I’m seeing this issue as well whereby a tag class is causing my logo to change size depending on which single page template I’m using.
At left is a page using a single page template that also has a hero section applied via condition (terms, happy files folder taxonomy).
At right is the home page which is only bricks and does not have the same hero section applied.
Why would the styles for the logo in the header load differently if they are not part of the single page template?
