height.
Just like the beaverbuilder logo on the Beaverbuilder site.
