Change logo height

Hi @brunoslaw123
you may do all the changes using child theme (basic CSS knowledge required): https://developer.www.ads-software.com/themes/advanced-topics/child-themes/
Here you may download prepared by us child theme (links are in top section): https://blogonyourown.com/themes/boyo/
Just install and… modify.
And please read the comments in files ??

The other way to have smaller image is to upload image in smaller size or edit/crop in wp-admin area.

I hope it helps you a bit.

Best,
Patryk
